Zero Legion

"You wear the symbol of our chapter, the armor of the Astartes, knowing that you are no longer who you once were. Your being - body, mind and soul, are now committed to upholding the sworn oath we Space Marines took to the Emperor of Mankind. From hence forth you are the shield and sword of man. We now walk towards the future, while holding the history of mankind on our shoulders."

- Speech to all newly inducted Initiates of the Zero Legion.

The Zero Legion is a mysterious Space Marine Chapter of the 3rd Founding and uncertain lineage. There is very little information on them, and what little exists, is sealed away in the deepest vaults by the Inquisition. This unusual chapter has shown to possess numerous technologies and weaponry of the early days of the Imperium, thought loss during the Horus Heresy, as well as relic archaeotech from the Dark Age of Technology including incredible Warp Technology too. How they came to obtain such powerful and forbidden technology is unknown. These Astartes have shown to possess high resistance to the warp, as well as strong regenerative healing factors, able to reattach severed limbs. They have also shown a deep grudge against not just the Chaos Space Marines of the Traitor Legion, but also the Ecclesiarchy, viewing the former as a threat to mankind, and the latter as a disease. Despite that, they appear to have a good relationship with the Adeptus Mechanicus, for their sharing of their technology with the Tech-Priest of Mars, and several Adeptus Astartes Chapters, as well as strong resolve of the defense of humanity.

Chapter History
The Zero Legion is clouded in mystery in relation of their origins, as with most things about the Chapter. The earliest recorded sighting of this mysterious chapter was during when Abaddon the Despoiler launched his second Black Crusade. They aided Imperial forces, but they had remained silent and not communicative with other Imperial forces, only for strategic situations and speaking through their helmet vox-casters. They were reported to wield weapons thought lost during the Horus Heresy and not seen since the Dark Age of Technology, earning the attention of the Adeptus Mechanicus. Some knowledge of their past was that the majority of the chapter consisted of descendants the Auretian Technocracy, survivors saved by Xander Jarak, the sole living member of the Brotherhood. The survivors fled aboard warp faring vessels powered by Warp Gates before re-colonizing other worlds. A decade later the Great Scouring began and the ancestors joined the Imperium, though still retained the knowledge of their fallen civilization. Said history and lore of technology was passed onto their descendants who would be inducted into the Zero Legion.

The Nullifiers on Omega II
The first sighting of the Zero Legion appeared on the Hive World Omega II in 123.M32. The planet was currently under sieged by an Ork WAAAAGH! The Planetary Defense Force and Imperial Guard were doing their best to hold the greenskin tide back, but the Orks' relentlessness and numbers were slowly overwhelming them. The Planetary Governor had sent requests for aid, but there had been no response so far. It would seem that the world would be overrun soon.

Then, during the second month of fighting, reinforcements came. Thunderhawk Gunships struck Ork lines before they could reach the capital of Omega II. The greenskins were decimated by the sudden aerial strike, allowing drop pods to land unopposed. Marching out were silver and blue armored Adeptus Astartes, wielding weapons not seen since the Horus Heresy and even dating back to the Dark Age of Technology. The Space Marines gunned down the Orks before being reinforced by armour thought lost from the Horus Heresy. Once that was done, the leader of these Space Marines arrived and without a word, took command of the defenders and reorganized them to protect the free cities while his forces freed the rest of the planet. It only took two weeks, but the Space Marines eventually eliminated the Orks and took the Warlord's head. When Imperial Forces arrived, the Space Marines had already left. Questioned, the Governor said that the Chapter gave themselves no name.

Meeting on Minerva XI
Fascinated that a chapter held such ancient technology, the Fabricator General of Mars deeply wanted to meet this mysterious chapter. Accompanied by a Skitarii contingency along with Inquisitors, the investigation fleet searched the Omega System, as well as the neighboring ones and nearby sub-sectors. Their search finally bared fruit a year later, when another force of these mysterious Space Marines were spotted on the Civilised World of Minvera XI, just finished exterminating a Dark Eldar Kabal. Immediately, a group of Inquisitors and the Fabricator General arrived too meet the one who led these Space Marines.

Introducing himself as Commander Kred Domerus of the 5th Division, Kred revealed that they were a part of the Zero Legion Chapter. A month later, a fleet belonging to the Zero Legion arrived, with them was Rahdik Zoron, the Supreme Imperator of the Zero Legion, who met with the representatives. What happened or said during said meeting is unknown, but the eventually the Zero Legion was recognized as an official Adeptus Astartes Chapter of the Imperium of Mankind.

True Origins
Many who have come into contact with the Zero Legion have questioned their origins. While none doubt the chapter's loyalty to the Imperium, some have wondered where they come from. The chapter has also been under the investigation of many Inquisitors, particularly the Ordo Hereticus, who have noted the Zero Legion's dislike of the Eccleisarchy. So far there have been several theories:

Salamanders
The most popular theory. Given the Zero Legion's favour of technology, advanced weaponry and craftsmanship is similar to that of the Salamanders. Furthermore, the chapter's belief of self-reliance and independence is much like the Salamander's Promethean Cult, along with their dedication to protecting the citizens of the Imperium. During the Third War of Armageddon, Commander Elzart and Salamander Chapter Master, Tu'Shan, fought alongside one another protecting a mass of refugees from Ork bikers.

Iron Hands
The second theory of the Zero Legion's origins. Like the Salamanders, and given their high affinity with technology, as well as many of their advancements, it would make sense if the chapter was descended from the sons of Ferrus Manus, the Iron Hands, whom are well known for their use of bionics. However, they lack the harden and merciless traits of the sons of Medusa, making this theory difficult to back up.

Ultramarines
The Zero Legion are known to possess a large number of Astartes, a highly-stable gene-seed and great tactical skills. It would make sense if they were successors of the Ultramarines Chapter. However, Roboute Guilliman, the Ultramarines Primarch and Lord Commander of the Imperium, has not said anything about the chapter's origins and hasn't openly declared if the Zero Legion are his gene-sons, leaving this topic up to debate.

Grey Knights
With their strong resistance to the Warp, there have been theories if the Zero Legion are a successor chapter of the secretive Grey Knights, like the Exorcists. However, no records of the Grey Knights having another descendant chapter exist, or have been deeply hidden under orders of the Inquisition, and the Grey Knights have given no confirmation whether or not this true. Thus, the theory has been put on hold but still remains.

Alpha Legion
From the deepest corners of the Imperium, whispered quietly among the Inquisition, rumors that the Zero Legion might be a successor chapter of the Alpha Legion have begun to arise. Their ability to remain organized while spread out across the galaxy has been noted to be strong trait of the XXth Legion. Some of the more zealous Inquisitors would say that this would explain their rejection of the Imperial Creed. However, given the size of the Chapter, their achievements, as well as those who support them (i.e. the Adeptus Mechanicus, other Astarte Chapters and Radical Inquisitors) have kept them from launching a full investigation.

The Lost Legions
Another rumor of the chapter's possible origins insist that they may not come from the known loyalist Legions, but instead from the two Lost Legions, whose names and Primarchs were struck clean from all Imperial records. Many stated that this would explain the Zero Legion's large size and arsenal. Thus some Inquisitors and higher ranked Imperial officials believe that they could possibly be a successor chapter of either the II or XI Legions, or perhaps one of said Legions, or both of them combined. However, given the chapter's own secrecy towards their origins, and lack of information of the mentioned Legions, this theory remains in question.

Notable Campaigns

 * 2nd Black Crusade (597.M32): The Zero Legion sends 3 Divisions to fend off Abaddon's forces.


 * Defence of Gemstone-IV (668.M32-669.M32): The Zero Legion chapter's 6th and 19th Divisions appear to aid the besieged Hive World, Gemstone-IV from a massive Ork WAAAGH! The 7-week campaign is the first time the Zero Legion works alongside Imperial forces. The 19th Division assists in reorganizing the Planetary Defense Forces, while the 6th Division attacks the Orks' lines from the rear as well as eliminate several Ork Nobs. The Ork Warboss is later killed while trying to attack Imperial lines, slaughtered along with his forces by the 19th Division's defensive lines, while the 6th Division kills any possible Ork uprisings, as well as collect samples of Ork DNA, in order to learn how the species reproduces and find a way to suppress it.


 * Retaking of Calces (722.M32-723.M32): The Zero Legion sends the 5th, 8th and 19th Division to aid the Adeptus Mechanicus in taking Calces, a lost Forge World under the rule of an Ork Warlord named Krunchmetal. The Zero Legion launch a swift bomb raid on vital areas or places with large numbers of Orks, causing devastation to the Greenskins' ranks. Afterwards the three Divisions release large numbers of platoons and squads along with Skitarii. The battle takes over three weeks, but the Division makes good progress on cleansing the Orks from Calces, thanks to the Tech-Priests and their knowledge the planet's layout. Near the end of the campaign, Krunchmetal appeared, ready to kill the Division Commander that led the campaign, assuming he was like the rest of the Space Marines he has faced. However, instead of facing him in outright battle, the Division Commander had Sicarian Ruststalkers dispatched to eliminate the Ork Warboss and his Nobz, backed up by Scout Marines, Devastators and Tactical Squads. The ambush was swift and Krunchmetal was killed along with his officers. Additional Tech-Priests soon arrived to help bring Calces back to life and into the Imperium's control, while some Zero Legionaries stayed behind the clean out the Orks completely. This marked the first time when the Adeptus Astartes of the Zero Legion, and the Adeptus Mechanicus worked together.


 * Remnants of the Auretian Technocracy (781.M32): The 12th Division was responded to an SOS from the planet Geol IV. The planet had been overrun by Chaos Space Marines from the Black Legion and apparently there were still survivors hold up in the former Planetary Governor palace. The 12th Division immediately launched strike forces via Thunderhawks supported by Stormtalons. In the beginning they encountered little resistance as the palace's defenses were still active and repelling the Chaos Marines. However some had managed to infiltrate the palace, forcing the strike force to engage them as they made their way towards the beacon. Eventually, they reached the source, only to discover a single man. The person's named was Xander Jarak, once a part of the Auretian Technocracy. He had come to the planet to recover STCs that once belonged to the Technocracy and had sent the beacon to the Zero Legion, having learned of their intentions and figured they would be perfect allies. Now under their protection, the strike force and Xander retreated back to the 12th Division Fleet, which had commenced orbital bombardment, destroying the Black Legion's forces.


 * Darthorne Crusade (818.M32): A year long campaign, the Darthorne sector had become overrun by Orks. The 4th Division had been deployed to assist the Imperial Guardsmen and PDF and neutralize the greenskins. It took a whole year to eliminate the Greenskins, followed by the extermination of their reproductive fungal spore.


 * Hunting of the Kabal (098.M33): The first known conflict between the Zero Legion and the Drukhari. The Chapter had a sent a Division to assist an Imperial Forge World against raids of an unknown Kabal. Many Tech-Priests were taken prisoners, with their forges raided. The Zero Legion assisted with reinforcing the Skitarii forces, as well as launching assaults on Dark Eldar forces, freeing hundred of prisoners. Eventually, they manage to locate where the Kabal was operating from. Preparing a strike force consisting of both Zero Legionary Veterans and Skitarri Rangers, the strike force launched an attack from the Dark Eldar's rear, destroying most of their vehicles and Webway gates. Once that was done, a frontal assault was launched, and the Kabal was completely wiped out in a few short hours.


 * Destruction of Space Hulk Spearfall (235.M33): The Space Hulk designated Spearfall, was found in Segmentum Ultima. Within the massive vessel were several warbands of Ork and Chaos Space Marines fighting one another in abandoned bloodlust, with the Space Hulk going on a direct course towards a nearby world. In order the save the planet's populace from being slaughtered by these two forces, the Zero Legion dispatched the 16th Division to eliminate the Space Hulk. The Division sent a platoon containing fully of Terminator Marines as a vanguard in order to locate critical weaknesses in the Space Hulk for the Division's ships to target in order to ensure the vessel's total destruction, while the rest of the Division arrived. The process took about a week to finish due to Spearfall's large size, as well as small skirmishes with Orks and Chaos Marines, in which half of the platoon was killed. However, their sacrifice was not in vain as they completed their mission just as the fleet arrived. The remaining Terminators were teleported onto an awaiting Escort ship, as the rest of the Zero Legion fleet destroyed the Space Hulk.


 * Quelling of the Xale Rebellion (888.M33): The Zero Legion came to aid the Hive World, Xale, from rebel forces. The rebels were personal soldiers of several noble houses that wished to overthrow the current government, having been removed from power by the same government three decades ago. The reason being was that those noble houses had abused their authority on the planet's population, and were replaced by the noble families that served the people. Seeing this as a direct insult to the Emperor's vision for mankind, the Zero Legion gladly assisted the current ruling body in putting down these rebels for good. Having earning respect for one another, the Planetary Governor of Xale allowed the Zero Legion to recruit from the planet's populace, thus signifying the world as one of the chapter's recruiting stations.


 * Atlas Blood Massacre (921.M33): Responding to a distress call from the Civilized Worlds, Atlas, the Chapter sends the 8th and 11th Division to aid the planetary forces against a large mass of Khorne cultists and elements of the World Eater Traitor Legion. Recognizing the large difference in numbers, despite technological advantage, the Zero Legion resorts to guerrilla tactics, such as ambushes, hit & run, and lightning strikes, weakening and aggravating the Chaos forces. The constant skirmishes, combined with their ever growing bloodlust, caused the World Eaters and Chaos Cultists to turn on each other, slaughtering one another in a frenzy. After five hours of observation, the Zero Legionaries and Atlas forces moved in and wiped out the remaining Chaos Forces. This was the first campaign where the chapter suffered minimal loses.


 * 4th Black Crusade (001.M34): Though arriving too late to make a difference, the Zero Legion assisted in the evacuation of El’Phanor's population while holding back the forces of Chaos for as long as they could.


 * Wolf's Legacy (083.M34): A Ghost Unit came upon a destroyed Battle Barge that had crashed on an unknown Feral World. The team, along with the Adeptus Mechanicus' forces linked with them, began exploring the Battle Barge before being assaulted by an unknown xenos species (which were later learned to be Genestealers). After repelling the xenos and setting up a forward base, the Zero Legion forces discovered that the Battle Barge was a part of the ancient Space Wolves Legion, having been felled near the end of the Horus Heresy. The unit also discovered a large number of deceased Space Wolves Legionaries, their gene-seeds still in perfect condition. Not willing to abandon the genetic legacy of fellow Space Marines, the Commander of the Ghost Unit contacted the nearest of their chapter's forces, requesting assistant in the recovery of the gene-seed. While waiting, the unit fought against more of the xenos for two weeks before a Strike Cruiser of the Zero Legion arrived, carrying reinforcements and several Physicians. Another three weeks were spent in the downed Battle Barge, as the Physicians worked tirelessly in recovering the gene-seed of the fallen Space Wolves, while their brothers and Skitarii forces neutralized any xenos that attacked them. After recovering the last of the gene-seeds, the Zero Legion's vessels destroyed the Battle Barge, taking the xenos that infested it. Afterwards they headed towards Fenris, where they gave the Space Wolves the salvaged gene-seed, earning the respect and gratitude of the Sons of Russ.


 * Battle for Titan of Pharon (119.M34): Various reports of Chaos activity on the Feral World of Pharon had drawn the Zero Legion's 1st Division to investigate. When they arrived, they were met with a warband of the Thousand Sons Traitor Legion, led by the Chaos Sorcerer, Ahriman. After the first week of fighting, Zero Legion Scout Marines discovered that Ahriman's goal was to awaken a sleeping Chaos Imperator-Class Titan, which had been damaged during the Horus Heresy. Worse, the Chaos Sorcerer had planned to merge the Titan with a Daemon of Tzeentch to turn it into a Daemon Engine. Acting quickly, the Division immediately launched a spearheaded assault towards the Titan's resting place, which was buried deep underground and thus protected by orbital bombardment. Unable to push back the large abundance of Thousand Sons Rubric Marines, backed up by Chaos Sorcerers, the Zero Legionaries instead weakened the ceiling above the Titan, thus making it vulnerable to the Division's ships. With the target now in sight, the Commander of the Zero Legion's fleet ordered a devastating orbital bombardment upon the Chaos Titan, destroying it and the Thousand Sons forces. However Ahriman and a handful of his servants escaped somehow.


 * The STC of Calex (010.M35): Information regarding the discovery of a STC on the Jungle World of Calex in the Arosian Sector, came to the Zero Legion's notice. Hoping to increase relations with the Adeptus Mechanicus, a message was sent to Mars about the discovery. As predicted, an Ark Mechanicus was dispatched with the Legion's 8th Division to Calex. What was originally a Feudal World of the Imperium, Calex fell to Orks during the Horus Heresy, and was reduced to a Jungle World under Feral Orks. Furthermore, an Iron Warrior warband was discovered on the planet, with Hereteks among them, hoping to acquire the STC for themselves. A threeway battle was initiated between the three forces that last a whole month. The Zero Legion made use of the opposing forces, making the Orks face off against the Chaos Warband while the Zero Legion struck them when weakened while the Tech-Priests searched for the STC. Near the end of the engagement, the device was located deep in Ork territory being used as an icon of worship. A strike force of veteran Zero Legion Ghost Squads and Skitarii Rangers was sent to take the STC, plunging deep through Ork forces. Though they took severe losses, the united force managed to find their prize and escape just as the Iron Warriors had arrive. With the STC recovered and the team out of harms way, the 8th Division fleet released an orbital bombardment onto the location, wiping out many of the traitors and xenos. The STC was given to the Adeptus Mechanicus, who later shared the design within with the Zero Legion, leading to the creation of the Spartan Assault Tank.


 * Hunt on Asab (531.M35): The 4th Division was pursuing Ork Freebooterz in the Asab Sub-sector for having attacked convoy groups that were needed for the reconstruction process after a devastating Warp Storm. The Orks had somehow been able to establish an outpost near the meteor cluster at the sub-sector's borders. The clash resulted in a ten month void warfare that also saw several boarding tactics with the Division working alongside the sub-sector's Imperial Navy forces. At least a third of the fleet had been lost during the conflict. The battle eventually ended when the Division located the position of the Ork Warboss. A Ghost Unit was dispatched to the Ork Battleship and assassinated the warboss before evacuating as the Battle Barge, Relentless, opened fire and destroyed the vessel


 * Fall of Hadrin (800.M35): The planet Civilized World Hadrin was undersieged by an Emperor's Children Warband led by Chaos Lord Eidolon. The 10th Division was sent to aid in repelling the Chaos Forces. However, lack of information, Chaos Cultists and pride of the Planetary Governor made it difficult for the Division to properly work. Worse, a Warp Storm was detected to consume the planet in two weeks. Thus, Division Commander Kalzar Niver decided to commence evacuation of the planet's populace. He was given aid from two sources: one being Inquisitor Stigma, who had come to recover STCs being kept by the incompetent Planetary Governor, and the other an unusual source: Craftworld Sol'cha. The Eldar had come to recover the Spirit Stones of a fallen Craftworld that fell onto Hadrin over three thousand years ago. A loose alliance was formed: The Eldar would help the Zero Legion in fending off the Emperor's Children while evacuation of the civilians and recovery of the Spirit Stones was under way. Stigma personally executed the Governor and took command over the PDF. Many losses were suffered against Eidolon's forces, but the coalition had managed to achieve their objective before the Warp Storm came.


 * Age of Apostasy (M36): The Age of Apostasy saw many battles to the Zero Legion. With the Warp Storms cutting isolating many Imperial Planets, as well as the heresy being done by Goge Vandire, the Zero Legion mobilized its entire force to keep order and stability alive. At the forefront was Commander Kane Bonsoon of the 17th Division. His tactics of swift assaults and void warfare were instrumental in putting down uprisings, stopping Dark Eldar raids, dealing with Ork WAAGHS and of course the Traitor Legions and their vile machinations. There was debate among the Covenant during this time, their belief that the folly of religion was justified, even with the coming of Sebastian Thor. Vandire's actions increased the already distrust and contempt towards the Ecclesiarchy the chapter already had. Yet Supreme Imperator Yavin Z Giger saw that there was not much they could do but offer the preacher their support.
 * Death on Izor IV: During the Apostasy, one Chaos Warband was reveling in the anarchy, the Dark Core, a rare band of heretics and traitors who worshipped the rogue Chaos God, Malice. They had spread much discord, destruction and death throughout the Imperial Worlds, taking advantage of the Warp Storm. Seeing their threat, Kane and his Division, along with elements of the 19th and 5th, traveled to the Dark Core's lastest attack, the Hive World Izor IV. Taking command of the Imperial forces, Kane led a counterattack against the warband. The battle lasted for a week when Kane was slain by the Dark Core leader, Balor the Anarchist. However, by then the Warp Storm had died down and the Zero Legion's mobile Fortress-Monstary, the Infinite Singularity, had arrived and laid waist to much of the Dark Core's fleet, forcing them to retreat. Kane's body was recovered and he was given full honors for his achievements.


 * 5th Black Crusade (723.M36): Five Divisions were dispatched to reinforce the worlds of the Elysia Sector from Abaddon's forces.


 * Betrayal and Faith (856.M36): The 18th Division was dispatched to the Hive World Bafo to assist with recent Chaos incrusions. They reorganized the Imperial Guardsman and Planetary Defense Force on the world and began pushing back Chaos cutlitsts and rogue Guardsmen. However, during the 5th Week of the campaign, the Division was attacked by their own allies. It was revealed that the entire planet had already fallen under the influence of Chaos, specifcally Malice, and the warband, the Dark Core made their appearance. Many platoons and squads were murdered by their former allies and the fleet besieged. Under the Commander's orders, the Zero Division managed to create a stronghold out of the former Planetary Governor's palace. A distress signal was sent to the Zero Legion Fortress-Monastary, while the Division held back the oncoming waves of enemies. The hold out lasted for an entire month before reinforcements from the 12th Division arrived. Focusing on what was important, Thunderhawks were dispatched to evacuate the survivors of the 18th Division. Stormtalons were used to provide cover while the Zero Legionaries boarded the transports. Once completed, the Zero Legion launched orbital bombardment, destroying Bafo and the traitors on the planet.
 * 6th Black Crusade (901.M36): The Zero Legion 5th and 8th Divisions provided aid for the evacuating Tech Priests from Forge World Arkreach.
 * Recovery of the Fellblade (221.M37): A Ghost Unit had been dispatched to investigate the Dead World Polaris. Once a Hive World, it had been one of the many planets that suffered during the Horus Heresy, abandoned after the Great Scouring. The Covenant believed that relics of the past could be salvaged from the planet. So, backed by the 17th Division, the team of Ghosts made planetfall and searched the wreckage of the planet's capital. There they discovered several Fellblade tanks, still in working condition, but their Machine Spirits weakened. Calling for extraction, the team was set upon by Ork Freebooterz that had arrived hoping to find scraps. A battle broke out between the Greenskins and the Space Marines, resulting in several deaths among the Ghosts. Reinforcements from the 17th Division eventually arrived after bypassing the Ork ships on board Thunderhawks supported by Stormtalons. The gunships laid waste to the heavy Ork armour while infantry was dropped to aid the Ghosts. With the Orks pushed back enough, the Zero Legion Space Marines secured the Fellblades and returned to their ships, quickly departing the planet, not wanting to waste more life now that their prize was secured.


 * 7th Black Crusade (811.M37): Zero Legion forces engaged in smarll skirmishes against servants of Nurgle from rotting several Imperial Worlds.


 * 8th Black Crusade (999.M37): The Zero Legion worked to protect Imperial citizens from Abaddon's forces while their ally Stigma worked with other Inquisitors to crack down the code of damnation for the Skullgather ritual Abaddon was performing.


 * 9th Black Crusade (537.M38): The Zero Legion 1st, 3rd and 10th Divisions tried to aid planets ravaged by Chaos Forces.


 * Rebellion of Basider (609.M38): The Zero Division received report of Imperial Nobility uprising on the Hive World Basider. Personal armies had killed the Planetary Governor, his staff and had gained control the planet and forced the population into labor. The 2nd Division went to reinforce the loyalists and take back Basider. Unfortunately, the chapter encountered a force dispatched from the Order of our Martyred Lady of the Adeptus Sororitas. This was the first time that the Zero Legion Chapter worked alongside the Sisters of Battle. However, it was not pleasant. The more realistic and tactical Zero Legion became annoyed by the Sisters fanatical devotion and reckless behavior, charging into battle without a second thought. And worse, uncaring of civilian causalities or forcing them into militias, instead working to protect Imperial Shrines. Eventually, the rebels were overthrown, the ringleaders captured and executed. But a conflict broke out between the Zero Legion Commander and the Battle Sister Canoness when the latter declared half of the population of Basider heretics and would be put to the torch. The people had no control over the rebels' actions and were powerless to stop them. Fortunately, an Inquisitor had arrived after hearing of the rebellion. Through lengthy investigation, the Inquisitor declared that the population of Basider were innocent and were still loyal servants of the Imperium and Emperor. The battle had left a strain relationship between the Zero Legion and Sisters of Battle.


 * Uneasy Alliance on Vex Gamma (744.M38): The Zero Legion would meet Sol'Cha once more on the planet of Vex. The Dead World was part of the Vex Sub-sector and was currently hosting a massive World Eater Warband led by the Daemon Prince Abrurax. The warband was preparing to invade the rest of the sub-sector when the 7th and 12th Zero Legion Divisions arrived. Planning to use the Dead World as the staging area to halt the warband, the Zero Legion ran into Eldar forces from Sol'Cha. Vex Gamma was in fact a Tomb World, with a massive slumbering Necron army beneath it. The Warlocks foresaw that if the warband was allowed its way, the Necrons would awaken. The Eldar planned to use a spell on the planet's core, causing it to implode, and taking the Necrons with it, but they needed time. It was Division Advocator Lavissir Tros who proposed a temporary alliance to defeat the warband and stop the Necrons from awakening. Thus began a two month long battle, where Eldar Warriors would engage shadowy hit and runs on the World Eaters, while the Zero Legion struck at them head on, to buy time for the ritual to be done. Near the end of the battle, Abrurax himself entered the battle and faced off against Tros and Farseer Amleth, the one who led the Eldar expedition. Amleth lost his life against Abrurax, but his sacrifice allowed Tros to severely wound the Daemon Prince with his Null Blade, banishing Abrurax to the Warp. Without their leader, the World Eaters were easy targets for the allies until the ritual was complete. Both the Zero Legion and Eldar managed to escape before Vex Gamma collapsed in on itself. Before the escape, Tros returned Amleth's Spirit Stone to his people.


 * Battle of Wahrheit (Unknown.M38): The Zero Legion go to provide aid for their successor Chapter, the Shadow Phantoms, against the Dark Core when the warband invaded their homeworld.


 * 10th Black Crusade (001.M39): The Zero Legion 19th Division was part of the reinforcements coming to aid the Iron Hands against the Iron Warriors and Black Legion.


 * Reclamation of the Esar Sub-Sector (515.M39):


 * 12th Black Crusade (Gothic War) (139.M41): When the Warp Storm cleared over the Gothic Sector, the Zero Legion sent over half of their Divisions, led by High Archbishop Faleus Octaras, the Zero Legion reinforced besieged worlds, aided Imperial Fleets and struck against isolated Chaos Warband Fleets. On the planet Tark, Faleus was able to slay a Bloodthirster of Khorne and push back the World Eater warband under the Chaos Lord Var'Gom.


 * Conflict on Izan (391.M41):


 * Macharian Crusade (392.M41-399.M41):


 * Corruption on Grig (532.M41): The 9th Division had been asked to provide assistance at sub-sector Grig. Numerous uprisings were happening all over and the Planetary Defense Force did not have the manpower to contain them all, and the forces on the Cardinal World Jauline refused to lend support. Led by the High Archbishop, Faleus Octaras, the Division began to suppress the rebellions while investigating the cause and discovered that populace of the Grig Sub-Sector had been forced to pay a large amount of taxes and tithes to the Cardinal on Jauline. A deeper investigation by Faelus showed that much of said money and resources were spent on beautifying the Cardinal's palace, extravagant furniture, artwork and meals, or sent to questionable sources. Faelus had begun questioning the Deacon stationed on the sub-sector capital Kalsar for a meeting with the Cardinal, when he was sniped in the head by a Vindicare Assasin. Shock and outraged, the 9th Division captured the assassin and deacon, as well as any other members of the Adeptus Ministorum, killed those who resisted. After a lengthy interrogation, the Division deemed that the Cardinal was corrupt and abusing his authority. Desiring justice for the people of Sub-Sector Grig who suffered, and avenge the hero Faelus, the 9th Division assaulted the Cardinal's palace on Jauline, killing his guards and anyone else who fought back, burnt it to the ground and ended it when the Division Commander took the Cardinal's head and placed it on the ruins of his castle. An Inquistional team from the Ordo Hereticus eventually arrived and after a deep discussion with one of the surviving deacons who had not partaken with the cardinal's criminal activities, concluded that the Zero Legion was in the right, even if it was excessive. A more through investigation was carried out while the 9th Division saved for a select few left.


 * Invasion of Ourae (669.M41): A warband of the Death Guard Traitor Legion was striking Ourae, a recruiting world of the Zero Legion. The 6th Division under Commander Welpher Macerate was sent to eliminate the traitors. Knowing full well how the Death Guard operated and their devotion to the God of Decay, Nurgle, Welpher also brought with him several veteran Physicians, including Director Physician Illoren Ghengma, for possible diseases and plagues. And as he predicted, the Death Guard had indeed created another plague in the name of their God among the people of Ourae, where victims were experiencing rotting skin and boils over their body. While the Physicians got to work, Welpher led his Division against the warband. Utilizing Devastator Squads and Tactical Squads to remove any organic infectious plantlife and other structures, as well as to gun down the enemy from a distance, Welpher also deployed Terminator Squads to strike the enemy up close, with Assault and Scout Squads providing support. The purge took over five months but eventually Illoren managed to develop a cure to the virus. However, much of the damage was done, about one-third of the populace had been killed by the virus and it would be three centuries until the areas of the planet quarantined by the Director Physician could be cured of infestation.


 * Battle of the Arogian Trade Route (708.M41): The Arogian Trade Route, used by the Arogian Sector, and located in Segmentum Tempestus, was under pirate raids conducted by Ork Freebooters. Led by a Mekboy, Fore-Armz, the Orks threatened to leave the sector in a state of ruin due to their stealing of vital supplies. The 5th Division arrived to assist the Imperial Forces in the sector. Most battles were engaged in space, while several platoons and squads were dispatched to planets in order to protect important outposts. The conflict went on for three months until Fore-Armz personally attacked 5th Division Commander Kordon's ship. Though heavily injured, the Mekboy killed Kordon, only for him to be killed by Xael Nedom, the Captain of the 5th Division at the time. The remaining Freebooters were either killed or scattered after their leader's death, and Xael was promoted to Commander of the 5thDivision.


 * Damocles Gulf Crusade (742-745.M41): All Divisions in Segmentum Ultima, under the command of Commander Varon participated in the campaign. The Zero Legion engages several Tau forces, pushing them back while recovering salvaged xeno weapons. Normally, such actions would earn the attention of the Inquisition, but Inquisitor Xarak Jarak kept any curious eyes away. From this, Railgun weaponry was born.


 * Splinter Fleet at Hagger (748.M41):


 * Infiltration of Planet Dron (750.M41): The Hive-World Dron had come under sieged by Tau Forces. The 7th Division had been dispatched to assist the Imperial forces in pushing the xenos back. But the Taus had already become to entrenched for normal tactics to work in forcing them out. A more subtle plan had to be made. Information soon came in that one of the Taus' spiritual leaders, an Ethereal, was present on Dron. The death of this figure would crumble the Taus' morale and give the Imperials a boost needed to push them back. With that in mind, a Platoon of Scout Marines, under veteran Lieutenant Arom Yul, was dispatched to infiltrate behind enemy lines to assassinate the Ethereal. The mission was a success and Lieutenant Arom shot the Ethereal from a far. With their objective complete, the 7th Division quickly launched an attack on the Tau forces while they were in shock, overwhelming them before they could even react.


 * Defense of the Boro Sector (753.M41):


 * Defense of Elran Sector (766.M41-769.M41):


 * Halo Crusade (985.M41-988.M41): The Halo Crusade was the largest campaign ever conducted by the Zero Legion. The name of said crusade was to the Halo Zone, the region beyond the Astronomican, as the crusade was focused on worlds near the edge of the Halo Zone. The purpose of the crusade was to retake various STCs and other ancient human technology either from the Dark Age of Technology or the Horus Heresy. These worlds had been untouched by the Macharian Crusade. The campaign saw the Zero Legion and the Adeptus Mechanicus battling against various forces.
 * Ork Freebooterz in Hovon Sector (985.M41): The Crusade Fleet arrived first to the Hovon Sector. There they were greeted by numerous Ork Ships, filled with bloodthirsty greenskins battling one another. A few had spotted the Imperial Forces, so the Zero Legion immediately acted first. The forward vessels let loos Melta Torpedoes, burning through the first several Ork ships without mercy. Once that was done, the macro-laser cannons were let loose upon the others, the Ork Freebooterz just now recognizing the new threat. However, their artillery did little against the Battle Barges and Striker Cruisers' Repulsion Shields, which instead returned their shells back to the greenskins. It did not take long for the fleet to eradicate the various Ork fleets, sending the surviving ships fleeing.
 * Battle of Lucidor (985.M41):
 * Greenskin Tide on Jancin IV (985.M41):
 * World Eaters on Icarus (985.M41):
 * Genestealers on the Righteous (985.M41):
 * Tomb World Jabal (986.M41):


 * Battle of the Necid Sector (989.M41):
 * Third Sphere Expansion (997.M41): All Divisions in Segmentum Ultima arrive to assist the Imperial Forces against the Tau Empire during the latter's Third Sphere Expansion.
 * Defense of Tarnis IV (998.M41): The 3rd and 15th Divisions were sent to protect Tarnis IV, a Civilized World who were fiercely against the Tau Empire. Commander Isaac took command of the Imperial Forces, utilizing the new Rail Cannons to repel Tau transports as they tried to land, causing heavy causalities for the xenos. Isaac focused on having them concentrated in a single area, preferring to have them all together than separated, aware of the technological prowess of the Tau army. Stormhawk Interceptors, Storm Ravens, and Stormtalons engaged Tau aerial forces, while bombers and gunships struck large concentrations of Tau troops, vehicles and walkers, making room for the Zero Legion's advance force to fight them. The Taus had underestimated the tactics and weaponry of the Zero Legion, which were more advanced than other Adeptus Astartes chapters they had prieviously faced. The Tau Commander tried to organize his forces but failed and was eventually slain by a squad of Terminator Marines. Their battle in space was not going well for the Tau either. Being led by Commander Olar, the Zero Legion launched boarding parties on Tau ships, slaughtering their crew while their Imperial Ships took care of the rest of the invasion fleet. The battle of Tarnis IV had ended in complete slaughter of the Tau Forces.
 * Invasion of Van'Sho (999.M41): Commander Yazir of the 20th Division and Commander Valin of the 7th Division led the invasion of Van'Sho, formerly known as Petulans, a Forge World. Pockets of resistance were still happening on the surface, consisting of Tech-Priests and Skitarii forces. The Zero Legion Fleet arrived swfitly and engaged the Tau Fleet, while launching Thunderhawks, Thunderhawk Transporters, Stormbirds and Drop Pods to the surface. The squads within the pods were led by Valin, who engaged Tau ground forces while the rest of the transports arrived, using various Space Marine squads and Dreadnoughts to assist him. He ordered Lieutenants to find pockets of Imperial forces and link up with the Zero Legion. Meanwhile, Yazir ordered Caestus Assault Rams to be launched at several nearby Tau Spacecrafts. Boarding them the squads focused on commandeering the ships, thanks to the chapter's studies of Tau technology, and fire on other xeno ships. The result was massive damage of the Tau Fleet before the squads returned to the Zero Legion fleet, after detonating the remainder of the spacecrafts. With their aerial support gone and no means of retreat, the Tau ground forces were quickly routed.


 * Third War for Armageddon (998.M41): When the Ork Warboss, Ghazhkull Thraka, launched another attack on the planet, Armageddon, the 18th Division under Commander Elzart Uriq was dispatched to aid the defenders. Under his orders, the Division focused mainly on safeguarding or recovering factories that produced war machines needed for defenders, freed prison camps and escorted convoys. One said skirmish saw Elzart fighting alongside Tu'Shan, Chapter Master of the Salamanders, protecting a large convoy heading towards the safety of a Hive City. The two fought back to back against Ork Boyz and Ork Bikers, Speed Freeks alongside their brothers.


 * Thirteenth Black Crusade (999.M41): The entire chapter was put into action when news of Cadia's destruction reached the Imperium. The Divisions, including the Zero Division, moved across the galaxy to assist Imperial forces. However as they suffered many losses during the Halo Crusade, the Zero Legion was not fully battle ready.
 * Fall of Cadia: The Segmentum Obscurus Divisions had arrived to assist Cadia's defenders against Abaddon's new Black Crusade. While the 1st and 16th Divisions assisted the ground forces on Cadia against the invaders, the 8th and 13th Divisions engaged the Chaos fleet. All four Divisions suffered heavy losses during the battles, especially against the Blackstone Fortress Will of Eternity until the Phalanx arrvied and rendered it in operable. Much of the Zero Legion's ground forces were killed when the traitors used the Blackstone Fortress as an artificial meteor and struck Cadia, and the remainder focused solely on evacuation. When escaping from the pursuing Chaos forces, Commander Gazar Vazin had several Escort ships abandoned crewed by Servitors, to serve as a shield while the rest of the fleet fled to Imperial space.
 * Destruction of Mags X: Mags X was one of the chapter's recruiting worlds, and was under sieged by a Death Guard warband led by Typhus the Herald of Nurgle. The Recruiting Outpost sent out a distress signal, resulting in the 14th Division to arrive and provide aid. But by the time they had arrived, half of the planet had been infected, with many of the population becoming Plague Zombies. Commander Jael'Ed immediately ordered for the infected terrain and zombies to be burned, unleashing waves of platoons wielding Volkite, Flamer and Melta weapons backed up by heavy armour. Jael'Ed personally fought against Typhus when the Chaos Champion tried to take the chapter's gene-seed. Though severely wounded, the Commander managed to survive and push back the Death Guard. Unfortunately, the damage to the planet was too much, forcing the Division to evacuate the remaining population and then bombard the planet from orbit.
 * Fall of Ywain: At the Hive World Ywain, a Chaos Fleet led by Abaddon himself had begun attacking the planet. Imperial Forces along with the 8th Division led the defense against the fleet. However, the sudden distortion between realspace and the immaterium caused by the Warp Storm was releasing thousands of Daemons, slowly overwhelming the defenders. Seeing no other option, a world-wide evacuation order was put into place. The Imperial Guards and Navy would oversee the evacuation, while the Zero Legion would hold back the Chaos tide. Most of the Division had been wiped out, with Commander Tryd Joraric and the Division Advocator being personally killed by Abaddon, but their sacrifice had allowed 81% of Ywain's population to safely evacuate.
 * Battle of Bachel: The planet Bachel of the Bachel sector had become the center point where many refugees from the sector and nearby sectors had been gathering, fleeing from the various Chaos Fleets. The 9th,10th and 11th Divisions had arrived to reinforce the Imperial Navy Fleet protecting the planet when a massive World Eater Fleet arrived. A great space battle took place, with the Navy and Zero Legion engaging the traitors. The 9th and 11th Divisions took most of the damage, with the former losing a Strike Cruiser and three Escort ships while the latter was suffering numerous boarding parties. the 10th Division was able to wipe out several command ships before aiding their battle-brothers. After five hours of fighting, the World Eaters were eventually wiped out, but two of the three Divisions were heavily damaged and unable to perform in any other engagements for the remainder of the Crusade. Commander Segan Byler agreed to find aid, while he lead his Division out to aid other Imperial forces.
 * Battle of Eddict Vas:
 * Space Skirmish in the Lakar Sector:
 * Raid of Stordaw:
 * Breach on the Infinite Singularity: Probably the most important event in the chapter's history, the Blackstone Fortress known as the Infinite Singularity, which served as the Zero Legion's mobile Fortress-Monastery, had never once been breached. Even when arriving to battlefields, no enemy has ever boarded the ancient craft, protected by its impressive array of weapons as well as the chapter's fleet. However during the 13th Black Crusade, protected only by the two Starforts, Crimson Guardian and Azure Guardian, plus the forces of the 3rd and 14th Divisions, the Blackstone Fortress was attacked by a coalition of Chaos Warband. Manipulated the chapter's arch-nemesis, the warband Dark Core, the various Chaos forces struck, hoping to plunder the might fortress and sacrifice the Zero Legion. The Astropaths were only able to send out a quick message for aid when the flux of Warp Storms cut them off. As the chapter's fleet under the command Void Marshal Lanx Ukor backed by Commander Jael'Ed Geo engaged with the Chaos ships, multiple boarding crafts were launched towards the Infinite Singularity. Many were destroyed by the Blackstone Fortress's guns, but those that survived rammed into the large vessel, unleashing their cargo of Chaos Space Marines and Daemons. They were immediately met with resistance from the Zero Legion's Watchmen, Zenith Guards and Servitors led by Supreme Imperator Marcus Z Baland and Sentry Warden Caxiel Eodin. Reinforcements from the 3rd Division under Commander Olar Faux arrived to provide assistance. Eventually fighting broke out in nearly every part of the Infinite Singularity with the exception of the inner areas. Innovate Constructor Roxer Machin led forces to defend the Blackstone Fortress's core from the invaders, less they destroy it. However, constant Daemons summoned by Chaos Sorcerers damaged the Blackstone Fortress enough that it was rendered immobile. At that moment the Dark Core fleet made its big push. Battering aside both attackers and defenders, they launched numerous crafts and boarded their arch-enemies home. Overlord Balor the Anarchist personally engaged Marcus in a vicious duel while the Zenith Guard under Grand General Zutaron Rubay tried to hold back the Dark Shields from attacking their Supreme Imperator by surprise. The day long battle finally ended when the Warp Storm subsided, followed by the coming of the 1st, 8th and 20th Division, as well as elements of the Indomitus Crusade led by Roboute Guilliman, the 1st Company of the Shadow Phantoms, and suprisingly the Renegade Chapter Manticores, the latter there to capture Kokabiel, a Harbinger of the Dark Core and a Fallen Angel. The sudden Imperial reinforcements pushed back the Chaos forces, forcing the Dark Core to flee and use their 'allies' as sacrificial shields. Daemons, Chaos Space Marines and Heretics were cleansed from the Infinite Singularity after five hours. However, much damage had been done to the Zero Legion. Many battle-brothers had been killed during the battle, the Infinite Singularity was still unable to move, requiring both it and the Azure Guardian extensive repair, and several Strike Cruisers and Escorts were lost. After a meeting between Guilliman and the Covenant, the Primarch left Primaris Space Marines meant for the Zero Legion, restoring much of their ranks to the chapter's relief. Having suffered less damage during the battle, Commander Olar and the 3rd Division left with the Indomitus Crusaders while the rest of the chapter reorganized itself.


 * Indomitus Crusade (999.M41-111.M41): With much of the Chapter still recovering their numbers or fortifying important worlds, the only Divisions who took part in the crusade were the 1st, 3rd, 7th, 10th, 14th, 16th and 20th Divisions. Given his history and achievements, Commander Olar Faux was named Captain-Commander, granting him total command of the mentioned Divisions. The numerous Ghost Units were also recalled and put into service for the crusade, thus Master Terminator Pharis Strog also accompanied and was placed as Olar's second.
 * Reclaiming Ossus Yin:
 * Battle over Jag:

Chapter Organisation
The Zero Legion slightly follows the Codex Astartes, but has their own variations. Instead of Companies, they have what are instead called Divisions, each one led by a Commander. While the number of marines in each Division are unknown, it is clear that each Division has its own form of combat, different from one another. Also, the Chapter possesses a Zero Division, which is in fact the Chapter's Honor Guard, led by their Chapter Master, or Supreme Imperator. Little change was made when the Primaris Space Marines were introduced, as only their gene-seed, equipment and vehicles were given to the chapter, due to a secret agreement between Primarch Roboute Guilliman, Archmagos Belisarius Cawl, and Inquisitor Xander Jarak with the Covenant.

Divisions
The fighting force of the Zero Legion is split into 21 Divisions, and are the equivalent of Companies in Space Marine Chapters. It is unknown how many Astartes are in each Division, given how there is little information on the Zero Legion. All of the Divisions can be considered Battle Companies, as the chapter does not have Divisions that act as Reserved Companies or a Scout Company. The Zero Division, however, serves as the closes thing as a Veteran Company. Each Division is led by a Commander, while the Zero Division is under the command of the Supreme Imperator. Four Divisions are each placed in one of the Segmentii, with the Zero Division and the last four positioned in Segmentum Solar.

Command
The Chapter's inner council, the Covenant, is the Zero Legion's Chapter Command, and is comprised of the highest officers within the Chapter. Led by the Supreme Imperator, these individuals are tasked with running the various areas of the chapter, each one is vital to the Chapter's survival and organization. Many of the members have positions that are the same as Codex Astartes ranks, and would normally assigned to a Captain of a standard Codex-Astartes chapter. Instead, they are given to Veteran Marines who have played the role of officers, but due to the Chapter's structure, they cannot afford to be on the battlefield constantly.
 * Supreme Imperator: The Chapter Master of the Zero Legion, he possesses full command over the entire chapter and heads the Chapter's Covenant. Unlike other Chapters, a marine that becomes the Supreme Imperator is given the name "Z" as a part of the chapter's belief of forgetting everything they once were and showing their loyalty to both the chapter and man. The Supreme Imperator is also the commander of the Zero Division, comprising of the chapter's Honor Guard.


 * Grand General: The Astarte that holds the title of Grand General shares the position of Master of the Keep. Thus the Grand General is the second-in-command of the Zero Legion, under the Supreme Imperator, the Chapter Master. If the Supreme Imperator is unable to command the chapter (either on a campaign or worse, dead) leadership of the Chapter falls to the Grand General in the Supreme Imperator's absence. They are a Marine who is a master soldier, having served in various Divisions and thus gaining countless battle experience. His skills of warfare are second only to the Supreme Imperator, showing incredible leadership, tactical knowledge and insight. Hence, why he is chosen among the other Commanders to serve as the Supreme Imperator's advisor.


 * Archivist Overseer: The title for the chapter's Chief Librarian, this Astarte is the strongest and wisest psyker among the Zero Legion. In charge in both commanding the chapter's Archivist, the Archivist Overseer is also put in command of the Librarius, located in the Infinite Singularity, the Chapter's mobile Fortress-Monastery. He also oversees any relics related to psykers and the warp recovered over the millennia. Like other high ranking positions, the Archivist Overseer is a member of the Covenant, and will also have a student whom he teaches his secrets in the event the current Archivist Overseer dies.


 * High Archbishop: Both the Reclusiarch and Master of Sanctity, the High Archbishop is High Chaplain of the chapter, it is his duty to oversee the rest of the chapter's Bishops and ensure that the morale and teachings of the chapter are passed on. Most of all, it is the High Archbishop's task to instill the teachings of the Imperial Truth to the cadets, the new recruits, of the Zero Legion, as well as for what the chapter fights for and its beliefs. He sits as a member of the chapter's Covenant.


 * Innovate Constructor: The rank for the one who is the Master of the Forge, the Innovate Constructor is charged with overseeing the operations of the Zero Legion's Fortress-Monastery, the Infinite Singularity, and the chapter's Starforts, studying and recording found technology and keeping track of discovered STCs. He is also in charge of the Chapter's Constructors, their Techmarines. A member of the Chapter's Covenant, while in many chapters the Master of the Forge is seen as an outcast by his own battle-brothers sometimes, the Innovate Constructor is a welcomed, and well-respected brother of the Zero Legion. His deep knowledge of machinery and technological lore is pivotal for the chapter's mission of recovering the powers of mankind's past, and bestowing them onto the present. In fact, past Innovate Constructors are the ones who have given birth to the advanced and unique weaponry, armor, and vehicles used by the chapter today. Because of the Innovate Constructor's responsibilities, the present one will always choose a Constructor as a student and successor, so that the Innovator's knowledge and secrets can be passed on and not lost in the event of his death.


 * Director Physician: The Astarte who becomes the Director Physician is the Chief Apothecary of the Zero Legion Chapter. The Director Physician is in charge of genetic, biological and medical related projects that are of the upmost importance to the chapter, as well as being the one that observes the chapter's gene-seed to ensure that no negative effects come upon it as well that the Zero Legion has a stable supply of gene-seed samples. Along with physical care, the Director Physician will work with the High Archbishop in ensuring that there are no mental effects on their brothers. Any new discoveries related to his field are automatically given to the Director Physician, who will focus on studying on those that he deems the most important, such as the genetics of xenos, searching for weaknesses, and developing counters for them. Always found in the Infinite Singularity, the Chapter's mobile Fortress-Monastery, the Director Physician is usually accompanied by Servitors, a group of Senior Physicians, and trusted Genetors. As with all high ranking positions, the Director Physician is a member of the Zero Legion's inner council, the Covenant.


 * Void Marshal: An Astarte that holds the rank of Void Marshal is the same as an Astarte of a Codex-chapter with the title of Master of the Fleet. Their duty is to command the Zero Legion's ships, including their Starforts, that answer to the Void Marshal. The Astarte that becomes Void Marshal is regarded of being a master in space battle from small to massive scales, as required of the one who commands the Chapter's vessels. Only the Supreme Imperator may overrule the Void Marshal's commands.


 * Lord Headmaster: A unique rank within the Chapter, the Lord Headmaster is the Master of Recruits, and holds the duty of training the Neophytes of the chapter, to ensure that they will be ready to uphold the chapter's sacred duty of helping mankind advanced towards the future. As such, the Lord Headmaster will travel to the various locations where the Chapter's forces are across the galaxy, and is rare for him to be in one place for too long. He must also, sometimes, reeducate the recruits away from the Imperial Creed, and to the Imperial Truth, to ensure that they do not become superstitious and ignorant like the rest of mankind has unfortunately become. He is also placed in charge of the outposts on various worlds where the chapter gains their recruits. Due to his position, the Lord Headmaster holds a seat at the Covenant, the Chapter's inner circle.


 * Master Exterminator: The equivalent to the Lord Executioner, the Marine who holds this title excels at at bloody close combat. They are granted powerful melee weapon and armor so that they may fight against the foes of mankind up close without fear. What differs between this rank and other chapter's Lord Executioners, is that the Master Exterminator is also in charge with commanding the Zero Legion's Ghost Unit, the chosen few who seek out the lost relics and technology of mankind, scattered throughout the galaxy as well as take on missions considered suicidal. Only the most hardened and patient Astarte may be given this title, as it carries a great responsibility onto the holder who has faced death countless times.


 * Sentry Warden: The Astarte in this position is the equivalent of a Codex Astartes-compliant chapter's Master of the Watch. The Sentry Warden is in charge of the Watchmen, Zero Legionaries that watch over the Fortress-Monastery, Infinite Singularity, whenever the Supreme Imperator is absent. Dedicated to defending the Chapter's home and main base of operations, the Sentry Warden has extensive knowledge on all types of defensive strategies, as well as other related warfares.


 * Vault Keeper: The Astarte in this position is the equivalent of a Codex Astartes-compliant chapter's Master of Relics. Working closely with the Master Exterminator, the Vault Keeper oversees the relics housed in the Chapter's mobile Fortress-Monastary. This also includes the distribution of said items with the chapter's champions and veterans. None may gain access to the Great Vault without the Vault Keeper's permission, with the exception of the Supreme Imperator.


 * Armament Administrator: The equivalent to the Codex Astartes-compliant chapter Master of the Arsenal, the one who holds the position of Armament Administrator is charged with overseeing the handling of weapons, vehicles and munitions to each Division and Watch-Fleets. Damage of items are immediately reported to him so that replacements and repairs can be done quickly.


 * Deployment Recorder: The Astarte of this position is the equivalent to a Codex Astartes-compliant Master of the Marches. This marine is to coordinate all Division deployments as well as the location of the chapter fleets. Due to the large numbers of the Zero Legions, the Deployment Recorder is accompanied by Servitors and Skull Servos to assist with the process.


 * Observance Coordinator: The Astarte of this position is the equivalent to a Codex Astartes-compliant Master of the Rites. They are charged with overseeing with the various rituals and ceremonies that take place in the Zero Legion. As the chapter follows the Imperial Truth than the Imperial Creed, the Observance Coordinator spreads the former to their fellow marines.


 * Prime Provisioner: Basically the Chief Victualler, the Prime Provisioner is given the heavy task of overseeing the movement of the Zero Legion's supply needs, particularly those pertaining to food, drink and the other personal requirements of the Chapter's Astartes and human support personnel. Given the chapter's large size, including fleets and outposts, the Prime Provisioner requires one with great mental fortitude and is normally accompanied by a group of Servitors and fellow Zero Legionaries.

Division Command
Divisions are led by Veteran Officers of the Chapter. These officers are experienced warriors in organization flexibility and technological weaponry. The many battles they have fought through as made them hardened leaders who can command their battle-brothers against any enemy, able to alter their plans at the last moment.


 * Commander: A Commander is the Astarte that leads the Divisions of the Zero Legion. Each Commander is a highly trained and skilled warrior, with centuries of experience, along with the best weaponry and armor the chapter has. Along with leading their Division, it is the Commander's sacred duty to uphold the recruitment, fighting style and care of the Division's forces and equipment. While it is not uncommon for a Commander to have been part of another Division than the one they currently command, most Commanders were a part of their Division before their promotion. Thus, they have a large level of knowledge of how their Division operates and uses each and everyone of his battle-brothers under his command effectively but can still put in their own style of warfare, leaving it to the rest of the Division to adapt. The position of when a Commander takes over a Division is put onto their knee pads.
 * Captain-Commander: A temporary position, it is used in the event that more than one Division is sent to the same campaign. One of the Commanders will be given this rank to show he will have command over the other Divisions. The one selected is a veteran with years of experience and better understanding of battle tactics.


 * Major: The rank of Major is a special rank that is basically the Master of Reconnaissance, recently added after the introduction of the Primaris Space Marines. These veteran officers command the Vanguard Space Marine Squads, consisting of covert operators who are ruthless killers. The ones who bear the title are masters of assassination, sabotage and infiltration. They are precise and merciless killers who will not hesitate to carry out their orders. They are accompanied by two Lieutenants to serve as his seconds. Given their position, they only follow orders of their Division Commander but cannont command anyone outside the Vanguard Space Marine Squads unless given permission.


 * Captain: Unlike other Chapters, the Zero Legion Captain does not command the chapter's fighting force. Instead, they are Veteran Marines who serve as sub-leaders of each Division, with each one having at least two or three Captains who answer only to the Division Commander. Captains serve as examples of what a true Astartes is, as well as officers in various areas of the Division, such as infantry movement, armour detail, airforce and so forth. Captains in Divisions usually have served in their Division for most of their lives, and thus have a good understanding of said Division's tactics and fighting style, second only to the Commander.


 * Lieutenant: Another unique rank among the Zero Legion, Lieutenants are field officers and veterans that are seen as skilled leaders of countless battles, and can command under the most intense situations. Lieutenant Legionaries command Platoons, a force that is composed of five Space Marine Squads. The squads in the Platoons can either be different types of Astartes, or the same one all together. The Lieutenant is allowed to utilize a more larger array of arsenals, ranging from melee weapons such as Chainweapons and Power Weapons, to Jump Packs, Heavy Weapons, to even Terminator Armor. Due to the forces within their Platoon, a Lieutenant is also an Astarte that has served in various squads and thus knows how to best utilize each of his battle-brothers to the best of their skills. Lieutenants are like Force Commanders in a way.


 * Sergeant: Just like with other Chapters, Sergeants command the the ten-man squads of the Divisions, and are placed into platoons led by Lieutenants. Like all officers Sergeants are hardened veterans of decades, even centuries, of combat, with vast experience and great bravery to lead his battle-brothers into battle and rise to victory against impossible odds.

Division Veterans
Selected from amongst the Chapter's most experienced Battle-Brothers, the Division Veterans are equally adept whether acting as dedicated bodyguards, fighting at the forefront of a battle, or forming the lynchpin of an immovable defence line. Division Veterans are usually deep in their Commander's counsel, their voices heard and respected on matters of strategy, morale and doctrine. Such a privileged position is earned through exceptional valour across countless campaigns. Over such a vast span of near-constant warfare, Division Veterans have learned the art of fighting with a vast array of weaponry in both ranged and close-quarters combat. They are permitted their pick of the Chapter's armoury, each Veteran wielding the armaments to which he is best attuned. In many cases, such Veterans are given the role's of leadership within their Division, like Captain, Lieutenant, Sergeant or the recently made Major. However, some are given unique positions that are just as important.
 * Division Advocator: Veteran Marines who are given the title of Division Advocator are the same as the Company's Champions of other Adeptus Astartes Chapters. They wield powerful relics of the Chapter, known as Null Swords and Bolt Shields, given powerful Arificer Armour, the Division Advocators focus on engaging enemy warlords and champions, striking important areas so that the Commanders may focus on the wider battle and command without worry.
 * Zenith Advocator: The Chapter's Champion, the Zenith Advocator is a member of the Zenith Guard, the Chapter's Honour Guard and Zero Division. Given Artificer Armour, the chosen warrior is equipped with the master-crafted Null Arms, Umbra and Noctis. They fight into battle without fear, their goal to deal powerful blows to the enemy and lessening the burden of the Supreme Imperators.


 * Ensigns: The title for what is the equivalent of an Ancient, the Legionaries assigned as Ensigns are given the duty of carrying the Chapter's battle standards, which emits a repulsion field to protect the platoons and squads surrounding it, as well as increase morale among the Ensign's battle-brothers.


 * Spotter: This rank is the variation of Master of the Signal. The Zero Legion officer (normally a Sergeant) is given the duty of contacting the bulk of the Chapter's forces during campaigns. They utilize a Vox-Caster for long-range vox-casters, capable of calling in artillery strikes and communicate between forces.

Zero Legionaries
The backbone of the Chapter, the Legionaries are basically the many rank and file Space Marines in the Zero Legion. They are trained to be best warriors that mankind has to offer, and can take on any foe before them for the defense of humanity. The Legionaries wield a variety of weapons and are in numbers, matched only by their individual strength and skills, as well as their fury and desire to uphold the duty of the Adeptus Astartes, to protecting the Emperor's people. Zero Legionaries are formed into squads commanded by Sergeants, with four squads put into platoons commanded by a Lieutenant. Depending on the Division Commander's preference, the platoon's squads may be a Battleline Squad, Close Support Squad, Fire Support Squad and Neophyte Squad, or consist of four squads of the same type.

Battleline Squads
Battleline Squads are the adamantium backbone of Zero Legion strike forces. Versatile, skilled and well-equipped, these Battle-Brothers are equally at home tearing a bloody path through the enemy's lines or digging in and securing their own. From acquiring vital strategic sites to mechanised offensives, rescue operations and kill missions, there is no task they cannot turn their talents to. The squads are each led by a Sergeant, who directs his warriors to flawlessly execute the orders of his superiors, the Lieutenants, and are sometimes split into five-Astartes sub-units called Combat Squads, so as to provide greater battlefield flexibility. These squads include the following:


 * Tactical Squads: The backbone of the chapter, the Tactical Marines are equipped to fight using a variety of ranged weapons across a broad range of combat conditions. The most numerous and strategically versatile warriors, they are flexible enough to press home an attack, or hold a position with withering firepower. Whatever the strategic challenge, battleline squads are usually equal to the task.


 * Intercessor Squads: A new Battleline Squad introduced with the Primaris Space Marines, Intercessors perform the role of standard multirole heavy infantry. They are numerous and strategically versatile warriors, being flexible enough to press home an attack, or hold a position with withering firepower. For whatever the strategic challenge they may face, the Intercessor Squads are equal to the task. Their skills lie not just with range combat, but also up close, using their strength to punch through metal and tear the enemy apart with their bare hands. They have been seen fighting alongside the Tactical Squads.


 * Breacher Siege Squads: Once part of the ancient Space Marine Legions, used for explicit purpose of acting as a vanguard assault force in the worst combat conditions imaginable and in the direst of war zones. They wore armour and wielded weapons befitting such an environment. The Chapter reintroduced this type of Space Marine during the Age of Apostasy when countless void battles were taking place. They were thus listed as a Battleline Squad.

Close Support Squad
Like many chapters, the Zero Legion consist of warriors who excel in shock and awe and close combat, With both melee and range weapons in their hands, the Zero Legions' Close Support Squads storm the enemy's battle lines and overrun their fortifications, reducing all that stand against them to butchered pieces. These squads include the following:


 * Assault Squads: The close support force of the Zero Legion, Assault Marines are equipped with Jump Packs and wield close quarter weapons. They are powerful melee fighters able to best almost any opponent in the bloody close-quarters melee fighting that is such a common feature of warfare in the late 41st Millennium. Their Jump Packs and skills of close combat make the Assault Marines excellent shock troops


 * Inceptor Squads: The Inceptors are the most swiftest and manoeuvrable of the Primaris Space Marines, they excel at surprise assaults, pinpoint strikes and beachhead clearance operations, performing the role as spearhead troops. The squads are relied to do well-coordinated and perfectly timed assault can break the back of any foe, cracking open their lines and sending the remnants of their army fleeing while their comrades surged forward in the confusion.


 * Reiver Squads: A close support combat specialists tasked for rapid infiltration and lightning assaults, the Space Marine Reivers combine stealth and assassination with violence and terror. They were welcomed among the Zero Legion during the Indomitus Crusade, their abilities to strike before disappearing a valuable asset when reclaiming worlds from Chaos and Xenos.


 * Incursor Squads: The Incursors are used for aggressive, close-quarters gun-fighting, made for swarming defended positions, attacking the flanks of spearhead assaults and taking out strategic enemy assests. Their wargear which enables them to do this have become of interest to the Zero Legion Constructors, who wish to see if they can create variants of them for future campaigns. The Incursors are used by Commanders to take out hidden targets and for recon purposes, learning about enemy positions, fortifications and other targets that could change the tide of battle.


 * Bike Squads: The Zero Legion make use of the Bike Squads primarily for reconassaince and hit & run tactics to weaken enemy forces for the slower moving but stronger firepower forces of the chapter. Other purposes are to engage fast moving enemies or put with armoured columns, serving as outriders to scout ahead for ambushes or safeguarding their armours' flanks and rears from assaults. Jetbikes are also included in these formations, making use of their hovering capabilities to outrun enemies.


 * Land Speeder Squadrons: Use of the Land Speeders by the chapter are mainly to support their infantry forces as well as provide assistance to ther armour. Other times they perform the typical roles of recon, scouting, resupplying and fast attacks. They serve as quick-response units, immediately coming to provide aid for beleagured battle-brothers or allies. The Zero Legion has also made use of them for urban warfare, their manueverability plus firepower quite impressive in the tight areas of cities.

Fire Support Squads
Since the Chapter's beginnings, the Fire Support Squads have proved their worth with overwhelming firepower. It is their duty is to annihilate the foe's heaviest armour and most deadly warriors with reaping volleys of rockets, las blasts and searing plasma. With the Zero Legion's advanced weaponry, these Battle-Brothers have proven themselves as a powerful defensive wall or a slow marching siege force. These squads include the following:


 * Devastator Squads: The Devastator Marines provide heavy support from the rear, gunning down their enemies with their fearsome firepower. This also means they give covering fire for their brothers among the Battleline and Close Support Squads, dealing with the large numbers of foes or the more heavily armoured and vehicles. Many of these marines are skilled marksman too, firing their heavy weapons from a great distance with impressive precision.


 * Aggressor Squads: A new fire support squad, the Aggressors are slow moving but powerful Space Marines wielding devastating firearm mounted gauntlets that make them equally lethal at close range. Aggressor Squads are used for assassination of prime targets, counter-battery volleys, or the destruction of enemy armour. wIth their target selection, marksmanship, and the timely application of firepower they have helped the Chapter win countless battles. Their mobility that surpasses Centurions make them better equipped for rough terrain and can decimate a high number of foes at the same time.


 * Hellblaster Squads: A combination of Leagion Space Marine Tactical Squad and Devastator Squad, Hellblasters are a new Fire Support Unit that provides close range fire support from their plasma weapons. They are specifically lethal against armoured units and vehicles, the plasma shots melting through the metal.  Due to the cooling their weapons need, only the most skilled marksman may join these squads. The only problem for the Zero Legion is that many of these Hellblasters are okay with martyring themselves. While none of them fear the death, the idea of needless sacrifice is a problem the chapter is hoping to fix.

Vanguard Space Marine Squads
Consisting solely Primaris Space Marines, the Vanguard Space Marines and the other new squads were a great welcome to the Zero Legion. Immediately taken in these new squads, the chapter has put these ruthless killers to work as a powerful vanguard force. These Vanguard Space Marines are led by the newly created position of Major, who orders the Vanguard Lieutenants, Shrouded Archivist and Helix Adepts under them. The Vanguard Space Marine Squads were placed into the Veteran Division, the Zero Division. The squads include:


 * Vanguard Infiltrator Squads: Also a Battleline Squad, Infiltrator Squads have the task of disrupting enemy communications and sabotaging targets of opportunity. Their use of confusion tactics and diverting holo-broadcasts to ensure that enemy communiques never reach their intended recipients also assist other squads, enabling them to move in with little trouble. These squads are also educated in self-sufficiency and survival techniques, with squads sometimes having their own medicae with them to recover the gene-seeds from fall brothers.


 * Vanguard Suppressor Squads: A Fire Support Squad who use Grav-Chutes or Jump Packs, the Vanguard Suppressor Squads act as a rapid response to heavily armoured enemy threats, their duty being to rapidly and aggressively occupy dominant firing positions and then watch for developing threats to the Space Marines' advance. Not even vehicle crews are safe from their firepower, as the Suppressor Squads can easily pierce through their metal plating and rend the crewmembers to pieces.


 * Vanguard Eliminator Squads: Another Fire Support Squad, Vanguard Eliminators are skilled marksman who haunt the shadows of the battlefield, seeking out high-value targets and bringing them down with pinpoint volleys of bolt rounds. Similarily, their skills can instead be used to cover spearhead assaults or swiftly cutting the legs out from under sudden enemy counterattacks. When working with other Vanguard Squads, Eliminators are given additional tasks such as switching quickly from knocking out artillery crews and enemy communications specialists, to mowing down massed foes moving to reinforce the battleline, to picking off the foe's own elite marksmen in vicious sniper-duels.

Neophyte Squads
The raw recruits of the chapter, and their future, the Neophytes are eagered ready warriors who wish to prove their worth. But until they can and are given their full Power Armour, the Neophytes serve their Divisions as a recon force or sniper support. In many cases, the recruits are assigned with squads of their experience brothers, to both support and learn from them. The squads include:


 * Scout Squads: The new recruits of the Chapter, Scouts are the young Marines who have yet been chosen to become full Astartes. Instead they serve as a recon force, moving ahead of the Division's main force and gathering intel on the enemy or possible dangers.  Other times they would be used as marksman, taking position from a distance and providing sniper fire for their battle-brothers, sometimes eliminating high-profile targets. Scout Squads are led by a Veteran Scout Sergeant. For the Zero Legion, these squads are usually placed in a platoon with other squads of more experience Space Marines. This enables them to learn from experience as they watch their elder brothers.


 * Scout Bike Squads: Like their older brothers, the Scout Bike Squads are trained to support heavy armour and initiate hit & run tactics on the enemy forces. However, the Scouts, who are less protected, are assigned missions that require infiltration rather than firepower. Going deep behind enemy lines. They do so to cause as much chaos and destruction as possible, such as destroying enemy fuel and ammunition dumps, cutting off supply lines, setting traps, and calling down orbital bombardments with pinpoint accuracy.

Veteran Squads
Those Zero Legions Battle-Brothers who distinguish themselves over decades of warfare, who work their way through the ranks of the Scout, Assault, Devastator and Tactical Squads, have earned the right to be called Veterans. Blue striped silver-helmed and equipped with specialist wargear, these are amongst the Chapter's finest warriors. With the exception of the Centurion Squads, the Terminator, Sternguard and Vanguard squads are solely part of the Zero Division. These squads include the following:


 * Sternguard Squads: Veterans of the Zero Legion, these marines have had countless battle experience over the centuries of service. Most importantly, they are masters of ranged weaponry, calling upon the chapter's firearms to lay waste to their enemies. Their arsenal consists of the range weapons of Battleline Squads and the heavy weapons of the Fire Support Squads. With the introduction of the Primaris Space Marines, some have taken to using the new ranged weapons.


 * Vanguard Squads: The opposite of the Sternguard Veterans, Vanguard Veterans are master close combatants. They will either jump into the thick of battle on Jump Packs, or charge head in first in Terminator Armour. They prefer melee weapons over range, and act as the Zero Division's shock troopers. Plus, the Vanguard Veterans have also used armoured vehicles to cover their approach so they can quickly combat their foes. Similar to the Sternguard, Vanguard Veterans have taken to use the new melee weapons of their Primaris Space Marine brothers.


 * Terminator Squads: A combination of protection and offensive might gifted to them by their Tactical Dreadnought Armour, the Terminator Squads match it with the fearsome battle skills of the wearer themselves. Wielding heavy weapons, these veterans storm the battlefield without fear, facing some of the mightiest foes, terrible odds and heavy armour, whether being from up close or from a distance. Sometimes some of these Veterans have been placed into other Divisions outside the Zero Division, to inspire their battle-brothers while on the battlefield. These armour also possess Repulsion Field and built in teleporters, making them an even fearsome foe.


 * Terminator Assault Squads: Terminators who excel solely in hand-to-hand combat, their armour and weapons make them a powerful force on the battlefield.The Zero Legion usually employ these fearsome squads in boarding actions or where the fighting is sure to be close and bloody, such as breaching enemy fortifications or combats through urban battle zones. For when in such cramped environments, where a foe cannot mass his firepower or line up his heaviest weapons, there are few who can withstand the brutal onslaught of a unit of Assault Terminators.


 * Centurion Squads: Those who are Centurions are the Space Marines who have been chosen to wield powered exoskeleton over their Power Armour. Called the Centurion Warsuit, these marines can then serve a heavy ranged fire support or close support assault role between that of a normal Astartes and a Terminator. They are given the tasks of facing large number of foes as well as heavy enemy armour or marching at the front during boarding and siege operations. For many of the Zero Legion chapter, using these formidable exoskeletons is considered a great honour. The Centurion Squads themselves are split into two subgroups: Assault Centurions who engage the foes up close in hand-to-hand combat, and the Devastator Centurions who lay waste to their enemies from afar with powerful ranged weapons.

Specialist Formations
The Zero Legions' order of battle contains several specialist formations and officer positions not present in other Space Marine Chapters:


 * Zenith Guards: The Astartes who become the Zero Legion's Honor Guards are called Zenith Guards. These veteran warriors have served in at least every Division, gaining centuries of experience and knowledge of various styles of warfare, and thus are considered the elite of the Chapter. The Zenith Guards also make up the bulk of the Chapter's Zero Division, which is commanded by the Supreme Imperator and serve as his personal bodyguards. Befitting their status, Zenith Guards wield the most advanced weaponry the Chapter has to give in the form of combi-weapons and are all equipped with a Void Messer. The Zenith Guard wear crafted helms shaped like ancient Greek Spartan soldiers of Terra's past, with single, long visors too and blue plumes.


 * Ghost Unit: The Ghost Unit is comprised of Space Marines of the Zero Legion called Ghosts, who have dedicated themselves to finding lost knowledge of man that date all the way to the Dark Age of Technology. Very few can become a Ghost, as these are Astartes that are willing to give their lives to search the unknown for missing technology, and thus are considered some of the best that the Zero Legion has to offer. They are also assigned to take on missions so dangerous that there is very little chance of coming out alive. Similar to Deathwatch Kill-Teams, the Ghosts are placed into squads of five under a Sergeant and rarely work with one another, or the rest of their chapter unless the situation calls for it. Each squad is given an Escort Ship as their own, usually a Nova-class Frigate, due to the class reputation as skilled scouting and surveillance, and is operated by Constructors, Physicians, Servitors and Tech-Priests that wish to aid them in their search. The moment an Astarte becomes a Ghost, their names is etched onto record for rememberance, as the assignments a Ghost is given are near suicidal, as they must go to where no human has been to in eons or carry out missions with small chance of survival. From distant worlds, to gigantic Space Hulks, the destination a Ghost's mission might take him is near-infinite, but worth if it, so long as they can recover the knowledge of the past so mankind can have a bright future. The one who oversees the missions of Ghost Squads is the Master Exterminator, who sits at the Chapter's Covenant. These Zero Legionaries have their silver colored power armour painted skull white, to represent their importance and stand out from their fellow brothers.


 * Watchmen: Due to the chapter's forces be scattered across the vast galaxy, it is very rare for an Astarte to be given the chance to see the chapter's mobile Fortress-Monastery, the Infinite Singularity. Even the Divisions in Segmentum Solar rarely get a view of the ancient vessel, and many who do consider it a great honor. Due to this, a select few Astartes from each Division are chosen to come to the Blackstone Fortress and serve as its protectors. These Watchmen are veterans and are entrusted to watch the Fortress-Monastery when the Supreme Imperator is away on campaigns or other matters. Though it may seem like a tedious and uninteresting task, to lose the Fortress-Monastery would be a shattering blow to the Zero Legion, and thus to the Watchmen, their post as guardians of the massive vessel is considered a great honour and responsibility. The Sentry Warden is in command of the Watchmen.


 * Instructors: Veteran Space Marines of the Zero Legion, they take on the task of overseeing the chapter's recruiting outposts on the worlds where the Zero Legion draw their recruits. This includes defending them should they come under attack. They answer to the Lord Headmaster.


 * Guardian Squad: Veteran Space Marines who are assigned to the Guardian Squads serve as their Division's Command Squads, the personal bodyguards of the Division's Commander and the Supreme Imperator. The members are hardened marines who will defend their Commander with all their strength, willing to take on impossible odds without hesitation. Each Commander can arrange the formation of their respective Guardian Squad, however the three required Marines is one of the Captains, an Ensign, Division Advocator and Physician.

Specialist Ranks

 * Bishops: The Zero Legion's Chaplains, the Bishops holds the duty of increasing the morale of the chapter's battle-brothers, as well as their Imperial allies. The Bishops are taught about the Imperial Truth, and to put the faith of Emperor's vision for Mankind into the hearts of humans, as well as to strike fear into the enemies of humanity.


 * Physicians: The chapter's Apothecaries, the Zero Legion's Physicians carry out the same duty as other Astarte Chapter Apothecaries do, tending to the wounded, recovering the chapter's gene-seed and so on. Along with those duties, Physicians also carry out the task of studying and archiving recovered archeotech and STC's related to science and biology, in order for the Physicians improve medical skills as well as develop chemical weapons against enemies of man, and countering new types of poison, no matter their origins. Physicians are given a lengthy teaching of biology and science related matters when they are fully initiated, and are to report any new findings to the Director Physician.
 * Helix Adepts: Another recent addition with the introduction of the Primaris Space Marines, Helix Adepts are battle-brothers normally assigned to Infiltrator Squads. While not fully trained Physicians, Helix Adepts are still capable of performing field medical skills during battle, providing aid to their brothers or the removing of the precious gene-seed. Their promotion to a full Physician is decided by the Director Physician.


 * Constructors: The Chapter's Techmarines, Zero Legionaries who become Constructors are highly coveted by the chapter, for it is they who can decipher the ancient archeotech that is discovered. Along with that, Constructors hold the normal duty of taking care of the chapter's vehicles, ships and weapons so that they remain in perfect condition for future battles.


 * Archivists: The title for the Chapter's Librarians, these Battle-Brothers are powerful psykers that use their abilities to aid the Chapter, both on and off the battle. The Archivist make good use of their powers in helping discover lost technology of mankind and other relics, as well as deciphering their purpose. Young Archivists will always accompany senior members, so as to better understand their powers and how to control them for the sake of the chapter and mankind.
 * Shrouded Archivists: The term used for the recently added Vanguard Librarians. Psykers who use their powers for obscuration and illusions, the Shrouded Archivists focus more on support rather than offense when assisting Vanguard Spade Marine squads.

Zero Legion Librarians
Like their fellow Astartes Chapters, the Zero Legion also maintain a Librarium of potent psykers who are highly talented and trained to master the power of the Warp at the highest levels. However, the Zero Legion refers to their Librarians as 'Archivists', based off of their responsibility of being in charge in the excavation and studying of the various lost relics and technology the chapter has discovered. Each Chapter selects its Librarians in its own way, either from seed worlds, as it does with the bulk of its Initiates. The Zero Legion select their psykers from the recruits they have gathered from their outposts on various worlds. Due to their forces being spread out across the galaxy, each Division has groups of senior and experience Archivists with them, in order to train young psykers that become Space Marines. Like with most Chapters, the Zero Legion trains and tests chosen psykers following the ancient ways laid out in the Codex Astartes. Archivists of the Zero Legion are trained in this way, and, with few minor variances, have been taught to live by the word of the Codex as well as to follow the chapter's own beliefs and combat style, so that they may better serve their battle-brothers. Zero Legion Archivists have a number of unique psychic abilities only used by the psykers of their Chapter:


 * Visions of the Past: Archivist are capable of direct visual information about an object, person, location or physical event through contact with objects or corpses. This allows them to create psychic maps in their minds, and guide their brothers to safety or locate their target.
 * Chain of Punishment: Releasing a whip of psychic energy, the Archivist can attack multiple targets at once by ensnaring all of them with the whip, killing or seriously injuring them at once.
 * Tempest Fury: Calling forth the Warp, the Archivist unleashes a powerful psychic storm. The tornado strikes the closes group of enemies and shreads them to pieces against the sharp blades of wind.
 * Wrath of Steel:  The Archivist strengthens their body and armour with a barrier of psychic energy, granting them additional protection against almost anything.

Tech-Priests
The Zero Legion have a close bond with the Adeptus Mechanicus on Mars, due to their access of technology thought lost. Many Divisions are accompanied by Tech-Priests during campaigns, where the priests would help the Constructors and Servitors keep the Chapter's armor, weapons and vehicles in perfect condition.

Servitors
The Zero Legion has a large contingency of Servitors, usually provided to them by the Tech-Priest of Mars. Many of the Servitors were genetically-engineered, others were once human, whom have committed serious crimes to mankind and that Zero Legion sees that life as a Servitor is the only punishment available. Given their dislikes for the Adeptus Ministorum, there have been rumors that some of the Servitors may in fact have been former Ecclesiarchy members, people who were about to commit an act that the Zero Legion saw as unforgivable. Due to the large usage of Servitors alone, many of the Zero Legion's servitors are slightly more advanced than normal ones, able to carry out tasks that require some intelligence, but not true sentience.

Chapter Serfs
Mortal servants are assigned to work at the Zero Legions' outposts, as well as crew members aboard their ships or their Fortress-Monastary. This enables the Serfs to interact with the planet's population when meetings are required or during recruitment. It also helps so that if the Zero Legion is called away to battle, their outposts can still be run by the Serfs. The ones at the Blackstone Fortress are screen tested if they can withstand the endless journey aboard the mobile Fortress-Monastery and are usually given the same tasks that other chapters would give them.

Chapter Beliefs and Culture
The Zero Legion believes strongly in the advancement of knowledge, progress, science and the unity of mankind. They view thing such as superstition and religion as a disease, causing humanity to become stagnate and weak. As such the Zero Legion does not follow the Imperial Creed, but instead the Imperial Truth - the secular, rationalist ideology formed by none other than the Emperor of Mankind. To the Chapter, the Emperor was not a Divine God, but instead a great man whose only desire was to bring about the prosperity and safety of his people, a belief that the Zero Legion hold closely. It is for this reason why they hold the Ecclesiarchy in contempt, as they believe that the organization is bastardizing the Emperor's image and slowly corroding all that he worked so hard to achieve for mankind.

In regards to the Adeptus Astartes, the Zero Legion believe that desires for honour and glory are nothing more than idiotic and foolish. To them, to be a Space Marine is about being self-sacrifice, to fulfill their duty and responsibility as the defenders of man, filled with determination to complete their goal. To protect the citizens of the Imperium is the ultimate achievement for the Zero Legion, and ending a battle quickly by any means necessary is the goal. Thus, the Zero Legion prefer to see things from a rational and logical point of view, and similar to the Raptor Chapter, they see the idea of charging into battle without a plan as foolhardy. While the Zero Legion Astartes do not fear death, they do not want to give their lives away needlessly, and instead rather have a well-put strategy whenever going into battle.

The Chapter also believes in self-reliance, hard work and independence. For one to be a warrior and defender of man, they must know what it takes to survive in the galaxy during this turmoil age. To be coddled and denying the truth of reality leads to foolishness and delusion. This belief is well ingrained into the Zero Legionaries, based off of that each Division has a different form of combat. Also, combining it with their belief of unity of mankind, bonds of brotherhood and comradery, makes the chapter a nigh-unstoppable fighting force.

The Zero Legion's strong belief in comradery spreads to other Space Marine Chapters. Many Divisions' Physicians (Apothecaries) have been known to extract the gene-seed of fallen Space Marines from other Chapters, found on the fields of long lost battles, aboard Space Hulks and other places. Knowing that a Chapter's gene-seed is sacred and a vital tool for the Chapter's survival, the Physicians will go to great lengths to ensure that it can be returned safely to the fallen Astartes' respective Chapter where it can be used for the next generation. The Zero Legion will also ensure that any secrets of said Chapters will not be discovered and remain said Chapter's secret. This has earned them much gratitude and respect from several Chapters, many of whom might face extinction were it not for the Zero Legion's efforts.

Lore Inheritance
Like the Blood Ravens, the Zero Legion value knowledge. Their expeditions and attempts to recover lost human tech plays a role in what the chapter calls 'Inheritance of Lore', to understand the history of mankind back during the Dark Age of Technology and before that. For the Zero Legion, ignorance is a grave sin as it causes disaster and betrayal. This is one of the reason why the Ecclesiarchy is hold in such contempt, as they neglect to understand mankind's history, corrupting it with their lies, sending humanity backwards rather than forward.

Combat Doctrine
The Chapter's primary form of warfare is the usage of their advanced technology that they have developed over the millennia. With the assistance of the Tech-Priest aiding the Constructors, all Divisions have shown an incredible number of weapons not seen since the Horus Heresy, as well as newly invented forms of war machines too. The Chapter is quite fond of using Grav-Weapons, followed by Volkite Weapons.

However, how these devices are utilized varies between each Division. The Zero Legion focuses on mastering several types of battle styles, and developing new ones whenever they face a new threat to humanity. This way, the Divisions will be able to counter whatever enemy they face during campaigns, no matter the locations. Thanks to that, the organization of each Division is flexible, capable of changing its style to better combat the enemy they are currently facing. Furthermore, newly promoted Commanders might prefer a different fighting style than what their predecessor used. While they may cause difficulties for most, Space Marines of the Zero Legion are quick to adapt to new combat tactics and command structures implamented by the Commanders, which they receive from Captains, Lieutenants and Sergeants.

In accordance to their belief of self-reliance, and independence, each battle-brother is taught to rely on both themselves and each other, to improve combat efficiency, whether a marine is fighting on their own or with their brothers. This means taking care of their own equipment, allowing the Constructors time to focus on other tasks. This also includes Division, as they are away from their Fortress-Monastery, and thus have learned to act on their own, as they cannot expect to always remain in contact with the Covenant. Such independence extends when two or more Divisions worked together. Commanders of separate Divisions can work in sync with one another, using different warfare specialties to fight any force.

Dust Ox Formation
This formation of the Zero Legion utilizes light vehicles, mainly Attack Bikes and Land Speeders. The forces would perform hit and run attacks in flat terrain. They strike at the enemy forces from several directions at once before pulling back and attacking from different areas. This is to help dwindle down the opposition and cause confusion among their ranks.

Deathwatch Services
The Zero Legion have sent Veteran Marines many times in the past to serve in the Deathwatch. Their advanced weaponry has proven a great boon for the Chamber Militant in their campaign against alien threats. Futhermore, thanks to the chapter's flexibility, Zero Legionaries have proven well adapt in working with Astartes from other chapters, despite the various cultures, tactics, beliefs, rivalries and fighting styles that each Space Marine Chapter has. This has enabled the Veterans to be fine and adjust to working with their cousins, even taking orders from them too. Their loyalty has also been valuable, refusing to abandon a Battle-Brother and remaining steadfast in the heat of battle. Multiple Veterans of the Zero Legion have earned high honors for their services in the Deathwatch.

Chapter Gene-seed
The gene-seed of the Zero Legion is unknown, and has remained a closely guarded secret of the Chapter, with only the Supreme Imperator, members of the Covenant, and the Commanders knowing. However it has been noted that the gene-seed is highly stable, given the number of Astartes the chapter has. It has been also confirmed that the Zero Legion is not a descendant of either the Blood Angels or Space Wolves, since none of the Astartes have shown signs of the Red Thirst and Black Rage that the Blood Angels and their descendants possess, nor the canine attributes of the Space Wolves are famous for.

However, an interesting fact has been noted that the Astartes of the Zero Legion possess an incredible healing factor. Many Zero Legionaries have shown to rapidly heal from serious, if not sometimes fatal wounds on many occasions, with some even able to reattached severed limbs with ease. Many Tech-Priest Genetors have been interested in studying the chapter's gene-seed, but have been met with severe refusal by the Zero Legion. Since it could risk their chance of studying more lost archaeotech and other secrets of mankind's past, the Adeptus Mechanicus have withheld their urge.

Another notable trait is that some of the Astartes possess strong resistance to the corrupting influence of the Warp. Remarkably this also includes many of the Chapter's Librarians (or Archivists), giving them an advantage against Chaos Forces. Whether this is some sort of tampering done by the chapter, or a genetic inheritance from the Chapter's unknown ancestors is a mystery that only the Zero Legion knows.

Chapter Recruitment
As the chapter does not have its own homeworld, the Zero Legion have built outposts on several human worlds, to draw in recruits from the planets' population. Many of these worlds were planets where the Zero Legion discovered lost archeotech and so uses the outpost to look for more relics as well as draw recruits from the populace. Other worlds are Imperial worlds that the Zero Legion have saved from invaders or threats from within. In return, the Planetary Governors have allowed the chapter to set up outposts on their planets, or draw up recruits from strong males on their worlds, in order to fill their ranks. Overseeing these recruits is the Lord Headmaster and Instructors. Like many other chapters, the Zero Legion have their own way of testing these potential Astartes if they are worthy to join the chapter.

Trials of Mind, Body and Spirit
The trials of the Zero Legion can vary but basically test the aspirants on their physical, mental and spiritual endurance. These tests can include learning how to operate and repair Astarte Weapons, long marches through unfriendly terrain, duels between fellow Aspirants or unarmed Adeptus Astartes and more. Either case, those who can pass these trials are welcomed as Neophytes, the next generation of Space Marines of the Zero Legion Chapter.

Chapter Worlds
Being a fleet-based Chapter, the Zero Legion have stationed outposts on several worlds to gather aspirants to become future Zero Legionaries. Along with that, they have forged alliances with several other worlds, offering protection in return for resources.

Recruiting Worlds
The Chapter has several recruiting worlds. Most of these planets are either designated as Feral, Feudal, Civilised and Hive Worlds. However, some of the planets have other classifications too. Some of these planets are:
 * Omega II (Hive World):


 * Minerva XI (Civilised World):


 * Xale (Hive World):


 * Ares (Feral World/Jungle World):


 * Gemstone-IV (Civilised World):


 * Palso (Feral World):


 * Novon (Civilised World):


 * Olipion Racs (Civilised World/Ocean World):


 * Kenal (Feudal World):


 * Idar (Feral World):


 * Malphan (Civilized World):


 * Lorax Kan (Feral World):


 * Yakan (Hive World):


 * Sarun (Feudal World/Desert World):


 * Mags X (Civilized World) (Former) (Dead World) (Current): Once a Civilised World, Mags X had gifted many recruits for the Zero Legion in the past. During the Thirteenth Black Crusade, it was attacked by a Death Guard Warband led by the Herald of Nurgle, Typhus, who deployed a powerful disase upon the world, killing most of the inhabitants. Though the Zero Legion pushed them back, the damage had been done and the planet was no longer inhabitable. Thus, the chapter evacuated the survivors and then bombarded the planet from orbit, destroying the virus and the entire world.


 * Ourae (Feudal World):


 * Goram Beta (Civilized World):

Allied Worlds
These planets are allied or affiliated with the Zero Legion. Mostly Forge, Mining, Industrial and Agri-Worlds, in return for protection, these planets provide the Zero Legion resources for their forces. Such worlds include:


 * Calces (Forge World):

Vehicle and Wargear Arsenal
Due to the Chapter's large collection of the ancient Standard Template Constructs (STC), the Zero Legion have been able to replicate and manufacture various technologies thought lost to man and joined with the arsenal of modern day war machines. Indeed, the chapter has several ancient and powerful Space Marine vehicles thought lost during the Horus Heresy, such as the various Deimos variant vehicles. Over the centuries, they have also created new types of inventions, such as new types of armour, weapons and vehicles, unique only to the chapter.

Weapons

 * Grav-Weaponry: Known also as Graviton Weapons, this ancient technology, dating back to the Dark Age of Technology, is highly used by the Zero Legion. Weapons capable of manipulating gravity itself, they can turn an opponent's mass against them, crushing it to pulp under its own weight. Shockingly useful against heavy armor enemies, the weapon turns even the best defences useless. Whether the chapter is capable of manufacturing their own, or found them among lost human worlds is unknown, but it is one of the reasons why the Adeptus Mechanicus went to great lengths to secure good relations with the chapter.
 * Graviton Blaster: The Graviton Blaster, or Grav-Blaster for short, is a new type of Grav Weaponry meant for Devastator Marines. While it still follows the same basis as all Grav-weapons, the Grav-Blaster is more powerful than the Grav-Gun and Grav-Pistol, capable of taking down even armoured vehicles. The Grav-Blaster's range is limited but, its destructive capabilities more than make up for this. Furthermore, the weapon can be charged, with longer charges being more powerful but can leave the wielder vulnerable, while shorter charges are weaker but can be fired quicker.


 * Volkite Weaponry: Recovered some time ago, the Volkite weapons, referring to a class of powerful thermal ray weapons whose technology is pre-Imperial in origin, back to the Age of Strife. These weapons possessed considerable killing power, surpassing most other armaments of their size. A blasts from Volkite Weapons were even capable of penetrating the thick ceramite plates of Space Marine Power Armour with a single concentrated shot. The workings of the volkite weapons were that they produced a deflagrating attack, in which subsonic combustion caused by a beam of thermal energy propagated through a material by thermodynamic heat transfer so that hot burning material heated the next layer of cold material and ignited it.  A Volkite Weapon's heat ray had especially devastating effect on organic matter, explosively burning flesh into ash and jetting fire. Thanks to their collected knowledge, the Zero Legion has managed to forge numerous of these weapons, providing them to the giddy and excited Adeptus Mechanicus, and closed allied Adeptus Astartes chapters too.


 * Combi-Weapons: Because the Constructors have free time on their hands, the chapter has possessed a good number of combi-weapons. These weapons are usually put into the possession of the Veterans of the Zero Legion, and the entirety of the Zero Division, the Zenith Guard wield combi-weapons of several types. Work to create Heavy Weapons variations have also been underway too.


 * Bolt Shield: A combination of a Bolter and Combat Shield, the handle of the shield is also the trigger for the Bolter. Said Bolter fires short burst shots that are effective at both short to mid-range. The shield is also quite sturdy, made from a rare ore the Zero Legion discovered.


 * Railgun : A recently made weapon, the designs were taken from studying recovered Tau weapons after the Damocles Gulf Crusade. After several tests, the Constructors were able to remake the magnetic-based weapons. Though not used as commonly as the Tau Fire Warriors do, the Zero Legion uses variants that focused on releasing powerful projectiles that can destroy small vehicles and penetrate enemy armor.
 * Rail Cannon: A large version of the railgun, the Rail Cannon was built to be used by the Zero Legion's vehicles, and are very proficient in long-range strikes or even serve as AA guns. The projectiles are extremely fast, making it nigh-impossible to dodge.


 * Cryo-Weaponry: A new addition to the Chapter's armory, Cryo-Weapons are essentially weapons that utilizes the freezing low temperatures against the enemies of man, inspired by the Space Wolves. The opposite of Flamers, the Cryo Weapons can freeze both flesh and metal to sub-zero temperatures until the target becomes brittle and fragile, and in most cases, kills the target due to the shock of the sudden drop in temperature.

 * Land Speeders:
 * Land Speeder Wraith: A new type of Land Speeder used exclusively by the Zero Legion, the Land Speeder Wraith is designed for aggresive forward assaults.

These sleek vehicles can be used to carry a passenger into the air above the maelstrom of battle. There were several different patterns of Jetbike used by the Imperium over the centuries, and the most common patterns are usually armed with some type of anti-personnel weapon such as a Heavy Bolter or a set of twin-linked Bolters that are synchronised to fire simultaneously.  Though lost to the rest of the Imperium, the Zero Legion have managed to recover the lost blueprints of these vehicles and continued reproduction for their own chapter's forces. Further construction has begun to create new variants of the Jetbike, as is the way of the Zero Legion to continue moving forward for the sake of mankind's future.


 * Centurion: The armored exoskeleton, the Centurion is highly favored by the Zero Legion. Its use for heavy firepower and enhanced close combat makes it well used by the Chapter against enemies of the Imperium and Mankind. There have been advancements among the Centurions, installing the Grav-Chutes, allowing the exoskeletons to hover over the ground and move at a quicker speed.


 * Mastodon: Also known as the Mastodon Heavy Assault Transport, it is a super-heavy assault transport that was utilised by Space Marine Legions during the Great Crusade and the Horus Heresy. The Mastodon was one of the heaviest assault transports ever used by the Legions, and was reserved for use against only the most heavily fortified of enemy positions. Being several times the size of a Land Raider, the Mastodon is a truly formidable war machine, capable of ferrying up to forty Space Marines, or twenty Marines and two Dreadnoughts through the most dangerous battlefields and protecting them from the most powerful of enemy weapons, including Titans. The Zero Legion had managed to recover some of these powerful vehicles from lost planets abandoned after the Horus Heresy. Through careful studying they were able to re-manufacture these vehicles, using them for large scale battles.


 * Striker Tank: Studying the anti-gravity plates of the Jetbikes, combined with ancient knowledge of collected Standard Template Construct has led to the creation of the Striker Battle Tank. Unique only to the Zero Legion, the Striker is a tank that hovers just several inches above the ground, enabling the vehicle more flexibility, speed and mobility than the other tanks of Adeptus Astartes chapter. The tank can be equipped with the armaments of either the Predator and/or Whirlwind vehicles, showing it also has a versatile use.


 * Spartan Assault Tank: A heavy-assault transport the Spartan is a massive vehicle, and is one of the largest ground vehicles ever used by the Space Marines of old and now by the Zero Legion today. The transport has the largest carrying capacity of all non-super-heavy vehicles, with the ability to carry 25 Space Marines and 12 Terminator Marines. The true beauty of the vehicle, however, is its engine and drive system allows it to travel at speeds much higher than that of similar-sized transports.


 * Sokar Pattern Stormbird: This super-heavy and dedicated attack lander was thought lost after the Horus Heresy. But remnants of the craft were found by Ghost Units, and with the combine teamwork of both the Constructors and Techpriests, the Stormbird was rebuilt in service of the Zero Legion, as well as its Void Shield. The chapter has made good use of the land, and its high-durability orbital capabilities, the usage as a mobile bastion or firebase.


 * Sicaran Battle Tank: Once the Imperial main battle tank and one of the most advanced armoured vehicles used by the Space Marine Legions of old, the Sicaran Battle Tank was thought lost. But the Zero Legion were able to recover many of these vehicles from long forgotten battles. Through the studies of the Constructors and Tech-Priests, slowly manufacturing of these glorious tanks have resumed, and are used rarely by the Zero Legion Divisions. The chapter was also able to revive the Sicaran Venator variant.
 * Sicaran Venator: A variant of the Sicaran Battle Tank, the Sicaran Venator was originally designed near the end of the Great Crusade, just before the outbreak of the Horus Heresy in the early 31st Millennium. This purpose-built tank destroyer was revived by the Zero Legion. Just like the Space Marine Legions, the chapter highly favors the Sicaran Venator for its unity of mobility and protection provided by its' chassis, and the potent firepower it could unleash in the form of its compact Neutron Laser Projector.


 * Fellblade: A super-heavy main tank, the Fellblade was highly advanced and was considered one of the greatest war machines during the Great Crusade. Many were lost or unusable after the Scouring and rarely used afterwards. However, the Zero Legion were able to recover the same STC used to construct them, plus existing Fellblades too. Working with the tech-priests, the chapter was able to produce a small number of the Fellblades for their own use, and provide them to allied chapters.
 * Glaive: A vartion of the Fellblade, the Glaive is built with the largest of the Volkite weaponry, the Volkite Carronade. It is used to destroy large xeno beasts and light enemy vehicles. The skilled Constructors were able to rebuild the Glaive by studying the Fellblades they recovered.


 * Rapier: What is called the Rapier is a mobile heavy weapons platform serves as a semi-automated, tracked ballistic or directed energy weapon mount. The Zero Legion managed to find several lying in ancient battlefields dating back to the Horus Heresy. Reconstructing them, the chapter now uses the Rapier for defending their outposts on recruiting worlds, protecting their bases during campaigns or sieges.


 * Neo Pattern Tactical Dreadnought Armour: Also called the Neo Pattern Terminator Armour, this former of the Terminator Armour is used exclusively by the Zero Legion. It's appearance is similar to the Indomitus Terminator Armor, but has some minor characteristics related to the advanced Tartaros Pattern Terminator Armour. The Neo Terminator Armour was the first set of armour to have a built in Repulsion Field, and maintains the durability and protectiveness of the Terminator Armour while also having increased range of movement. More precise, the boots possessed a manual operating system that lets the armor stick to the ground, enabling the wearer to not fear of loosing their footing, plus a higher resistance to explosions.


 * Dreadnought:
 * Longbow Destroyer Dreadnought: A new type of Dreadnought designed by the Zero Legion, the Longbow Destroyer Dreadnought, or Longbow Dreadnought for short, is a self-propelled artillery Dreadnought, is meant for long-range attacks. By adding siege armaments to the back of the Dreadnought, and bracers to steady the Dreadnought and for the recoil. This allows the Dreadnought's arms to be used for close range fighting too. After the Damocles Gulf Crsuade, Railgun Cannons were later used.


 * Falchion: Also known as the Falchion Super-Heavy Tank Destroyer, this super heavy tank destroyer was used by the Space Marine Legions of old. Many of them were lost during the Horus Heresy and few remain afterwards. However, like its sister variant the Fellblade, the Zero Legion managed to discover the lost art to construct these vehicles and have managed to produce enough for every Division.


 * Sabre Tank Hunter: The anti-armour variant of the Rhino, the Zero Legion managed to save some and have begun reproducing them. They later shared the designs with several Forge Worlds to create stronger bonds.


 * Storm Eagle: A heavy assault gunship that acts as a heavy tactical air support unit, the Storm Eagles were once used many times during the Great Crusade. But after the Horus Heresy their numbers diminished due to how difficult it became to build them. However, the Zero Legion were able to recover some surviving ships and replicate them, enabling the Chapter to use them once more. They make use of them for various tasks, such as long-range transport, orbital shuttle, scout and interceptors.
 * Fire Raptor: A specialized variant of the Storm Eagle, this gunship, the Fire Raptors, is a powerful force. It replaces the storage capacity of the Storm Eagle with greater ammunition stowage in order to feed the voracious appetite of its numerous weapon systems. The Fire Raptor is usually deployed as heavy support for landing Astartes transports. The Zero Legion have managed to build these crafts and using them against the foes.

Armour

 * Null Power Armour: From studying the STC in their hands, the Zero Legion have managed to create a new type of Power Armour for their marines, which they have named Null Armour. While appearing similar to the current armor worn by other Chapters, this Null (or 'Zero' Pattern) Power Armour possesses small jets on the sides of the heels, and the backpack. These mini-jet packs do not grant the wearer the ability for long-range jumps like Jump Packs of the Assault Marines, but does grant them more maneuverability. The wielder can move at faster speed without being slowed down by the armour, and perform greater leaps than the armor of old could. They also have a built in Coversion or Refractor Field to protect the wearer. In terms of appearance, the Null Power Armour appears as modified variants of either the Mark VI Corvus Power Armour, Mark VII Power Armour, and Mark VIII Errant Power Armour. The ones worn by the Zenith Guard are designed to appear as the Mark IV Maximus Power Armour, with the inclusion of the helmet looking similar to the helmets worn by Ancient Greeks from Terra and a change in the visor too.

Other Technology

 * Repulsion Field: A new type of energy shield, the Repulsion Field is designed to be a powerful defense for the Zero Legion. The force field redirects the kinetic energy of projectiles that hit it, and sends it back. This is useful for taking enemies by surprised, as they would never expect to be hit by their own attacks. The Repulsion Field is mostly attached to Terminator Armour, Dreadnoughts, and Zero Legionaries of high command, as well as their allied Tech-Priests. The chapter has also attached larger variants of the Repulsion Field to some of their ships, particularly their Battle Barges and the Gloriana-class Battleship, Resilient Advent.


 * Warp Gates: A Warp Gate is a point in realspace which is linked to another point in realspace by a tunnel through the Warp. The tunnel somehow avoids the normal disturbances of Warpspace, allowing a journey to be made within a fixed time and in perfect safety. The existence of Warp Gates represents something of a mystery, and much debate rages over whether they are natural or artificial. If artificial, then none can say who made them or for what purpose. Furthermore, some Warp Gates have been artificially enhanced, their entrances delineated by mechanical constructions whose exact function can only be guessed at. The Zero Legion have taken time and great care to study these objects, being sure to understand them as best they can. Through this, the Zero Legion have managed to equip their ships with their own Warp Gates, serving as a means to arrive to their destination with ease.


 * Warp Flash Tech: A breakthrough in the rediscovery of Warp Technology, the Warp Flash is used for short emergency jumps. It is mainly during space battles, as due to larger vessels being slower and often the target of numerous artilleries. The Warp Flash will allow the warship to briefly move through the warp from one location to another on the battlefield. This technology is still untested though, so this is only used during dire emergencies.


 * Digital Weapons: Though they are short ranged, they can be triggered to discharge potent laser blasts or jets of flame just as the enemy believes the wearer to be most vulnerable. With their strong relationship with the Adeptus Mechanicus and the Jokaero, the Zero Legion have gathered a great deal of these devices.

 * Constructor Trom Kor: A young Constructor attached to the 3rd Division in Ultima Segmentum, Trom has shown incredible skills in mechanics and technological lore. Always tinkering, Trom's ingenuity has helped the chapter many times in the past during campaign, including skirmishes with the Tau Empire. There is talk that Trom will become the next Innovate Constructor.


 * Venerable Dreadnought Garvin Malgor: Little is known about the one named Garvin Malgor, but it is heavily implied that he was one of the first battle-brothers at the Zero Legion chapter's founding. A forward kind of man, Garvin was known for his advanced thinking and taking in any situation with a calm and stern expression, not allowing his emotions to control him. It is not known when or how, but it is believed that Garvin was critically injured when slaying a Greater Daemon before being placed inside a Dreadnought. Since then, Garvin has been called many times when dire times were coming and a collected mind was needed. He was the first to be placed into a Longbow Destroyer Dreadnought, equipped with mounted Grav Cannons.


 * Venerable Dreadnought Basar Pethal: A Captain of the 15th Division during the 7th Black Crusade, Basar was grieviously wounded by Kharn the Betrayer during the named "Ghost War" when the World Eater boarded his Strike Cruiser. Mutiliated to near death, Basar was quickly put into a Dreadnought. Even to this day the Captain has not forgotton what Kharn did; not to himself but to his battle-brothers who were killed by the followers of Khorne. Chained to a strong sense of duty, Basar gladly fights alongside his younger brothers against the World Eaters whenever he can.

Chapter Relics

 * Advent Armour: A master-crafted Terminator Armour, the Advent Armour is said to have taken over a century to construct. Along with possessing the usual aspects of the Tactical Dreadnought Armour, the Advent Armour has a built in jump pack that allows the wielder to perform leaps similar to that of Assault Marines, thus granting the wearer more flexibility than normal Terminator Armour would allow. It also has a built in Repulsion field, protecting the wearer from most harm, particularly anti-infantry projectiles, plus Cyclone Missile Launchers with targeting systems that can be retracted and is near weightless thanks to gravitational technology. Due to its importance, the Advent Armour is traditionally worn by the Supreme Imperator.


 * Titan Fist: A master-crafted Power Fist, this relic has enough power that a single blow can destroy a Heretic Power Armour. In addition, it has a Grav-Gun intergrated into it, granting the wearer both powerful melee and range capabilities. The Gravity Gun is modified to fire smaller, but rapid graviton particle bolts, or charged for a more powerful blast. Given its weight, the Fist can only be worn by an Astarte wearing Terminator Armour, and thus it is traditionally paired with the Advent Armour, which is worn by the Supreme Imperator.


 * Star Hammer: A master-crafted one-handed Thunder Hammer, the Star Hammer is nearly weightless in the hands of the wielder, but when it strikes a target, it unleashes a powerful crushing blow of power onto the unfortunate target. This is due to it being designed using the plans of the Grav-weapon, allowing the wielder to alter the hammer's weight. In addition, the Star Hammer has a set of built in digital weapons that when activated, coats the hammer in flames, giving it the impression of a burning star. Due its power, the weapon is wielded by the Supreme Imperator.


 * Doom Repeller: A master-crafted Storm Bolter, this weapon fires what is called 'Ion Bolts'. These projectiles are fired at high-speed and when striking a target, release small explosions of high-energy streams of ionised subatomic particles, vaporising flesh and metal with equal ease. The force of these bolts are enough to knock down even those in Terminator Armor, if the ionised particles does not kill them first.


 * Humming Fang: This master-crafted artefact is a Lightning Claw. The blades can be retracted and released to s urprise the foe. Said blades release a low hum, the vibration increasing the blades' sharpness to that of a chainsword and better to cut through flesh and metal.


 * Defiance: A master-crafted Storm Shield, the Defiance was forged with repulsion technology, though of a weaker variant, it can form a small energy sield that can deflect all forms of projectiles that may try to harm the wielder. It also possesses a built in plasma gun, allowing giving wielder the combination of attacking and defending, a deadly combination. It is currently wielded by Commander Olar of the 3rd Division.


 * Meteor Striker: A modified Thunder Hammer, the weapon has a built in sonic generator. The resulting sonic boom when this mighty weapon strikes releases a shockwave so powerful that it can shatter exotic armor like that of Daemon-Made. It is currently wielded by Ursaru, Commander of the 13th Division.


 * Colligentes Rod: A Force Staff, the Colligentes Rod is given to the one who holds the position as Archivist Overseer. This staff greatly increases the psychic power and focus of the wielder, and is able to launch what the chapter calls Psychic Vortex. When these spheres of energy hit a target, whether an inanimate object or living being, it creates a gravitional pull that draws anything near the target towards it, crushing them before violently repelling them.


 * Thrymmatizo: A one-handed and single-edge Power Axe, the Thrymmatizo is given to the Master Exterminator. This weapon focuses its immense power into the blade, allowing it to destroy even force fields and armor, usually ending in the victim being brutally bisected.


 * Rejector: A modified Storm Shield, the Rejector absorbs the kinetic energy of whatever strikes it, making them harmless. Once fully charged, the shield will release a powerful energy blast that at full power can even damage a Land Raider. It is paired with the Thrymmatizo and given to the Master Exterminator.


 * Zero Frost: A Power Mace, Zero Frost is a unique weapon as it is releases great cold energy. When struck, the target is incased in ice that can cause them to become brittle and more suspectible to damage. It is currently wielded by Grand General Zutaron Rubay.


 * Contritio: A Power Flail, Contritio has Digital Weapons built into it that when it strikes something, will consume the target in an explosion. It is presently wielded by Void Marshal Lanx Ukor.


 * Null Arms: These master-crafted Power Weapons take on the forms of either pitch-black colored swords, axes, fists, hammers, claws or maces. The first set of these weapons were created by the revered Innovate Constructor, Udar Groger. Forged from extensive study of Wap-based entities, the anti-psychic fields of the Blanks, humans that possess the rare "Pariah Gene", combined with ancient technology, Udar finally found a way to construct weapons that could combat Chaos Daemons and other supernatural threats. Using an unnamed, and rare ore from a planet known only to the Covenant, Udar constructed the Null Arms. Combining both the disruption field of the Power Weapons, and a variant of the Blank's abilities, these Null Arms have proved lethal to psykers and Daemons, though they do not radiate the same uneasy aura as Blanks do. Due to their unique attribute, combined with the amount of work it takes to craft these weapons, the Null Arms may only be wielded by the Chapter's highest rank officers, and veterans. The pitch-black color of the material used to make these weapons is said to represent the "soullessness" that all Blanks are said to have.
 * Void Messer: The first Null Arms crafted by Udar, the Void Messers take the form of one-handed, single edge broadswords with pitch-blade blades. These swords are quite light and at the same time very sharp, capable of cutting through even the strongest of armour. Furthermore, the swords are quite flexible and can be wielded in the reverse grip, and switched back to the regular style and due to being a one-handed weapon, the wielder can use their other hand for separate tasks. This combination makes the Void Messers highly powerful weapons, and as such are wielded only by the Zenith Guard, the Zero Legion Chapter's Honour Guard, and are traditionally forged by the Innovate Constructor.
 * Null Sword: Another type of Null Arm, the Null Sword is a one/two-handed broadsword that is nearly weightless. Its sharpness is also potent, capable of cutting through both psychic beings and physical objects. Due to their potency and difficulty to craft, Null Swords are granted to the Division Advocators, the Company Champions.
 * Umbra and Noctis: A pair of single-edge and one-handed black power axes infused with the power of the Blanks. These blades are extremely potent to both flesh and warp are rendered, capable of negating/weakening psychic abilities and lethal to psychic entities like Daemons. They are wielded by the Zenith Advocator, the Chapter Champion.
 * Halo Saber: A single-edge Power Sword, the Halo Saber is extremely light yet sharp. Its near weightlessness makes it incredibly fast, allowing the wielder to cut down the enemy before they can even react. The sword is traditionally given to the Grand General, leader of the Zenith Guards.


 * Silver Cleaver: A Power Glaive that has been sharpen that it can easily cut through Eldar Armour and the bodies of the Necrons. When activated, it releases a powerful glow that is both blinding and awe-inspiring.


 * Deliverance: A Crozus Arcanum, it is a sign of office for those who hold the position of High Archbiship the Chief Chaplain of the Zero Legion. When used it releases a powerful sonic echo that caues vertigo all nearby foes, allowing the wielder to strike them while they are stunned. The relic is also connected to the wielder's built in Vox, allowing their voice to be amplified and provide encouragement to allies.


 * Grand Thunder Axe: A two-handed Power Axe, the Grand Thunder Axe lives up to its name as it can delivered powerful shockwaves of electricity, killing most whom are struck by this mighty weapon. Due to its origins as a weapon created by the first Innovate Constructor, Udar Ragber, this weapon acts as badge for the office of Innovate Constructor.


 * Kraken Guard: A special type of Mechadendrite, the Kraken Guard was constructed by the first Innovate Constructor, Udar Ragber. With blessings from the Adeptus Mechanicus, Udar placed an Artificial Intelligence within the Mechadendrite, giving the machine sentience. The Kraken Guard has eight limbs, which can be equipped with anything that the wearer needs, whether for maintaining the chapter's vehicles, self-defense, or personal use. Even if the wearer is to be injured that they cannot move, the AI housed within the Kraken Guard will protect them. Due to its incredible importance, the Kraken Guard is always given to the Innovate Constructor.


 * Spitfire: An ornate Inferno Pistol, along with acting as other Inferno Pistols are designed for, the Spitfire comes with another feature. It can fire fireballs for distance that explode upon contact, burning and melting whatever or whoever it hits. It is currently being wielded by Commander Elzart Uriq of the 18th Division.


 * Tempest Mantle: An Artificer Armor, the Tempest Mantle is an armor designed for great mobility, something mane Space Marines lack. This armor allows the wearer to move at incredible speed and reflexes equal to Eldar Banshees. Perfect for those who excel at close combat.


 * Spear of Light: A Power Spear of immense power, this relic is capable of piercing even the toughest of armor, whether they be tained Chaos-imbued Armor or Eldar Armor. Enemies who are at a distatnce are not safe, as the built in Digital Weapons in the spear can combine to fire a powerful piercing beam of light. Currently it remains in the Infinite Singularity, but in the past it was used by the fame Commander Kane Bonsoon.


 * Shadow Cloak: A specialized Cameleoline Cloak, this piece of equipment comes with the additional ability of making the wearer completely invisible, as well as covering their scent and very presence, even from psykers. As such, this hooded cloak is only worn by the most skilled of veteran Scout Marines.

Chapter Fleet
Due to their large numbers, relationship with the Adeptus Mechanicus, and collection of lost, advanced technology, the Zero Legion possess an impressive fleet to serve their forces. Many of the ships were built by the Zero Legion and Tech-Priests, while others were recovered from long lost battles and repaired to be brand new. They also include long loss battleship types thought lost during Horus Heresy, recovered and modified to modern standards, such as the Gloriana-class Battleship.


 * Blackstone_Fortress_Approaches.jpgInfinite Singularity: The mobile Fortress-Monastary of the Zero Legion, the Infinite Singularity is one of the ancient Blackstone Fortress, constucted by the mysterious Old Ones. It was found by the chapter during an unknown time at an unknown location. It is located somewhere in Segmentum Solar. Its Warp-based weapons and technology make it ideal for the mysterious chapter's mission to protect mankind and combat the enemies of humanity. Due this construct's large size, it is able to house hundreds of the Zero Legions war machines, their troops, as well as serving as the mobile fortress-monastery for the Chapter itself. Many times over the years, it has been modified to serve the Zero Legions' purposes, possessing a formidable array of void shields, and various orbital and sub-orbital weaponry, able to lay waste to entire cities and earning a dreadful reputation as a destroyer of worlds of the enemies of mankind.


 * Resilient Advent (Gloriana-class Battleship): Flagship of the Supreme Imperator. It was discovered during the Age of Apostasy. It was later repaired and outfitted with a large, more powerful version of a Gravity Cannon as its main weapon.


 * Starforts: The Chapter possesses two Ramilies-class Star Forts. They normally move alongside the chapter's Fortress-Monastery in the Segmentum Solar, but can be called to aid the chapter's forces during campaigns.

Chapter Colours
The Zero Legion primarily wear silver coloured power armour. The Imperialis or Aquila on the chest guard (when worn) is sky blue in colour, as is the shoulder pauldron trim. A sky blue coloured, open-faced squad specialty symbol is worn on the right shoulder pauldron or alternatively on the right greave (Tactical, Devastator, Assault or Veteran) which designates squad type. A gothic numeral displayed by the squad specialty symbol designates squad number. The sky blue coloured squad number on the left poleyn (knee guard) or greave indicates division number.

Chapter Badge
The Zero Legion's Chapter badge is an ancient sky blue coloured ' null ' symbol. This is representated as the number zero, with a slash through it, centered on a field of silver. In mathematics, the word null (from the ancient Germanic tongue: null meaning "zero", which is from Latin: nullus meaning "none").

Shadow Phantoms
It has been long speculated that the Shadow Phantoms Chapter is a descendant of the Zero Legion Chapter. Neither sides of denied nor confirmed this, and there is little information to give a strong answer. Nevertheless, the two chapters have strong bonds with one another. During the fated invasion of the Shadow Phantoms' homeworld Wahrheit, the Zero Legion were the ones who came to provide reinforcements in forcing the invading Chaos Forces off world. They later assisted the chapter in restoring order while the Shadow Phantoms rebuilt their forces. Since then, both chapters have worked together in several campaigns and crusades, most recently the 13th Black Crusade when the Zero Legion's mobile Fortress-Monastery, Infinite Singularity, was under sieged.

Omni Legion
Give that chapters have several things in common, it was only natural they develop a good bond with each other. Both focus on the recovery of lost technology from humanity's history, the advancement of humanity and the protection of the Imperial's people. There have been times when both the Zero Legion and Omni Legion have worked with each other in different campaigns.

Adeptus Mechanicus
Due to having access to several forms of technology thought lost, including the ancient STC, the Zero Legion have a good relationship with the Tech-Priests of Mars, who greatly desire to see these machines once more. It is not uncommon for ships of this Chapter to stop at various Forge Worlds, as well as to send to their Astartes to be trained to become Constructors. In many cases, some Tech-Priests, led by a Magos Explorator and accompanied by Skitarii forces, are given the honor of traveling with the Divisions of the Zero Legion, in order to find lost civilizations and relics of the past.

Inquisition
The relationship between the Zero Legion Chapter and the Inquisition is complex. Many Inquisitors are suspicious of the Zero Legion's origins, as well as their activities and numbers. There have been numerous investigations on the Chapter's past, but little has been recovered or was kept classified based upon orders from higher ranked Inquisitors. Nevertheless, the chapter's relationship with the Adeptus Mechanicus and several prominent Astarte Chapters have slowed down any ongoing investigations or put a stopped to them, given the Zero Legion's achievements and contributions to the Imperium.

The only two Ordos that the Zero Legion has good relationships with are the Ordo Xenos and Ordo Machinum. The Zero Legion have had many Veterans serve in the Ordo Xeno's Chamber Militant, the Deathwatch, plus supply information on already discovered Xenos or recently seens ones. For the Ordo Machinum, both sides have worked hard to locate lost human technology and bring back into the Imperium, alongside the Adeptus Mechanicus. There are even some cases where an Inquisitor of this Ordo will be allowed to travel with the Zero Legion's Ghost Unit.

Roboute Guilliman
Following the Primarch's resurrection and taking the position as Lord Commander of the Imperium, Roboute Guilliman met with the Zero Legion's Covenant along with Archmagos Cawl. What happened in that meeting is unknown, but it left the Primarch satisfied and convinced with the chapter's commitment to the Imperium and Mankind. He later supplied the chapter Primaris Space Marines to fill their ranks after the losses they suffered during the 13th Black Crusade and Halo Crusade.

Ecclesiarchy
The Zero Legion are on bad terms with the Adeptus Ministorum. They blame the organization for the stagnation of humanity, using the Imperial Creed to control the Imperium's people and drifting from the Emperor's Imperial Truth. The Chapter will rarely answer the call to defend Cardinal Worlds under the Ecclesiarchy's control, if only to protect the population. There have been also many conflicts between the two revolving around the fate of humans that were just recently under the control of xeno forces or those who have conflicting views towards the Imperial Creed. Furthermore the corruption of some high ranking members who use their positions for their own ends infuriate the Zero Legion. A primary example was the Age of Apostasy caused by Ecclesiarch Goge Vandire. The Chapter had seriously considered overthrowing the Ecclesiarchy but stood down. Another moment was the Grig Sector Conflict due to the corruption of the sector's Cardinal, which also saw the death of the famed High Archbishop Faelus Octaras at the hand of a Vindicare Assassin under the Cardinal's orders. The Zero Legion responded by killing most of the Cardinal's inner circle and taking the man's head. However, the chapter is aware of just how much influence the Ecclesiarchy has on the Imperium and the backlash if it was removed so swiftly. So for now, the Zero Legion keep their distance but retains a watchful eye.

Dark Core
The Zero Legion have held a long and bitter anmosity towards the Malice-worshipping warband, Dark Core. Dating back to the Age of Apostasy, the Chaos Warband inflicted heavy causalities on multiple worlds raising anarchy and taking advantage of the Warp Storms. Most notably, when their Chaos Lord, Balor slew Chapter Hero Commander Kane Bonsoon. After that, the Zero Legion would have many confrontations with the warband in the next few thousand years. Current Sumpreme Imperator, Marcus Z Baland, himself has stated just how dangerous this warband is, as the Dark Core care nothing for conquest, but complete mayhem.
