Omni Legion



"It doesn't matter where we come from, all that matters is we’re here and we serve our Emperor."

- Attributed to an unknown Omni Legion Battle-Brother

This Chapter's origins can be traced to the 7th Founding which occurred sometime in M34. Working primarily in the Segmentum Ultima the Omni Legion allies itself closely with the Adeptus Mechanicus, several other Adeptus Astartes Chapters, and the Adepta Sororitas Order of the Sacred Flame.

Despite their undying loyalty to the Imperium and its people the Chapter's history has made the Inquisition suspicious of their very existence. Kept at bay thanks to the influence of the High Lords of Terra and being watched closely by their Adepta Sororitas and Mechanicus allies. The Inquisition still requests frequent examinations of the Chapter which is handled by the Magos Biologis themselves, with reports from them and the Chapter's Apothecarion. Many describe them as an armed cleanup crew for the Adeptus Mechanicus. Though they search countless systems for traces of technology lost over the millennia their primary purpose is safeguarding the Imperium and it's citizens.

Founding
Early in M34 an Explorator Fleet from the Forge World of Roitheta was dispatched during one of the Forge World’s expeditions to find a potential STC. This specific mission took them to a world in the northern sectors of the Segmentum Ultima one which had oceans of pure ice and black mountains. This Dead World was designated Vintis. The fleet’s attention was drawn to it because of a faint signal, coming from one of the northern poles of the planet. It was difficult to determine what the signal was meant for as it didn’t appear to be a distress signal.

Explorator Zubayr landed on the planet’s surface and upon exiting his ship with a small force of Skitarii they were quickly overwhelmed by subzero temperatures that frosted their metal limbs. It didn’t take long to find a large metal door intended to welcome those as tall as 15 feet. It took mere hours for Zubayr to console with the door’s machine spirit, through this exchange he knew something was very wrong with this world.

Many of the details of what happened inside is undocumented in official files, if there’s any it’s possible they’re available to only the High Lords of Terra. What is known to be inside this fortress were Astartes. Within 200 stasis pods they slept. Already clad in power armour, some in Mark III and others in Mark IV. Other pieces of technology from the great heresy itself, many suits of Tartaros Terminator armour and unused Contemptor Dreadnoughts. Even a perfectly intact Gene-Seed was found in mass. One more item found inside was the one thing Explorators such as Zubayr can only pray to see once in their lifetime, an STC. Some initially thought that they had discovered the remnants of the lost IInd or XIth Legions.

Upon returning to Roitheta a small number of the Astartes were released from their pods with the Skitarii surrounding them as they stood before “Aliya”, the Fabricator-General who looked down at the confused Marines. Days of questioning proceeded as the High Lords of Terra were informed of their existence. The High Lords were told that these Astartes were created by the Forge World as a means of defense, the truth of their discovery was kept a secret. Much like the future Steel Confessors Chapter the High Lords of Terra allowed the Forge World control of this Chapter, the conditions being things such as constant reports of their actions and detailed documents of all their campaigns. Finally granting unquestioned control of the Chapter to the High Lords themselves should they deem it necessary.

During this time a larger Explorator fleet was sent back to Vintis but more properly prepared to collect everything they could with the intention of finding similar heresy era technology or perhaps something older than that. Last contact would be many months after reaching their destination. A Space Marine Chapter located in the sector was sent to investigate, the reports that returned were disturbing. The Explorator fleet’s remains were hardly husks as the ships were torn apart and gutted. Blown to pieces and everything that wasn’t the framework was gone. That wasn’t the strangest part. Vintis was also gone. Vanished. An entire planet as though it never existed.

By the time the 7th Founding neared it would be determined that the Forge World of Roithea would serve as the Chapter’s supplier for weapons and vehicles. Production for the world boomed and they received additional resources from nearby systems to aid in production ranging from a bolt pistol to mighty Battle Barges. The High Lords of Terra made the decision to have this new Chapter dubbed “The Omni Legion” operate in the Segmentum Ultima. Their primary duty begun with the pursuit of technology in the same way as the Explorators. All the while remaining on standby and prepared to go to battle at a moment's notice.

Taking a small fleet of a single Battle Barge and six Dauntless-class Light Cruiser this new Company which would eventually become the Chapter's Ist Company took to the stars to find a recruitment world that would host their Fortress-Monastery.

Tallon Prime
Hosted the Chapter and their Fortress-Monastery from the year 513.M34 to 398.M36 In the year 487.M34 the Desert World of Tallon Prime was contacted by the Omni Legion led by their first Chapter Master "Griffith" as one of the first worlds visited by the newly established Chapter. The planet is roughly 5540 km in its radii, putting it roughly 15% smaller than Holy Terra. The purpose of this was to find a world that would best suit training the Chapter’s Initiates and Tallon Prime was found.

Inconclusive reports that often conflict with one another have given different reasons for why the Chapter's original Fortress Monastery was ultimately abandoned. A notably suspicious detail is that despite the Chapter becoming fleet based later in its life the fleet that it would become known for seemed to be constructed and battle ready within a mere 3 years after the loss of their original Fortress Monastery.

One of the most popular theories is that it was overwhelmed by a swarm of dangerous lifeforms and was deemed too dangerous. The Fortress Monastery would have been swarmed by thousands of these creatures, killing anything that tried to stop them.Though these are mostly rumors. No one knows the location of the original Fortress Monastery as records pertaining to such a thing have been lost, making it difficult to prove them true or not.

The Ark
The Ark, is a massive ship capable of housing the entire Chapter, their allies and fleet of additional ships should the moment arise. Commonly known as a Ramilies-class Starfort the Mechanicus of Roitheta hold a large presence on the ship as part of the agreement between the Omni Legion and Roitheta, all technology recovered by the Chapter is to be overlooked by both Explorator Zubayr and the Chapter's Warden Dominus before it’s taken to Roitheta to ensure it’s condition and any additional research performed before it’s turned over.

The inside of this massive space fortress would appear to be an endless maze to those who have never traversed it's halls before, it takes several years of service before one becomes familiar with the paths. Companions (Serfs) of the Chapter are given their own comfortable beds in several living areas, those who serve an Omni Legion battle brother directly will share a living space with him. The closer one gets to the core of the ship the more dangers they could face unless accompanied by higher ranked Astartes. The inner sanctum of the Chapter's Reclusiam/Armorium are filled with those of the Chapter's Mechanists (TechMarines), Wardens (Chaplains) and Tech-Priests of the Mechanicus.

Typically The Ark will hold its position within the Roi Sub-Sector should it’s support be needed to defend their home. There have been reports of The Ark aiding in the support of Imperial fleets outside of their home sub-sector but such events cannot be listed here. As a mighty ship it is the command vessel of the Omni Legion's fleet, under the command of the Chapter Master.

Should the entire Chapter be dispatched to multiple campaigns they will leave the ship to their Companions with the Adeptus Mechanicus to watch over while protected by a small legion of Skitarii who’s weapons would reduce any intruders to vapor. While the Chapter may own the Starfort it is ultimately the Mechanicus of Roitheta that allow them to reside within their realm. It should be known that despite being seen as just a Fortress Monastery it is still a force to be reckoned with, even the infamous IInd Company of the Omni Legion who's known to be experts at void warfare have from time to time called upon the aid of The Ark.

The Ark's Vault
Deep within the Ark is the Chapter’s personal storage of all relics, technology and other valuables. Appropriately named the Vault. Deep within it the faint glow of Skitarii eyes can be seen once you enter, awaiting to slay any intruders who make it passed the defense or those who wander too far from their guides. The Wardens are the guardians of this place with none allowed to enter the vault without their permission. Besides members of the Mechanicus or the Chapter's Council. Most relics of the Chapter are kept here while the Captains of the Chapter guard relics unique to their Companies. It’s believed that some of these relics are taken from Renegade Chapters.

Should any intruders reach the door they'd need to pass the squad of Battle-Automata that stand at the entry. Wielding massive blades larger than even the Chapter's average Astarte, with a powerful Mauler pattern Bolt Cannon attached to their left shoulder. A shield attached to their left forearm capable of extended in size to properly protect the machine and any allies standing behind it. Instructed to guard the entrance to the Vault and kill any who are deemed a threat to the once Reclusiam and anyone inside.

Marines of the Chapter enter the Vault with a Mechanist escort once they achieve the rank of Sergeant, granted a helm from the very Vault itself.

The remains of their Dreadnoughts are kept here should they be damaged beyond repair, resting alongside those who still rest for the day where they're called to battle. It is not known how many heroes of the Imperium of man rest within these walls, what is known is that those who still simply rest for the next battle are the brightest stars of the Chapter. Ready to charge into battle once they're called upon.

Beliefs
The Omni Legion will come to the aid of those of the Imperium if they're in their desperate hour. Believing the people who swear their loyalty of the Emperor of mankind are worth protecting, the Marines of the Omni Legion would stand between a group of civilians and an Ork firing squad. Despite this the Chapter’s duty does mean that should something as sacred as an STC be involved then they must protect it at all costs, even if it means leaving the innocent or even fellow battle brothers behind to perish in battle. The Chapter would never risk the lives of a planet’s populace without attempting another method, such as attracting the attention of all the enemies or working to evacuate cities before a battle can break out.

Like many Astartes they don’t view The Emperor as a God nor worship of him as such, it is frowned upon among the Astartes. Though they don’t interfere with such worship or force their own beliefs upon other Astartes or citizens of the Imperium of man due to the risk of a religious civil war, viewing such conflicts as trivial and would do nothing but waste time and resources. The Omni Legion believes the Omnissiah as the Emperor of Mankind, thanking the Emperor for things ranging from the bolters in his hands to the very ships they stand in. As a result the Chapter's most veteran Mechanists, known as Wardens, hold the position which would typically be held by Chaplains while maintaining their role as the Chapter's greatest Techs. The light of the Astronomican is no doubt a sign of the Emperor's psychic might, thus Omni Legionaries believe that the machine spirit of each and every form of technology is purely an extension of his will.

With the rise of the new Primaris Marines it would cause the divisions between many Chapters who saw this new breed of soldiers as heretical. However this is completely different in the case of the Omni Legion who views the Primaris Marines as a gift from the Emperor. The very concept of Astartes created to be more powerful than what was before filled the Chapter with confidence, ready to fight alongside such warriors. Initially the relations between the Chapter and their new brothers was rough with many outright ignoring their Primaris brothers outside of combat and saw them as nothing more but strangers. This was strictly a result of Roboute Guilliman's rushed implementation of the Primaris Marines following the conclusion of the Indomitus Crusade.

Those in the Chapter view living the remainder of their life as a Dreadnought as a second chance to fight for the Omnissiah and therefore a blessing. Only those in either the Chapter's Ist Company or the Chapter's upper command are given this opportunity. Captain Tristan of the IVth Company is the only Captain who has retained his leadership after being sealed inside a Contemptor Dreadnought. The reason for this is only as a result of Magos Domina Mira making such a command to the Chapter, believing that Tristan was strong willed enough to still make reasonable decisions both in battle and off.

An Occulobe mutation is the leading reason why Astartes in this Chapter always wear helmets when leaving the confines of their ships but over the millennia it has become a tradition. Many believe the intent of covering their faces is because they believe their roles are to defend the Imperium and aid in it's preservation, because of that they're faceless tools made by the Omnissiah and nothing more.

The recovery of technology thought lost is a duty that can only be entrusted to ones with a deep respect for history and the discovery of knowledge, despite such a responsibility these Astartes are not permitted to strive nor pursue goals and ambitions that goes against their primary objective. Safeguarding the Imperium. Therefore it is forbidden to deny or question orders should it go against the Imperium and Humanity at large, should such a thing happen they'd be sent to the Deathwatch as a Black Shield. In addition, those who'd break this vow would be removed from the Chapter's records.

Recruitment
Recruitment for the Omni Legion comes primarily from the world of Tallon Prime. Large ancient Hive cities house the majority of the humans while the local PDFs make use of the harsh environment outside the walls to train recruits in surviving such a hostile environment. Other methods of recruitment are from offerings provided by the people from worlds the Astartes visit, these people under the belief that their child could lead a better life as one of the Astartes who saved their world.

Military schools will take on hundreds of thousands of children, many taken from the city's Slums during their infamous cleansings performed by the Arbites. None of these children are capable of remembering such events nor are they ever revealed to them. There are those children who have been sent to attend such a school, all given the same brutal training.

Within orbital facilities created by the Adeptus Mechanicus of Roitheta, members of Tallon Prime's PDFs will be charged with training these recruits. Many children are worked or beaten to death by the intense training they receive. Succumbing to starvation or sleep deprivation in the training halls, their peers punished for attempting to aid them should they collapse during drills.

Before the boys are actually taken away to train with the Omni Legion they will be subjected to examinations to determine their health, another to see how pure their genes are. Should any of them display one condition that could be a result of inbreeding then the child will instead be sent to the Schola Progenium to pursue other lives. Their family will be then investigated, once the parents are determined they will be sentenced to death. Any remaining blood related members of the family will be stripped of their status and sent to the slums. All records of the family expunged from Imperial records.

Funerals
When an Astartes Companion dies they will have their skull removed and their name will be engraved on the forehead. The skull will then be converted into one of the Chapter's Servo Skulls, many given field roles for recon and communication. Others aid the Chapter's living Companions in simple matters. Should an Astarte's personal Companion live while his master does not then he'll be given the choice to have his skull placed inside the same capsule with his master or submit to mind-cleansing to remove any former attachments before being reassigned.

After a campaign all Astartes who perished will have their funeral held in mass by the Company on board their Battle Barge, being headed by one of the Company’s Warden. If the Astarte had an Companion alive at the time of his death the Companion will be given the chance to give his eulogy, if the Companion also perished or the Marine did not have an Companion assigned to him by the time of his death the eulogy will be handled by the Company's Warden.

Astartes of the Chapter who perish will have their bodies cremated after their second Progenoid Gland is removed, their ashes then placed inside of a capsule to join the thousands of others within the Mausoleum deep within the Chapter's Fortress-Monastery.

Chapter Organisation
The Chapter’s Companions are treated well compared to the Serfs of Chapters like the Imperial Fists or Iron Hands. They aren't abused, looked down to or ignored. The role of an Companion is to provide the Space Marines or their ships with whatever they need when they need it.

During their travels they'll often catch communications from fellow Astartes or other Imperial forces that require aid. The chapter may come to assist their allies should the call be there. The sheer size of The Ark makes it possible to house several thousand more hands should a planet wide evacuation need their aid, keeping the civilians locked away from Astartes or Companions should Genestealers or similar Xenos be blending with the populace. The closest Imperial world will then be the next location to drop off the masses before the Chapter moves on.

This Chapter is divergent from the Codex Astartes, thus the Omni Legion possesses 5 Companies. A single Veteran Company, three Battle companies and the Scout Company (dubbed the Initiate Company). The IInd Company leads local Imperial Navy forces throughout the Roi Sub-Sector to defend it from Xenos and any other invaders, either they be traitors or Heretic Astartes. The IIIrd and IVth Companies are three times larger than a normal Space Marine Company, they bring the wrath of the Imperium to countless foes with greater numbers and weapons. Finally the Initiates fight alongside Guardsmen Regiments and scout out enemy installations weeks ahead of Battle Companies arriving, providing valuable information that can almost always guarantee victory.

The Ist and IInd Companies have been known to track down Renegade Chapters and execute them with extreme prejudice. Should the technology of these Renegades remain untouched by the taint of a chaos it is taken by the Omni Legion to be turned over to the Adeptus Mechanicus. Most of it finds its way back to the Forge World of Roitheta but sometimes their work is rewarded with permission to keep many weapons and armour they reclaim for the Imperium.

Initiates (Neophyte)
Unique suits of power armour are provided to the Initiates that don't need to make use of the yet-to-be implanted Black Carapace. Once the Black Carapace has been implanted into the Neophyte they will be assigned to the IIIrd or IVth Companies for one final mission, complete one campaign alongside their battle brothers and gain as much experience they can while they serve on the front lines.

Should the Captain the Company deem their performance to be underwhelming or that they don't cooperate with their squad mates well enough the Captain will force them into squads and leave them on designated Death Worlds. The intent is to ensure the Initiates learn the important of squad cohesion and lacking such skills are unacceptable. Should all five Initiates survive the next 5 year on the Death World they will then be deemed ready to graduate. Should any die then the number of Initiates who passed will be years added to the survivor's service in the Vth Company. For example, should three members of the squad die then the two survivors will spent 3 years back in the Vth Company.

Battle Brother
Astartes who complete their training in the Vth Company will finally achieve this rank, proven to be warrior of the Emperor. Once finished with their service to the IIIrd and IVth Companies in the Devastator or Assault squads the Astarte will return to The Ark to have the Progenoid Gland in their neck removed to signify their graduation. Days later they'll be assigned the role as a Tactical Marine.

With the addition of Primaris Space Marines the Omni Legion has taken it upon them to create a new Tactical unit type. Intercessor squads mixed with those who'd normally operate as a Hellblaster, these new battle brothers operate in squads of ten, Eight Intercessors and two Hellblasters. These new squads are known as Dominators. This decision has been made to ensure that squads have an extensive range of weaponry to ensure even their heavier armored foes fall to their might.

Sergeant
Squad leaders of these Astartes are granted this title because of their iron resolve and unbreakable bond with their battle brothers. Wielding a Master Crafted Weapon from the Mechanicus and donning the helm of a past brother from battles long since passed. Guiding his brothers through the forests, deserts, tundras and hell landscapes to exterminate the enemies of mankind.

Lieutenant
These Astartes operate directly under the Captain of each Company, working to relay their orders to the Company. Upon the death of the Company’s Captain a meeting of the other Captains is held to determine which Lieutenant from the Company should be made his successor. One of the duties of the Company's Lieutenants is to draw attention to any and all flaws in their Captain's strategies.

Captain
Space Marines who reach this rank are put in command of an entire Company and are expected to get results as they are accompanied by the Company's other leaders. Given the freedom to approach battle however they see fit the combat doctrines of the Captain's influence their own Companies and helps the Chapter evolve in their methods of battle. Every Captain is entrusted with a relic from The Ark, any others they claim must be returned to The Ark and placed within the Vault.

Chapter Master
The greatest of the Chapter who sees to it that mankind never falters, a master of hundreds of battle brothers that will never turn down the chance to lead from the battlefield. A tactical genius who commands fleets into battle and organizes complex campaigns, all down to each and every squad. The responsibility on his shoulders is unrivaled by any within the Chapter.

Chroniclers (1st rank Librarian)
Keeping to The Ark's inner sanctums where their role is to record the Chapter’s exploits. They spend days locked away writing miles of paperwork and working on creating the lists of bounty the Astarte’s return with on their travels. Much of their life will be dedicated to learning to keep a clear mind and focus on their tasks, this is one of the Chapter's methods of preparing Psychic acolytes before they're trained to utilize their abilities.

Librarian (2nd rank Librarian)
Trained to use the powers of the Warp these mentally trained soldiers can bend reality as though it were their plaything, lightning bolts from their fingers to bursts of flames from their eyes. Wielding Force Staves designed to help them channel their powers in powerful melee strikes they can lay ruin to foes should they enter the battlefield. It is at this point that the Chapter's Psykers are taught extensively the art of Technomancy.

Appearing alongside their non-Psyker brothers on the battlefield as part of the Company leadership they are able to guide them through any fog of war. Most Psykers within the Chapter's Librarium at this time are trained to use their abilities to alter one's state of mind, this trick is useful when making bargains with Xenos and Rogue Traders.

Librarian Dominus (Head Librarian)
Commanding everyone within the Librarium and pushing for further research of the Warp and their ways to harness its power. It is the duty of this single warrior to be an example of how one should be able to wield their psychic might. The research performed through their leadership has stockpiled for many millennia. The Chapter's method of training their Psykers is by the Librarian Dominus forcing the Chroniclers to endure powerful and terrifying visions to test their mental fortitude, even pushing them to test their psychic might against the Librarian Dominus himself.

Mechanists
Astartes of the Chapter at an early point in their career are gifted devices and tools that one would consider faulty, they will spends years attempting to repair these during any free time in their quarters. This is a minor test formulated by the Mechanicus and the Chapter's Mechanists to determine which battle brothers display an aptitude in repairing technology.

Commanding many of the Servitors belonging to the Chapter they bless and maintain the weapons and vehicles of the Companies they stand with before a battle. Spending decades learning from the Tech Priests of Mars they come back to the Chapter as beings who speak to and for the Machine Spirit. The sheer number and importance Mechanists hold in the Chapter spreads to fellow battle brothers, even the standard Omni Legion battle brother possess more knowledge of their machines than some other Chapters. It is unknown how many Brothers of the Chapter have ventured to Mars to learn of the Machine Cult, considering the importance technology holds to the Chapter it is unexpected that these numbers could far exceed expectations.

Wardens
Chosen from the Chapter's most hardened Mechanists, similar to Iron Fathers of the Iron Hands they are a combination of TechMarine with the skull faced Chaplain. The importance of the Chapter's Wardens cannot be stressed enough with their close relations to the Adeptus Mechanicus. They lead a squad of Mechanists into battle alongside the rest of the Company's command as they stand knee-deep in blood while rallying his brothers to battle. Encouraging them to fight to the death for only then is one's debt to the Omnissiah paid.

Reclusiarch
From the ranks of the Wardens one brother is chosen to tend to and protect the Chapter's relics within the Vault itself. Despite such a responsibility the Chapter's Reclusiarch is free to leave the Fortress-Monastery to aid the Praetor Dominus (Chapter Champion) in his endless quest for recovering lost technologies to expand their collection.

Warden Dominus (Master of the Forge/Master of Sanctity)
Working alongside Explorator Zubayr in the depths of The Ark he works to maintain and guard the technological discoveries made by the Chapter while providing his insight into the Machine Spirit of every vehicle owned by the Chapter. The frequency in which he leaves The Ark has been drastically cut once the Chapter took to their status as a Fleet based Chapter. He'll spend his days tending to the fleet with the aid of his own personal chosen Mechanists, only leaving the great Fortress-Monastery in service to the Machine God by aiding the Praetor Dominus.

Apothecaries
The medics of the Chapter who go into battle with their fellow Astartes to provide medical aid or extract their Gene-Seed should they fall in battle. Their primary purpose is to aid in the creation of an Astartes through their gene therapy and their Gene-Seed and organ implantation. Most assigned to the Chapter’s Apothecarion. Unlike most Apothecaries in Space Marine Chapters these Astartes make use of tools commonly found in the possession of their Mechanists, specifically their Servo-arms. The additional limbs make them more efficient field medics who are capable of tending to more than one patient at a time, even wielding chainswords with these servo-arms.

Apothecary Dominus
As master of the Apothecarion he organizes the placement and work of every Apothecary in the Chapter. Rarely leaving the confines of The Ark his role is to protect the Chapter’s Gene-Seed and lead tests for future recruits for the Chapter with the assistance of the Magos Biologis. Should the Apothecary Dominus leave The Ark he would choose to accompany the Ist, IIIrd or IVth Companies due to their tendency to explore far beyond the Sub-Sector.

Vexillarius Bearers
The flag bearers of each Company walks into battle alongside the Warden, holding high a flag that displays the very Company’s emblem and fighting alongside his brothers. Rallying his brothers alongside him to strike down the foes of mankind. The words of the Warden and the sight of the Vexillarius are enough to drive any Astartes to look death in the face as they cry out their loyalties to the Emperor and his Imperium.

Veteran Marines
Powerful soldiers from both the Ist Company. They have received centuries of battle experience through countless battles from the other Companies before they join these ranks. Trained to use all forms of combat to tackle all situations Veterans of the Omni Legion as mentioned are trusted to use the legendary Terminator armour, heavy armored and equipped with some of the deadliest weapons the Imperium has to offer.

These dedicated warriors travel the galaxy in search of the lost technologies of mankind, vowing to destroy any who would hinder their progress. Sometimes those who would surrender their treasures to the Veterans have the chance of being sparred for a time. Broken into teams of Sternguards or Vanguards depending on the mission and roles necessary to achieve victory.

Honour Guards
Honour Guards within the Chapter are free to customize their power amour as they see fit should they be given permission by their Captain. Sometimes those who are proven to be invaluable warriors are granted permission to use of Tartaros Pattern Terminator suit. Equipped with powerful blades and durable shields Honour Guard are equipped for fast movement, high defense and deadly close range capabilities. Tristan's Honour Guard utilize Indomitus Pattern Terminator Armour with additional firearms such as forearm mounted and shoulder mounted stormbolters due to the Company's focus on heavy hitting and long ranged artillery.

Praetorians
The few who survive their service to the Deathwatch serve the Praetor Dominus (Chapter Champion) and the active Explorator, all take an oath of silence on everything they see and do. These Astartes will be equipped with armour and weapons that many in their Chapter may never see or hear otherwise. Visually they're distinct from the rest of the Chapter because most of their prominent silver is replaced with red. Their task is to be an elite task force that serves the Praetor Dominus, the Mechanicus and the Ordo Machinum.

The Praetor Dominus
This one Astarte holds as much power as the Chapter Master while on the battlefield, wielding powerful relics from The Ark's vault and donned in an ancient suit of Artificer Armour that is unlike anything else in the Chapter. This crimson hero places his faith and loyalty to the Imperium on full display to everyone before him through his ancient armour decorated with markings millennia old. His purpose unlike other Chapter Champions is instead to lead the most elite Veterans of the Chapter across the Galaxy seeking technologies lost and new to ensure the Mechanicus can lead mankind's technological advancement in the absence of the Emperor.

Master of the Fleet
The proximity the Ark maintains to the Forge World of Roitheta ensures reinforcements may be called upon at any time and could arrive within days should the aid of the Starfort be required. This role isn't held to a one individual, typically the Chapter Master holds this position but should he be tasked to a campaign that takes him away from the Ark then the role will fall to the Warden Dominus.

Companions
''The Serfs of The Omni Legion are known as Companions, their duty is just like that of any other Chapter Serfs. Like the Ultramarines and Salamanders they treat their Serfs well for their duty to their Astartes masters. ''

Each Astarte once they achieve the rank of Battle Brother is assigned a Companion whose duty is to provide the Marine with a partner that cleans his quarters and armour. Bringing his meals should he be preoccupied with his own duties. Though Companions may be seen as personal slaves to some it’s far from the truth as their Space Marine seniors value them as they would any other Battle Brother. The value of the Chapter's Companions sees that they never see the battlefield.

Head Chef (Master of the Refectorium):
In charge of preparing meals for all Space Marines and other Companions on The Ark, the Head Chef has the duty of organizing all the cooks and ensuring meals get made on time. Meals are determined days in advance to suit the activities of the Marines such as the portions or what form the food should come in such as dried or paste.

Artificers
Companions whose duty is to aid the Mechanists and Adeptus Mechanicus have this title. It's very uncommon to see Companions in this role as the heavy work is handled by Servitors in the effort to carry materials, tools and assist in the repairs. However due to the necessary "human" mind needed to catalog and organize the Chapter's master crafted weapons and relics they play a major role in assisting the Mechanists in this task.

Nutrix (Medicae)
Personal aids to the Chapter’s Apothecaries, only some of the best educated Companions can become Specialists because of the knowledge needed to even understand the biology of a Space Marine. Especially now with the newly enlisted Primaris Marines.

Aids (Scribellum)
Recorders of the Chapter’s duties and developers of the Chapter’s purity seals. Assisting the Chapter’s Chroniclers in fetching research materials or tools to record. Long days and nights of keeping candles lit and ensuring the Chroniclers have ink.

Ordinator of the House
As the personal Companion to the Chapter Master it is their role to relay all commands from high ranked Astartes of the Chapter to every Companion in every role. Like many Companions they are not permitted to leave the Ark for their own safety and to ensure moral is never waned.

Combat Doctrines
"Our tactics must be diverse for our enemies are diverse"

- First Chapter Master Griffith

The Omni Legion is built upon warfare of every kind ranging from infiltrating enemy lines in order to take them out from within or leaving nothing left through overwhelming firepower. Melta and Las weaponry are the most popular weapons for the Chapter because of the Forge World of Roitheta specializing in such types. It is because of their extensive and adaptable combat prowess that each Company is trained and assigned to designated roles. The legendary Ist Company will attack the enemy through a variety of tactics learned during ones service in all other Companies.

Space Marines of the Omni Legion enjoy the sounds of music that can be heard throughout their ships, systems set up throughout the walls to play melodies meant to help Marines and Companions focus on their tasks at hand or even to help them relax. Music also plays a large role in battle as the Chapter utilizes dozens of Vox-Drones that project these sounds over large distances as a means to raise moral for allies and intimidate their foes. It works to attract the attention of the enemy, making for a great distraction so squads moving to flank can approach with ease.

Possessing many weapons thought to be either lost to time or beyond mankind's grasp the Chapter stands as a monument to the Imperium's ingenuity. A wide range of alternate weapons and vehicles are under the Chapter's command as their vast array of Mechanists work every moment of every day to salvage and construct what they can. It is because of this that many guard regiments will be the first witnesses to any new form of weaponry deployed by the Chapter, it's rumored that the Omni Legion was the first Chapter to utilize the new pattern of Land Raiders designed as the Terminus Ultra due to their extensive knowledge and experience with Las-based weaponry. Plasma weapons are not nearly as prevalent in their armory as one would expect, only the most elite of the Chapter are granted access to such an unstable and dangerous weapon.

Ist Company
The Veterans within the Company have been trained to operate various patterns of Terminator armour. Both forms of Veterans capable of tackling multiple forms of combat using different means either through tactics or equipment. The Veteran Company is the first of the entire Chapter to attempt a pure Primaris based reconstruction of their HQ, other ranks throughout the Chapter have been passed onto Primaris Marines, especially the Cult Mechanicus taught Mechanists.

Their role as agents of the Omnissiah makes their missions dangerous due to the unknown locations they travel and foes they face will be nothing but horrific. Many of the tasks performed by the Company have been willingly kept out of most records, such details reported by the Mechanicus that must detail the loss of life or destruction of worlds. Veterans face the cruel evils of the galaxy, maintaining a calm and nearly robotic demeanor while performing their duties while looking their foes in the eye. Such an important duty means that the cost of failure is too great. It is thought of that once an Astartes serves the Veteran Company they are considered a mature battle brother and they have finally succeeded in becoming one of the trans-humans that the Omnissiah himself envisioned for the Imperium. A great sense of pride is felt throughout the Company, one wouldn't suspect as such due to how they appear when deployed.

Spending the millennia scouring the galaxy for relics or lost technology they demonstrate the Chapter’s true purpose with the might of the Omnissiah's chosen. Space Hulks and seemingly abandoned Star-Forts are the primary targets of the Company during their ventures, though keeping their channels clear for communications from fellow Astartes or other forces of the Imperium.

IInd Company
With the mission to guard the Roi sub-sector these Astates have been known to operate as far as the Nephilim and Charadon Sectors. Despite the contempt many brothers may feel toward other Companies for the freedom they are provided they are determined to fulfill their role as guardians entrusted with the protection of their Sub-sector. Even if it is within the confines of such a small section of space. As such the IInd Company are the most skilled in both void based combat and boarding operations. Many fleets have disappeared because of their work...

Unlike most of the Chapter that will be willing to negotiate a temporary alliance or ceasefire with Xenos should it prove to to be purely in their benefit the members of IInd Company do not. The nature of this Company is to ensure no threat remains. Peace is never an option and they’ll slay all the enemies of mankind. Despite current relations between the Imperium and the Ynnari they refuse to work with them but they will not fire upon them for that is the will of Roboute Guilliman and presumably the Omnissiah.

Some view them as a designated cleanup crew of the Chapter through the extensive use of flamers. If the world still holds value as an Imperial world or further investigation is needed then the corpses and wounded of their foes are set ablaze, especially against the Orks whose form of reproducing is spreading their spores. Boarding teams make extensive use of Reivers who are fast to board and take over an enemy battleship while their defenses attempt to fight off Dominator teams. The IInd Company's tactics as such are far more terrifying than any other in the Chapter, putting them on the same level as Astartes such as the Carcharodons in terms of the fear they strike in the hearts of any who hear of their bloody attacks. Entire fleets unable to clearly identify themselves to the IInd Company will find themselves at their mercy, only given one standard Terran minute to convince the Astartes that they are not intruders. It is because of these ferocity that no one can say for sure they haven't slaughtered ships full of refugees who made an inaccurate Warp jump and accidentally crossed their paths. Their fleet utilizes massive harpoons known as 'Ursus Claws' used to snare and drag or capture enemy ships similar to the Carcharodons they've already been compared to.

IIIrd Company
The blunt of attacks will come from Bike Squads with the aid of Close Support squads that will drop from the sky to meet their foes with blade and bolter. Often leading the enemy into traps squads will change their tactics depending upon the foes reactions if they determine their feint attacks are no longer effective. Fire Support teams then ambushing them with artillery support.

The Company may assign borrowed Initiate squads to assist in the evacuation of civilians as a means to ensure their safety in case the defense line is broken, working to get everyone off world as quickly as possible before joining the fight.

IVth Company
Repulsors and Land Raiders tread the ravaged war zones that the Company is known for creating with their excessive firepower. Fire Support and Battleline squads blow apart any force that attempts to resist while Close Support squads pursue stragglers leaving none to tell the tale of their defeat.

The sheer number of armored support the Company possesses makes the additional Mechanists and their Servitor assistants mandatory. Many Servitors join the front lines with Astartes to carry equipment or perform mid-mission maintenance. The Mechanicus provides many Servitors to the Chapter so it's common for those in this Company to be used as fodder during full frontal assaults. Drop Pods are a typical form of deployment for those within this Company, intended to overwhelm enemies with sudden attacks from any and all directions.

Vth Company
One of the most common strategies that's utilized is the concept of 'Ghosting' which details that if the Company deems an enemy force too vast to attack they will divide into multiple squads spanning several miles. All coordinated by the commander as he organizes assassinations on enemy commanders and missions to infiltrate enemy bases and sabotage their vehicles or even steal many of their weapons and supplies.

While the Chapter maintains a large fleet this Company does not possess a Battle Barge, this is due to the Company operating in Semi-Companies, each led by the Company Lieutenant with the same number of Apothecaries assigned to each sub-company. Each Lieutenant is trusted the command of the Semi-Company and will be granted command of their own Vanguard Class Light Cruiser.

Semi-Companies of the Vth Company will often be deployed weeks ahead of both the IIIrd Company and the IVth Company to gather in Company before the bulk of forces arrive. Other uses of the Initiate squads is to assist friendly Imperial forces, aiding in evacuations or supporting the Guard.

Meanwhile the Company's Captain leads a force of Vanguard squads across the Segmentum to either aid the Chapter itself, the Astra Militarum or other forces of the Imperium. Infiltrators and Eliminators have proven to be dangerous and valuable soldiers that can turn the tide of an entire campaign.

Order of the Omnissiah
This group's actions are mostly unknown to even the Chapter's Captains, most battle brothers will never see the Praetor Dominus let alone a member of the Brotherhood. The crimson armour of any Praetorian is the sign that they have been recognized by the Omnissiah through their exploits and the honour they bring to the Chapter. It is even rumored that any Praetorian carries more power and authority than some of the Chapter's Captains who are left in the dark of their actions.

Their personal history isn't the only thing that they chase, technology that can push humanity forward and ensure their place as the dominate species will always entice the Omnissiah's chosen. Even if it must come from a species thought to be lesser than Humans such as the Tau or Aeldari. The Ordo Xenos has crossed paths with the Sons of the Omnissiah as both groups seek knowledge and technology of Xenos origin. Even Inquisitors of the Ordo Machinum will have their chance to command the Praetor Dominus and his brothers as they scour the Galaxy for technologies once thought lost to the Imperium.

Order of Battle (as of 111.M42)
The leaders of the Chapter plan and discuss future campaigns for the Chapter from The Ark, a council between the Captains of each the Companies and the Masters of all specialist groups. Located in the heart of the massive Fortress Monastery is the Chamber of the Lords. They sit at a large table to discuss the future of the Chapter. Even the ancient Explorator Zubayr who discovered the Astartes holds a place in the Chapter's higher ranks alongside Magos Domina Mira. Mira uses her Mechanicus servitors to guide Tristan's sarcophagus to this Chamber so he may take part in such meetings.

Each Brother may be assisted in missions by a Servitor, assigned to carry extra ammunition or attachments for weapons. An Initiate will not be permitted the use of one to teach them proper discipline as part of their training. Additional Battle fitted Servitors accompany each Company as both reinforcements and disposable infantry intended to cause as much damage to the enemy as possible before they fall. Under the command of the Company Captain, Lieutenants and Mechanists. The Omni Legion seems to possess far more Servitors than most Chapters, capable of utilizing them as first wave troops in planet side assaults to soften the enemy and spend their ammunition before the Astartes engage.

Gene-Seed
''The physical appearance of the Astartes is relatively average with a lighter skin tone and dark but cloudy eyes. The average height is much larger than most Astartes, putting them closer to the new Primaris Marines. Despite these mutations their Gene-Seed has been considered stable with the same average success rate as other Chapters such as the Ultramarines or Dark Angels.''

Genetic Idiosyncrasies/Mutations
After being rediscovered by the Imperium there have only been 2 notable mutations to their Gene-Seed found after thorough tests and examinations. Records are kept close to the Adeptus Mechanicus and the High Lords of Terra as all further research and tests are carried out even in the modern age. Once an Astarte completes his service in both the Assault and Devastator squads the Progenoid Gland in his neck will be extracted before joining the ranks of the Chapter's Tactical squads. Originally this was due in part to the Chapter's smaller size and therefore Gene-Seed was more valuable, now it has become tradition and removal of the first Progenoid Gland is seen as a graduation to greater heights.
 * 1) The Occulobe:  Astartes of this Chapter are very sensitive to ultraviolet rays, when leaving their ships they are to keep their helmets on at all times to ensure they don’t get irritated. It won’t cause any permanent damage but it’ll make it difficult for the Marine to see anything unless they have something to help block those rays. Their eyes have a dark but cloudy appearance.
 * 2) The Ossmodula: Astartes with this mutations average a height of 8 feet, the larger and thicker bone structure makes the Astartes much more resistant to damage very similar to the Black Dragons. Though unlike those of the 21st Founding the Omni Legion Astartes don't appear to show any signs of bone protrusions. Custom designed power armour is developed for these Astartes due to their size, based off the designs used by the original 200.

DeathWatch Service
Veterans of the Ist Company will be picked to join the DeathWatch, serving their vigils with Watch Fortresses "Prescience" or the "Eye of Damocles". Most commonly the members of the Chapter that join the Deathwatch are Astartes trusted with the use of Melta or Las-weaponry due to their experience with such.

Should a brother survive his service in the Deathwatch their skills will put to use as a Praetor, one of the Chapter's most elite warriors. Tasked with the most dangerous missions that more times than not will see to them put through dangers rivaled only by that of the Deathwatch they served.

Ultramarines
They're not fond of the Ultramarines’ strict and aggressive nature toward anyone who doesn’t strictly adhere to the strictures of the Codex Astartes. The Ultramarines often tends to pry into the Omni Legion’s work often, especially when they are near the borders of Ultramar during their campaigns. Despite this the sheer number of successor Chapters they have and the proximity to Ultramar would be a fool's decision not to ally themselves with the thirteenth First Founding Chapter.

After the return of Roboute Guilliman and the rise of the Primaris Space Marines, the opinion of the Ultramarines became rocky because of the forceful introduction of the Primaris Marines, though the aid they provided has helped the Chapter. Despite this the Omni Legion doesn't care for Roboute Guilliman himself.

Salamanders
Relations between the Salamanders and the Omni Legion has always been great because of their similar outlook on their Serfs and the Imperium’s citizens. The Chapter sometime lends aid to the Salamanders if they believe they’re close to finding one of the Artefacts of Vulkan, though this has never truly yielded results. Working with the Salamanders has become one of the greatest honors among the Omni Legion.

The Second Company of the Omni Legion, due to their more common use of Melta and Flamer weapons, work best with the Salamanders in actual combat. In battle, fighting side-by-side, the flames wash over the Astartes armour. Despite their more aggressive tactics the very idea of fighting along the sons of Vulkan keeps the IInd Company in line.

Ashen Knights
Similar to the Salamanders Chapter the Omni Legion has a deep respect for their fellow Astartes from the Ashen Knights who value all life. The Chapter may disagree with some of their choices of who they deem worth defending but it doesn't intrude on their missions. Since both Chapters hold such importance of the lives of civilians it isn't uncommon for the Omni Legion to send the IIIrd or IVth Companies to aid the Ashe Knights in the defense and evacuation of civilians if threats such as the Tyranids or Orks are present.

The details of the Ashen Knight's organization is a secret held by the Omni Legion who don't think any such actions should be deemed heretical if used for the benefit of the Imperium of man. After all, what harm is there in having reserves...

Steel Harts
Despite the fanatical nature the Chapter holds for the Codex Astartes it doesn't stop the Omni Legion from operating with them. More specifically the Ist and IVth Companies due to their superior artillery to other Companies. The Omni Legion's history with the Ultramarines has made their relationship with the Steel Harts easy but their tactics and combat doctrines is what truly draws Omni Legionaries to cooperate with them. Despite this the Omni Legion has little tolerance for endangering Guard allies that they feel so compelled to protect.

The trust the Steel Harts show toward the Inquisition puts the Omni Legion on their toes, seeing as how the Chapter has been harassed by the Inquisition for Millennia.

Invictors of Mars
As a fellow Chapter who allies themselves closely with the Adeptus Mechanicus the Omni Legion shares the mission of preserving and salvaging mankind's technology. The older Chapter of the Invictors has undoubtedly inspired the actions of many Omni Legionaries, the care for the people of the Imperium has ensured a good relationship. Despite the overall outlook the Invictors maintain in this regard. Exchanging important Intel and aiding one another during campaigns frequently, often at the request of the Mechanicus of Mars itself.

Rarely would the Omni Legion dare to attack a Hell-Forge but combined with their fore-cousins and the Adeptus Mechanicus itself these forces could lay waste to any traitorous Hereteks and any Titan Legions would dare ally with them. The Legio Sol Devoratores tearing apart their titanic foes while the Astartes take to the planet itself and turn bolter or Melta to any traitors who attempt to fight back, flee or even surrender. Corrupting the Omnissiah's very creations is a punishment made only in death.

Blood of Vulkan
Despite hailing from the Cursed 21st Founding the Omni Legion sees the Astartes of the Blood of Vulkan as reliable allies. Omni Legion has been gifted 20 powerful weapons known as 'Drake Blades' by the Blood of Vulkan while they supplied the Blood of Vulkan with suits of Terminator armour. It is unknown if the Chapters have had similar exchanges of weaponry since the first time they fought together.

Should the Omni Legion require aid against the green-skinned Ork menace they just may call upon the aid of the Blood of Vulkan if their sub-sector is at risk. Typically the combined efforts of the Chapter and Forge World should be enough but one should never turn down a Chapter of Astartes who breath fire when threatened by Orks.

Conflicting Chapters
"They fight for our glorious Omnissiah but they're mindless fools. I'd rather fight alongside a filthy hound of Russ than one of those...those...psychopaths!"

- Captain Vilhelm speaking of the Marines Malevolent

Marines Malevolent
The blatant disregard and hostility these Astartes toward allied Imperial forces and the common citizen disgusts the Omni Legion, viewing this Chapter as enemies of mankind. Refusing to cooperate with them, unlike the Salamanders that simply avoid them the Omni Legion on numerous occasions have threatened to slay them should they enter the Roi Sub-Sector. This is ultimately up to the Adeptus Terra and High Lords of Terra, though the Mechanicus has advised against risking a Chapter vs Chapter conflict. As such the Marines Malevolent are forbidden to enter the Roi Sub-Sector unless commanded to by either the High Lords or Adeptus Terra.

Black Templars
The black armored sons of Dorn have proven to be hesitant allies to the Chapter, their religious ways and prejudice toward psykers. The Omni Legion is still willing to look passed some of the actions and words of the Black Templars, they are honorable and dedicated warriors to the Imperium and are trustworthy as any true Loyalist. Despite this the Omni Legion prefers not to participate in campaigns between just the two of them. Once more, unless it's by order of the High Lords of Terra or the Adeptus Terra.

Only those within the Omni Legion's IInd Company have welcomed the tactics of the Black Templars, while not accepting their religion which is nonsense to them. In recent decades Captain Vilhelm himself has developed an interest in the story of 'The Hero of Helsreach', viewing Merek Grimaldus as inspiration for a leader as apposed to many of those within his own Chapter.

Iron Hands
Despite being suspected successors of the Xth Legiones Astartes the Omni Legion views the Iron Hands as fools that waste technology due to their culture. The strict and brash manner in which the Iron Hands approach combat alongside fellow Imperial forces and the way they treat their scouts by treating even the smallest infraction as a blemish on the Chapter. The Iron Hand's phrase "Flesh is weak" is scoffed upon by the Omni Legion.

Most of the successors of Ferrus Manus' gene-sons are felt the same way by the Omni Legion and will attempt to distance themselves from them. Working rarely with one another, seeing the use of mankind's technology in different ways despite both Chapters sharing very similar cultures and tactics.

Space Wolves
Many within the Chapter view the Wolves to be some of the most barbaric warriors under the Astartes name because of how many times they have gone against the Imperium for their own personal beliefs. The actions of the Space Wolves in the aftermath of the First War for Armageddon are the most notable example in which they initiated a Cold War against the Imperium based on the lives of Imperial soldiers thought to be corrupted by Chaos. The Omni Legion may value the lives of Imperial citizens but they also understand the dangers that Chaos can spread and therefore the mass populace could have been at risk, the lives of the many compared to lives of the few.

The methods in which they confront the maintenance of their technology as well as the ignorance they display when speaking of psykers puts off the Omni Legion who are upholders of knowledge. The culture of the Fenrisian people is no different to those savages who wander the deserts of Tallon Prime, according to the Omni Legion.

Both Chapters have in truth come to blows in the past for the Omni Legion doesn't believe the Space Wolves truly care for the lives of humans but instead that it's an act, that the Wolves are mindless fools that want to be accepted. Perhaps for their Primarch's failings during the events of the Horus Heresy...

Relations to other Imperial Forces
"Terminator Teams! Support the Guardsmen! They shall not fight alone!"

- Recovered Vox recording of Captain Ostrava hours before Cadia fell

Astra Militarum
The brave men and women of the Imperial Guard make up the bulk of the Imperium’s military might and the Omni Legion aren’t ignorant to this fact. Numerous times the Chapter has come to their aid. Despite the history of Space Marines basically stealing the glory of victory and leaving the Guard with nothing but their dead, members of the Omni Legion don’t fall under this and have nothing but respect for the forces of the Astra Militarum for facing such unbelievable odds.

The Omni Legion do what they can to make the Guard feel accomplished and will not stray from any details when speaking of the bravery of any Guardsmen. The young Astartes will be tasked with gaining first hand experience and knowledge of working alongside humans and the importance of their mission to safeguard humanity against the threats that pollute the galaxy.

The strongest bond between the Omni Legion and the Astra Militarum is through the Psian Venatores, the armed defenders of Tallon Prime. These skilled soldiers that fall under the Ordo Tempestus' umbrella make use of the planet's dark environment to train and operate as tactical hunters. Some members of the regiment taming the once thought uncontrollable wildlife of the planet. Commanded not from the cities of Tallon Prime but rather from the planet's moon 'Phaa ' which houses their operations and a small navel base.

Adeptus Mechanicus
Thanks to Roitheta aiding in the recovery and birth of the Omni Legion they believe themselves to be indebted to the Adeptus Mechanicus as a whole. When orders from the AdMech come in the Omni Legion are fast to act and race to complete their missions. Despite these orders from the Mechanicus the Chapter is still given freedom on HOW they accomplish these missions as long as they fulfill their purpose.

Many times the Chapter itself will find their own way to the technologies sought by the Mechanicum. The Mechanicus holds a presence on The Ark at all times and the Forge World of Roitheta supplies the Chapter with their weapons and more. With the increased number of Mechanists that serve on board The Ark one could mistake the entire Chapter as followers of the Machine Cult.

Explorator Zubayr and Magos Domina Mira were both selected personally by Fabricator-General Aliya to monitor and report on the actions and behaviors of the Omni Legion over the millennia. Mira possibly becoming too invested in one Astarte.

Adepta Sororitas
The zealotry behavior of the Sisters of Battle frequently turns the Omni Legion away from wanting to serve with them because of the Sisters willingness to kill anyone who they believe is a heretic.

Even after The Age of Apostasy the only Orders the Omni Legion will agree to working with are the Order of the Argent Shroud and those like them because of their more selfless attitude and outlook on the Imperium. Specifically the Order of the Sacred Flame which works close with the Chapter as their Order was founded and is based on the world Tallon Prime which had been claimed by the Astartes. The Order has been known to accompany the Chapter’s Companies as reinforcements that infiltrate behind enemy lines to take out commanders or a primary source of negotiation because of the more human appearance the Sororitas possess. Many men with power to do as they wish and either join or surrender to the Imperium. Additional information on this Order is disclosed later.

The influence the Omni Legion has bled into the Order and they reshaped into an Order that worships the Omnissiah in name, treating every piece of Imperial technology as holy relics. This zealot attitude still doesn't line up with many within the Chapter though it is preferred to their old ways. The Order of the Sacred Flame call the Omni Legion's former homeworld their new one, entrusting them with the protection of the people.

The Inquisition
The organization that works as the Imperium's secret police they hold as much power as the very High Lords of Terra, even though they suppository answer to the Emperor himself this isn't enough to gain the Omni Legion's favor. Their treatment of the Imperium's people is only the tip of the iceberg to why these Astartes loathe the Inquisition. Many Legionaires of the Chapter needing to force themselves to remain silent should an Inquisitor be around, despite how they feel the power and influence a single Inquisitor possesses is to be feared.

Upon the Chapter's creation several Inquisitors left to the Forge World of Roitheta to see the new Space Marine Chapter, they possessed no records of this Chapter and any and all they could find were closely withheld by the High Lords of Terra. Chapter Master Griffith was confronted by two of these Inquisitors while the other 199 Astartes were still preparing to leave Roitheta in search of a recruitment world. He was questioned for hours and much of what he told them was information given to him by Fabricator-General Aliya in advance, claiming they were in fact created as part of the 7th Founding. Unconvinced of this they reported to Grandmaster "Theodore Holoserica" who agreed that this Chapter's origins were suspicious and would dedicate much of his efforts seeking to expose them.

As millennia passed as did the names of those who sought to bring the Omni Legion's past to light, the loyalty the Chapter displayed and even an Order of the Adeptus Sororitas allying with them made it increasingly difficult. Many successors would replace those Inquisitors who obsessed over the Chapter. Calling for as much information about the Chapter as possible. Gene-Seed records, Chapter strength and even detailed reports of all their campaigns covered by both the Astartes and the Adeptus Mechanicus or any other allied forces that may have been present. Despite all this they seem intent on proving something. After thousands of years maybe it's just tradition and it's too difficult to let it go.

Rogue Traders
These intergalactic merchants and travelers are no strangers to the Omni Legion who seeks them out for their valuable finds, sometimes sending their own Astartes to accompany the Traders should the Chapter call upon their aid in finding mankind's lost technologies. The Chapter pays Traders the typical rewards one would expect but with the additions of weapons and munitions. Should the Chapter discover that a group of Rogue Traders are hiding something as valuable as an STC they wouldn't hesitate to slaughter them.

When meeting with the Omni Legion to partake in their dealings the Traders will be directed to the Chapter's Fortress-Monastery, The Ark. Their ships will be resupplied and their crews welcomed and given a warm welcome as allies to the Chapter, meals provided by the Chapter's Companions. Rogue Traders that wish to deal with the Omni Legion must first be given the proper credentials to ensure they can travel safely throughout the Roi Sub-sector, or risk being attacked by the Chapter's IInd Company.

Abhumans
The Omni Legion cares very little about the differences between humans and Abhumans, as such they treat them as the same. Humans evolving and adapting to their own environments fascinates the Chapter's very own Apothecarion and researching the pros and cons of each Abhuman strain. The only strains that they show a level of caution toward are Ratlings or Mutants, in many cases they'll outright refuse them access in boarding their ships. The Squats are well liked by the Omni Legion because of their shared love for technology and exchange such resources.

Relations to Xenos races
"Order all forces fall back...the world is lost. We must destroy this threat no matter what!...order Exterminatus."

- Attributed to an unknown Omni Legion Commander

=== The Tau Empire === The Tau aren’t a faction they will engage in combat on sight. However if they don’t heed their warnings to stay back they’ll attempt to wipe the Tau out, if they retreat they won’t pursue. Despite the proximity the Omni Legion’s investigations and patrols place them to the Tau empire they have rarely encountered them. Such events only occurring in the last millennia.

If the Chapter can identify a soldier of the Tau Empire as a human they will wipe out all Tau resistance and forcefully take the human deserter to subject them to questioning, beyond that the Omni Legion don’t care what happens to the traitor. The DNA bound weapons of the Tau only have any value to The Chapter if they're from a human, another reason they are so eager to capture these humans.

The Farsight Enclave may prove to be a faction of the Tau who the Omni Legion would be willing to form alliances with. This is due to Commander Farsight himself being an esteemed warrior and leader rather than a typical political figure who'd never hold a weapon. In fact there are those who suspect that the Chapter has attempted to gain Tau weaponry from the Farsight Enclave for the sake of personal curiosity and the Mechanicus.

The Eldar
The Omni Legion never seek conflicts with other Xenos races such as the Eldar because they believe that neither faction would benefit from it. The sight of an Eldar Craftworld will make the Astartes wary to them but only keeping an eye on them should they get too close to their fleets or the world they’re investigating.

The only Eldar faction they ally themselves directly with is the Ynnari, very similar to many within the Imperium this is due to the aid in the resurrection of the Ultramarines Primarch Roboute Guilliman. The IInd Company despite their anti-xenos outlook will work alongside these Eldar for this reason.

The Dark Eldar
The Omni Legion has rarely encountered the Drukhari as they attempted to raid nearby systems which managed to get out a distress signal before communications are lost. These few instances resulted in minimal loss to the Chapter but a major loss of Imperium citizens being captured and taken away by the Drukhari into the webway. Numerous attempts have been made to pursue the Xenos as they flee to Commorragh but it has always resulted in failure.

More common sightings of these Xenos in recent Millennia have been of the "Kabal of the broken sigil" as they have launched a massive offensive against the Necron "Sautekh Dynasty" in the Eastern Fringe. A conflicting scenario as both races have proven to be a danger to the Imperium of man. Investigation missions have been launched to survey the conflict for the last 100 years.

The Necrons
The mission of The Omni Legion means that the risk of encountering Necrons is much higher than most other Astartes. They have come to blows with these mechanical foes countless times. The first attempt to converse with these beings resulted with a conflict that lasted 50 days and 49 nights before the Astartes withdrew from the planet.

Necron technology is banned from being brought aboard any land or aerial transports let alone The Ark because the Chapter doesn’t want to risk the chances of Necrons being able to taint their Fortress Monastery.

The most prominent figure of the Necrons that gets the attention of the Chapter is the Necron Overlord Trazyn. Upon learning of a Necron Overlord who holds such a large collection of relics there have been countless attempts to capture or find him, Trazyn himself has attempted to do the same with members of the Chapter.

The Orks
Due to the location of the Forge World of Roitheta they encounter attacks from the Ork Empire of Charadon on many occasions. Typically ending with the Ork fleet being wiped clean from the stars. The green skinned Xenos frequently comes to blows with the world's Titan Legion and the Omni Legion's IIndCompany.

Since the Chapter frequently moves between Roitheta and their next target for investigation the Orks have tried to learn their patterns and attempted to catch them off guard. Most times it's after The Omni Legion leave Roitheta. The Orks will attempt to use overwhelming numbers to fight the Chapter to no avail.

There are those in the Ordo Xenos who suspect that the Chapter has made contact with Ork Freebooters, specifically Renegade Mekboyz. Like many claims against the Chapter these claims have not been proven to be correct, once more actions made by the Inquisition halted by interference from both the High Lords of Terra and the Adeptus Mechanicus. Surprisingly there is one Conclave of the Inquisition who claims that such actions of the Chapter are false, the same who has watched over them since their inception.

The Tyranids
Negotiations are not an option. Kill them on sight. If a planet is suspected to hold either of these species the Omni Legion will deploy the Ist, IInd, IIIrd and IVth Companies to destroy every Xeno they can find. This is however very rare as the duty of the Chapter isn't to hunt Xenos. If orders are however to deal with such a threat in the event another Space Marine Chapter, the Ordo Xenos or Imperial Guard are unable to reach the world before them then they’ll do what needs to be done.

Obviously this also includes all forms of Genestealer cults and the worlds they inhabit. It brings great grief to the Astartes should they need to wipe out an entire planet's populace but in order to protect mankind and preserve the galaxy it must be done.

Captain Ostrava
One of the most fondly remembered Captains of the Omni Legion's history, Ostrava was the Captain of the Ist Company till the dawn of the 42nd Millennium. He wielded one of the Chapter's greatest relics, the Drake Sword named ''Helm Breaker. ''Ostrava was what many thought was a the perfect example of a what it meant to be a member of this Space Marine Chapter.

It's believed that he ultimately died during the Fall of Cadia. Leading an assault against the charging forces of Chaos he and most of his Honour Guards led the Chapter's Veterans to battle where they'd fight till the end. The fate of Ostrava is unknown, some in the Chapter believe he's still alive, somehow surviving the destruction of Cadia while he was still standing upon its surface. The survivors of the Company would eventually retreat from the system led by Lieutenant Fenix by order of Ostrava.

Lieutenant Fenix
Fenix is the current 1st Lieutenant of the Ist Company, one of the few surviving leaders of the Company after the destruction of Cadia. After the events of the 13th Black Crusade Fenix with the remains of the Chapter's Ist Company would be lost after making an attempted warp jump to flee the system while pursued by ships belonging to the Black Legion, their whereabouts unknown for over a century. They would only reappear in the latter years of the Indomitus Crusade to provide aid to the Imperial world of Harmyn which had fallen into Chaos. Dominated by the Lost and the Damned led by Heretic Astartes. Only the island continent of Vinasili remained unbroken, protected by both remnants of the world's PDFs and surviving Astartes from the Ignis Condors Chapter. Fenix and his brothers would help defend the capital city in their final years before aid from the Omni Legion would appear in the form of the entire Chapter.

Upon Fenix's return to the Chapter he would be one of the few to take on the Rubicon Primaris successfully, now stronger than before Fenix is seen as the unofficial leader of the Ist Company by his non-Primaris brothers.

Captain Vasilis
The current Captain of the Ist Company, a Primaris Marine who had been trained over the course of ten thousand years to play the role of a commander. He was placed in command of the Omni Legion's new Ist Company by order of Roboute Guilliman only a decade into the Indomitus Crusade. Taken from the ranks of the Unnumbered Sons Vasilis was chosen because of his exceptional record both during his time training on Mars and leading a contingent of his Primaris brothers against the Death Guard Traitor Legion.

Vasilis' weapon of choice is a relic given to him by Chapter Master Artorias after his arrival, it is in truth a relic taken from the renegade Chapter the 'Pale Fangs'. This weapon is a sword similar to Ostrava's but this one was partnered with a shield as its sheath, the shield provides a steady charge for the blade while it's sheathed inside. It's name is ' Fenris' Fang '. Fenris' Fang is equipped with a powerful kinetic field that can knock back enemies that strike the shield with a physical impact. Vasilis makes use of the newly implemented Mark X: Gravis armour, in the span of over a century it has already diverged from its original design. The shield he wields is capable of mag-locking to his right forearm, leaving his hands free to grasp anything.

Captain Vilhelm
The most violent and aggressive of all the Captains he has zero tolerance for nearly any Xenos race, the only reason he won't fire upon the Eldar in recent years is because of their involvement with resurrecting Roboute Guilliman. Many would assume from Vilhelm's personality that he'd risk going mad with rage and become something akin to the Khorne Berserkers, though the only thing that Vilhelm hates more than Xenos is traitors to the Imperium.

Vilhelm will often take to the field of battle in his custom Cataphractii Terminator armour while accompanied by his Honour Guards, which are refereed to as 'Executioners'. His weapons of choice alternate between his battlefield. His most notable are his relic Claws bound to his Cataphractii suit, ' Hell ' and ' Heaven '. Both claws with built in bolters seen along the knuckles allowing for close ranged firefights.

Captain Logan
Easily described as the most charismatic Captain in the Chapter, he's also the youngest in the Chapter's history to reach this rank. Logan works personally with his forces when the need for mass evacuations and reinforcing Guard Regiments is there. Standing alongside Generals on the battlefield, turning down offers from Lord Generals to view the battles from a distance.

His crimson jewel embedded is a sign of good fortune he eventually had embedded into his power armour when promoted to Captain of the IIIrd Company. His carefree nature was brought to the forefront as Logan had a nickname given to him by his brothers, ' Immortal Logan' due to the crazy stunts he'd manage to pull off. One of which was the act of destroying an Ork Gargant alone, jumping out of its mouth as the entire thing exploded.

Clad in heavily modified Mark III power armour with a bright red gem embedded in the center of the chest and wielding a power fist and Combi-Plasma pistol. His place has always been standing with his allies and running through the battlefield with the aid of his Jump-pack in a calm manner avoiding enemy fire with ease and providing cover to their allies.

Captain Tristan
The clad in cold steel Captain of the IVth Company has lived for millennia as a powerful Contemptor Dreadnought. Supported by the Company's additional Mechanists and even the aid of Enginseers he has led them for nearly 5000 years.

Early in his career as Captain he would stand in the front lines with his men, refusing to put them into dangers he himself wouldn't put himself through. His weapon of choice was a great Thunder-hammer called ' The Omnissiah's Fist', it could shatter a traitor's power armour with a single swing. Assisted in battle with his Honour Guards who unlike most others were equipped with additional ranged weaponry, very similar to Tristan they possessed shoulder and wrist mounted stormbolters.

As the millennia passed Captain Tristan became a cold and calculated leader that operated on the front line, as a living war machine and wall to protect his brothers. Ordering his commanders to lead their forces in the thick of battle Tristan rarely takes command himself. Becoming very close to the Magos Domina Mira. She tends to him every moment she gets, viewing him as a prized possession and a great piece of work that she has maintained for longer than any other device she has held. Though she seems jealous as Tristan sometimes speaks of his angel, a woman who saved him from death.

Captain Gael
The strict and seasoned Captain of the Vth Company is the oldest living Astarte in the Chapter. A master of stealth and performing hard hitting ambushes against enemy forces. It's believed Gael could very well have left his role to become the Captain of the Ist Company centuries ago, perhaps even becoming Chapter Master due to his skills. Though he doesn't believe anyone is yet capable of training the Chapter's Initiates as well as he and changing such would only hurt the Chapter. He was once a member of the Deathwatch during his service in the Ist Company and wished to return to the Vth Company rather than joining the Praetor Dominus.

Thanks to the Rubicon Primaris Gael makes extensive use of the Mark X Phobos Armour. A dark hood attached to an equally dark cloak will typically cover his helmet. His personal weapons are a pair of heavy bolt pistols that go by the names ' Mercy ' and ' Redemption '. Both are scarred and damaged over a millennia of use but function as if they were new, capable of blowing a hole through a suit of power armour with ease. Though he uses them sparingly since they're obviously not the quietest weapons he uses. His final weapon is ' Strife ', a modified Sniper Rifle that makes use of the unique ammo types one would find in the service of the Deathwatch.

Apothecary Dominus Vinland
The leader of the Apothecarion he has been tasked with monitoring the Chapter's Gene-Seed and pursuing the education of the Chapter's Apothecaries, he has seen the recovery of many Battle Brothers and the implantation of many Gene-Seeds along with the Magos Biologis. Keeping a service of Apothecaries with him at all times they may see some of the bloodiest battles the Chapter is tasked with. Despite his vital role he ensures what he has learned has been passed to his students as quickly as possible, whenever he is away he always leaves one such student behind should anything happen to him.

Vinland suffered a psychic attack from a Tzeentch Daemon Sorcerer years ago and it resulted in his mind being split into two different personalities. One where he retains the calm demeanor he was known for and another that develops when in the presence of Chaos in which he becomes a blood thirsty killer seeking for the death of all heretics. Thankfully such an affliction doesn't cause any significant hindrances to Vinland's work. Though with the appearance of the Great Rift Vinland's mind is thought to be slowly degrading, only becoming more noticeable by 107.M42, his more violent personality bleeding through even in the presence of just his brothers. The Rubicon Primaris is one solution Vinland has considered but concern of it failing to avail results has kept him silent about pursuing such a path.

Warden Dominus Boldwin
Master of the Chapter's Armoury Boldwin only follows orders from the Chapter Master or the Adeptus Mechanicus of Roitheta, granted ancient and powerful weapons that make him death incarnate should he ever take to the field of battle. Many years he'll spend upon The Ark maintaining vehicles and weapons, ensuring the machine spirits are tended to should the Chapter's Mechanists be insufficient. Boldwin's brothers match those with any other Chapter in their knowledge but they pride themselves in their faith in the Machine God, lending their teachings to their battle Brothers as a result.

Should one of the Chapter's Companies uncover an STC he'd be made aware of it as soon as possible, wishing to be the one to personally hand it over to Fabricator-General Aliya. His armour is black as a result of hiding away deep in the Chapter's workshops, any battle scars across his armour would display as blood red from the original scheme that has been crusted over by smoke and torch marks. Both his appearance and machine-like personality have earned him the nickname 'The Scarred Golem'.

Librarian Dominus Gwynn
Gwynn is one of the few within the Chapter who was quick to embrace the Ynnari as possible allies should the moment call for it, the Chapter may have not been violent towards the Eldar but they were still wary. Viewing the race's Psykers as a step in humanities' evolution that all should look forward to, even if those such as the Black Templars or Adeptus Sororitas share a burning hatred for the "witch".

Gwynn encourages his understudies to utilize their Psychic powers to their fullest extent to truly lay waste to their foes. On the field of battle Gwynn will cast great bolts of psychic lightning that will burn the flesh and peal the armour from any foes that stand in his way, he is a master of Technomancy.

The Librarian Dominus still prefers to confine himself to his studies, assisting the Chapter Master by communicating with his students that serve each Company. Ensuring that not one single Company is disconnected from the Chapter's command.

Praetor Dominus Nero
Very little information is available about this individual. Nero's role doesn't place him as a typical Praetor Dominus, instead Nero will be assigned tasks by the Chapter Master or Fabricator-General. Fulfilling objectives very similar to the Explorators of the Adeptus Mechanicus. Assigned his own force to accompany him onto his mission. In order to complete his task Nero is granted not command but permission to utilize one of the Forge World's Ark Mechanicus ships during his quest for knowledge.

Chapter Master Griffith
The original Chapter Master of the Omni Legion, hand picked from the 200 Astartes recovered by the Explorator fleet led by Zubayr and given their name and titles by Fabricator-General Aliya. It's unknown why he was chosen to lead his brothers, some think it was random but others think it was a character trait that the Fabricator-General could see that others couldn't. His first assignment was to seek out a recruitment world which he accomplished by seeking a world outside their own sub-sector as there were no worlds in the Roi sub-sector that would be efficient in this task.

Griffith would vanish sometime in early M35 during a campaign to flush out Ork war bands who had entered the Beta system in the Roi Sub-Sector. Upon the world of 'Mazul' Chapter Master Griffith would lead an attack upon the world, he and the Ist Company with their Captain would strike the heart of the enemy while the other Companies fought off the surrounding forces. During the battle the Ork war boss fought Griffith, the pair during their duel falling deep into the planet's depths, the ground shattering below their feet. After the battle was won the Chapter searched for weeks to recover their Chapter Master but he was never found. It is odd that before departing to battle he equipped himself with a suit of the Chapter's standard power armour, ensuring that his original suit would be passed down to his successor.

Chapter Master Artorias
Artorias has been the Chapter Master of the Omni Legion for 165 years, previously he was the Captain of the IIIrd Company. The cause of his promotion was a result of-

[REDACTED]

Even as far back during his time in the Vth Company Artorias was dedicated to his role defending the people of the Imperium, losing an eye protecting a squad of Guardsmen. Strategies that prioritize low casualties while maximizing enemy fatalities require a tactical genius winch Artorias has proven to be. Always craving both battle and knowledge Artorias despite his role will take to the battlefield without hesitating for he learned from the great captain Tristan that no commander order their men to do what they themselves would not.

The Indomitus Crusade would be the true test of Artorias' leadership of the Chapter, leading each active Captain and their Companies to battle against the forces of Chaos.

Royce Mensis
The Chapter's current Reclusiarch. Royce spent most of his career in the IVth Company as one of the most venerated Mechanists so it was no surprise when he was promoted to Warden. Royce has gained the attention of Captain Tristan who seeks to make him his successor. Despite the Chapter strictly forbidding those who walk the path of the Machine Cult from having command of an entire Company or beyond.

Royce was sent by Tristan to the Deathwatch not long after he achieved the position of Warden, his service there would not last though. In less than fifty years Cadia would be destroyed and the Chapter's Astartes would all be recalled as a result. Royce would rejoin the IVth Company while the Omni Legion despite the loss of the Ist Company aided Imperial forces against the forces of Chaos. The influx of brothers provided by the Primaris Marines would lead to many First Generation Astartes in the Omni Legion becoming promoted thanks to their efforts in fighting back against the dark. Royce would be chosen to become Reclusiarch by Chapter Master Artorias following the death of Reclusiarch Vamos. Another step Royce took was to part-take in the Rubicon Primaris, becoming faster and stronger than he was before.

Chapter Relics
''Most relics within the Chapter are unknown, this is due to many are taken upon the destruction of a renegade Chapter. The following listed will be those who are in active use by the Chapter.''

Cerberus' Fang: a sturdy shield capable of acting a sheath that charges the powerful blade with the energy is uses to cut through thick armour plating with ease. The last owner of this weapon before coming into possession of the Omni Legion was Chapter Master Ulfric Stormhowl, before he and his Chapter were slain. It is currently in the care of Captain Vasilis of the Chapter's Ist Company.

Helm Breaker: One of the Chapter's 20 relics known as 'Drake Blades' gifted to them by the Blood of Vulkan, currently in the hands of Lieutenant Fenix. Gifted to Fenix by Captain Ostrava in the final hours of Cadia's defense before the Captain sought out Abaddon the Despoiler, never daring to retreat but unwilling to risk losing an ancient weapon gifted to the Chapter.

Heaven and Hell: A pair of Lightning claws that were discovered by the IVth Company and Captain Tristan in mid-M38. Taken from the possession of a Renegade Warband's leader, thankfully the Astartes hadn't fallen to the temptations of Chaos and the weapons were salvageable. The weapons would spend the next 100 years being purified by the Chapter's Mechanists and the Tech Priests of Roitheta. Eventually deemed purified and their machine spirits saved. Vilhelm would choose these as his weapons of choice upon being promoted to Captain.

Mercy and Redemption: Powerful bolt pistols that closely resemble the newly developed model utilized by Primaris Reivers. The powerful shots they produce can pierce most types of armour, even some patterns of Terminator armour can be shot down by these weapons. Taken from the vault by Captain Gael once he was given the rank of Captain, the true origins of these pistols were lost. Most of the vault's records were lost after the loss of the Chapter's original Fortress-Monastery. Mercy is described as a clean white and a silver finish while Redemption is black with a beautiful golden trim.

Strife: Another relic wielded by the Vth Company's Captain, a sniper rifle that has seen countless millennia pass by, rumors speak of it's true origin being that of the Officio Assassinorum's Vindicare Temple, a powerful and ancient Exitus Rifle. How such a weapon came into the Chapter's possession is unknown. Strife has been modified by the Chapter's Mechanists and their Tech Priest allies.

[CHAPTER RECORD REDACTED]
''Local files held by the Chapter are missing, such records are still held by other departments of the Adeptus Administratum. These records make mention of a campaign in which the Chapter was ordered to exterminate a planet's hostile human populace in order to recover a possible STC unit. It's suspected the Chapter wishes to forget such an event.''

Chapter Colours
The armour of the Omni Legion primarily have a silver colour scheme with a red trim along the pauldrons, knees and the plating covering the stabilizing jets of their backpacks. Every Astarte has blue eyes on their helmets. Sergeants may wear older models of helmets to help them stand out better among their brothers and display the Astarte's legacy. Captains aren't held to a specific code and are free to appear as they please as long as they display the Chapter's emblem and their Company's number.

The origins of their colour scheme comes from a choice made by the Chapter's first Chapter Master. Griffith decided that the same red as the Mechanicus would be satisfactory for the Chapter did not need anything extravagant.

Chapter Badge
The Omni Legion's Chapter badge is a white coloured Cog Mechanicum icon - the ancient symbol used to represent the Adeptus Mechanicus and their religious faith, the Cult Mechanicus. This emblem takes the form of a halved human/cyborg skull, which represents the fusion of flesh with the holy machine. This icon is centered upon a white circlet centered on a field of red and surrounded on the left side by a half-cog symbol, which represents the Chapter's close ties with the Adeptus Mechanicus.
