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

The Omni Legion is a fleet-based Chapter with close ties to the Adeptus Mechanicus while cooperating frequently with the Adepta Sororitas Order of the Sacred Flame. They pride themselves as sentinels of both the Imperium and its history as they seek out technologies thought lost and protect what mankind already has.

Despite their undying loyalty to the Imperium the Chapter's history has made the Inquisition suspicious of their very existence. 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.

Founding
Early in M34 a Space Marine Chapter would appear to assist both the Salamanders and Terra's Cockroaches Chapters during a campaign known as the Cleansing of Patron. The Omni Legion during their first appearance only fought as a Chapter of two hundred. Over the next year the three Chapters and Imperial Regiment fought against an invading Ork WAAAGH! By the conclusion of the campaign over half of the Omni Legion's forces were wiped out. News of their existence would quickly make it back to the High Lords of Terra who had no knowledge of this Chapter existing, the Forge World of Roitheta would be contacted by the High Lords as a result.

Fabricator-General Aliya would speak with the High Lords themselves, explaining that the Omni Legion was crafted by the Forge World by her orders. Claiming that they had every intention of alerting the High Lords to this development after the Chapter's reports and assessments following the campaign. Several years would go by until eventually the 7th Founding would come to pass which saw the Omni Legion's name appearing within it's few records.

It was determined that the Forge World of Roithea would serve as the Chapter’s supplier for weapons and vehicles. Production for the world boomed as they received additional resources from nearby systems to aid in production ranging from a bolt pistol to cruisers. The High Lords of Terra made the decision to have this new Chapter operate in the Segmentum Ultima while remaining under strict regulations and more than often tithes of their Gene-Seed due to their unusual mutations.

With a single Dauntless-class Light Cruiser this new Chapter of less than one hundred Astartes took to the stars to find a recruitment world. The Omni Legion would seemingly vanish from the greater galaxy for several centuries as they established themselves proper.

Claiming Tallon Prime
In the year 487.M34 the Desert World of Tallon Prime was contacted by the Omni Legion. Their first Chapter Master Griffith would lead a small party to the planet's surface, to one of the Hive Cities while accompanied by members of the Adeptus Mechanicus. Viceroy Irmfried of Hive City Vigil would be the first human to meet with them alongside his retinue of scribes, officers and priests. The latter greeting the Astartes with thuribles filled with incense, swaying side-to-side allowing the smoke to loft around them. Officers saluting the Marines who were admittedly surprised by the greeting, Griffith was welcomed to accompany the Viceroy to his home to properly introduce himself, obviously never having met one of the Adeptus Astartes himself.

While the Chapter Master was preoccupied with discussing future plans of Tallon Prime with members of the Mechanicus additional shuttles would be sent to other Hive Cities, all carrying Astartes and Tech Priests. Each revenue had one representative for the Astartes accompany the Tech Priests while the others were free to explore the Upper sections of the respective Hives. The most prestigious of Tallon Prime were shocked to see these armored warriors of the Emperor patrolling the streets, taking in the sights and even inspecting training PDF forces as to examine their training regimens, even if they were distracted by the Astartes watching them. Days later the Astartes would all return to their Strike Cruiser which had remained in orbit, many now crowding to see their shuttles leaving from the highest points of the Hive City, only few able to see even from the highest points of the Hives. Hours later the individual Hive City Viceroys would all announce to their citizens the news of their world now under the protection of the Emperor's Angels of death, many hailed this news as fantastic, nights filled with celebration from nobles hosting grand parties, the Lower Cities having their own festivities while the Slums detested this news.

Return of the Omni Legion
796.M34 reports of a possible Ork fleet appearing in the Tallon system sent all of Tallon Prime's PDFs into a frenzy, orbital stations on high alert for the coming days. All the while a small fleet appeared not far from the world, ID codes identified the group of Cruisers as those under the command of the Omni Legion. Already much larger than it had been nearly three centuries ago the Chapter also possessed a new Battle Barge fresh from the shipyards of Roitheta and ready to destroy their foes. The following days would keep tensions high until the expected Xenos finally appeared....though the size was not nearly as large as reports had earlier indicated.

Despite the seeming lesser threat the Astartes engaged the Orks long before they could reach Tallon Prime nor either of it's moons. Instead the Astartes fleet would engage the clustered Ork fleet, kitting them toward a dead world within the system. Clever hit and run tactics would lead to several Ork vessels colliding with one another or firing upon their allies which only lead to further in-fighting. The situation made it easy to force the Xenos to the planet, many of their burning ships falling to the planet surface.

The following hours would consist of hundreds of Astartes dropping to the planet surface to engage the bewildered Orks who had no chance of surviving, the nearly oxygen deprived atmosphere on the planet made it easy for the Astartes to overwhelm the Orks. Battle tanks deployed to the surface to lay waste to the few ramshackled Ork vehicles that somehow survived the crash while ships from orbit bombarded the remains of their vessels. It would not be long before the green-skins were slaughtered, returning to their ships in orbit the Omni Legion along with Tallon Prime's support vessels bombarded the planet to ensure that even if a single spore remained in the airless void of space that it could never drift through the endless expanses of space.

Spare not the Xeno
Not long after the destruction of the green-skins the Omni Legion's Battle Barge became well known among the planet's PDFs, viewing the grand ship with awe.

Tallon Prime
The planet is roughly 5540 km in its radii, putting it roughly 15% smaller than Holy Terra. The purpose was to find a world that would best suit training the Chapter’s Initiates and Tallon Prime was found, the Hive cities supplying a steady stream of Aspirants with their massive population.

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 the accompanying Magos Dominus and the Chapter's Lord Warden before it’s taken to Roitheta to ensure it’s condition and any additional research performed before it’s turned over.

Deep inside this massive space fortress would appear to be an endless maze to those who have never traversed it's halls before, it takes many years of service before one becomes familiar with most of these paths. 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 Techmarines, Wardens (Chaplains) and Tech-Priests of the Mechanicus.

Should the entire Chapter be dispatched to multiple campaigns they will leave the ship to their Serfs and 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 command 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 Battle Companies of the Omni Legion who're known to excel at void warfare have from time to time called upon the aid of The Ark.

Chapter Organisation
This Chapter is divergent from the Codex Astartes, possessing Six Companies. Chapter Master Griffith determined that it would be too risky to split their forces too thinly as the Chapter struggled to maintain a sizable military force. Attempting to follow the basic ideals of the Codex Astartes it was decided that there would be one Veteran Company, two Battle companies, two Reserve Companies and a Scout Company (dubbed the Initiate Company).

Since the implantation of the Primaris Marines both Battle Companies and Reserve Companies maintain an equal two hundred Battle Brothers each while the Initiate Company was reinforced by the Vanguard Primaris. The decision to maintain the Six Company organization is due to the Chapter's long standing tradition of a Six Company system and the desire to bolster their Companies into a mightier force.

The Chapter's Battle Companies been known to track down Renegade Chapters in order to salvage what technology they can from the traitors. Should the technology of these Renegades remain untouched by the taint of Chaos it is taken by the Omni Legion to be turned over to the Adeptus Mechanicus. Most of their finds make their way back to loyalist Chapters or other branches of the Adeptus Terra but sometimes their work is rewarded.

Due to the Chapter's genetic defects the average number of battle brothers in the Chapter at most would reach around seven hundred while they still attempted to keep up with their Gene-Seed tithes. Millennia would pass until the return of Roboute Guilliman and the Ultima Founding, the awakening of the Primaris Marines would also see to it that the Chapter's ranks increased to the traditional one thousand, the Omni Legion becoming mightier than it had ever before.

Ranks of the Chapter

 * Aspirant - The young boys abducted by the Mechanicus with the intent of transforming them into Astartes of the Chapter. Others come from the populace of Tallon Prime who are willing to give up their child for a chance to become an Astarte. Only after completing the trials required of them the boys will be subjected to psycho-indoctrination and afterward they will be given a new name.


 * 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 IVth or Vth Companies for one final mission, complete one campaign alongside their battle brothers and gain as much experience as they can while they serve on the front lines.


 * Battle Brother - Astartes who complete their training in the VIthCompany will finally achieve this rank, proven to be warrior of the Emperor. Once their service to the Vthand IVth Companies in their respective Devastator and Assault squads is complete the Astarte will return to The Ark to have the Progenoid Gland in their neck removed to signify their graduation.


 * Sergeant - Squad leaders of these Astartes are granted this title because of their iron resolve and unbreakable bond with their battle brothers. Guiding his brothers through the forests, deserts, tundras and hell landscapes to exterminate the enemies of mankind. Once a battle Brother reaches this rank they are gifted a piece of armour from the Ark's vault, these pieces taken from the remains of heroes laid to rest.


 * 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 as to ensure that their strategies are seemingly as perfect as can be.


 * 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, a master of hundreds of battle brothers that will never turn down the chance to lead from the battlefield. A tactical genius who may command 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. The ruling of Tallon Prime may fall upon the Chapter Master as well, sorting through the regulations and proposals of each Hive's Viceroy to either clear them or deny them. In some cases the Chapter Master may force a Hive City's Viceroy to step down to be replaced by someone he deems more fitting.

Specialist Ranks

 * 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.


 * Lord Librarian (Chief 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 abilities. The research performed through their leadership has stockpiled for many millennia. The Chapter's method of training their Psykers is by the Lord Librarian forcing the Chroniclers to endure powerful and terrifying visions to test their mental fortitude, even pushing them to test their psychic might against the Lord Librarian himself.


 * Techmarines - 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 Techmarines 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 Techmarines, similar to Iron Fathers of the Iron Hands they are a combination of Techmarine with the skull faced Chaplain. Leading a squad of Techmarines into battle alongside the rest of the Company's command as they stand knee-deep in blood while rallying his brothers to war. Each Warden is skilled in the art of forging weapons and armour, so many of those found in the Chapter's armory are forged by them. Even the Chapter's Master Crafted Weapons are created by the Wardens.


 * 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 accompany the Lord Scion in his endless quest for recovering lost technologies to expand their collection. He is the only one with the knowledge of every item within the Vault itself, able to wander it's winding halls with ease without the worry of any Skitarii getting in his way.


 * Lord Warden (Master of the Forge/Master of Sanctity) - Working alongside the Magos Dominus 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 alongside his own personal chosen Techmarines, only leaving the great Fortress-Monastery in service to the Machine God by aiding the Chapter Master.


 * 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 assist 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 Techmarines, 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.


 * Lord Apothecary - 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.


 * Ancient 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 Chapter's Ancient will stand alongside the Chapter Master following him as his shadow.


 * Veteran Marines- Expert soldiers from 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 utilize the legendary Terminator armour and equipped with some of the deadliest weapons the Imperium has to offer. - Sometimes those who would surrender their treasures to the Veterans have the chance of being spared for a time. Broken into teams of Sternguards or Vanguards depending on the mission and roles necessary to achieve victory. Company Veterans are chosen from the Ist Company to aid and defend the Company Captain on the battlefield.


 * Honour Guards- Proven to be invaluable warriors that are equipped with powerful blades and durable shields. Honour Guard are equipped for fast movement, high defense and deadly close range capabilities. Those from the Chapter's elite Ist Company are the only worthy enough to be tasked with guarding the Chapter Master, an additional requirement is that they must have served as a Company Champion at least once.


 * Company Champions - The greatest swordsmen among the Chapter's Honour Guard. Captains of the Omni Legion often wish to lead a battle fighting alongside their soldiers, though should the moment arise they will stand back as simply a commander the Champion shall take to the field and lead their brothers in the Captains stead.
 * Chapter Champion -


 * Scions - The few who survive their service to the Deathwatch serve the Lord Scion and the Mechanicus, all take an oath of silence on everything they see and do. Equipped relic weapons and armour hidden within the Chapter Vault. Visually they're distinct from the rest of the Chapter with most of their prominent silver replaced with red, their names and history will then be scrubbed from all records. Those within the Scions of the Omnissiah are expected to die, there is no place for personal glory here.


 * The Lord Scion - 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. His role is to lead the Chapter's Scions across the Galaxy seeking technologies lost and new to ensure the Mechanicus can lead mankind's technological advancement in the absence of the Emperor.

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 Techmarines.

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 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 Emperor himself envisioned for the Imperium.

IInd and IIIrd Company
Both Battle Companies are the most skilled in void based combat and boarding operations. Many fleets have disappeared because of their work. Boarding teams making extensive use of Reivers who are fast to board and take a ship's bridge while their defenses attempt to fight off Battleline teams. The capture of enemy vessels is prioritized above all else for technology is sacred and must be salvaged and recovered.

Once reaching the planet surface the vast tactics utilized by the Company reflects the time each and every brother spent honing their skills in their service of the Chapter's Reserve Companies. Close Support Squads cut blades into their prey, Fire Support Squads blow apart their targets from a distance while Battleline Squads, the backbone of any Chapter, can do all this and more. Some of the greatest of the Chapter's weapons and vehicles are gifted to the Battle Companies for they see the most combat out of any other Company in the Chapter.

IVth Company
The IV th  Company specializes in close quarters combat, Battleline squads create gun lines that mow down advancing foes. Close Support squads swarm the enemy, cutting them down viciously. Light attack vehicles performing hit-and-run attacks in the chaos of war.

Borrowed Initiate squads assist in the evacuation of civilians as a means to keep them clear of the Astartes in case the defense line is broken, working to get everyone either off world or in shelters before joining the fight alongside their brothers or soldiers of the Astra Militarum.

Vth Company
Repulsors and Land Raiders cross the ravaged war zones that the Company is known for creating with their excessive firepower. Fire Support squads blow apart any advancing or retreating forces whilst Battleline squads with deadly accuracy and devastating results. It's believed that the Vth Company who can hold a strategic location for months should the moment arise.

Due to the mass of heavy weapons and vehicles the Vth Company utilizes the mortality rates of this Company are higher than any other in the Chapter, most of the Company's Command forces are required to done Terminator pattern armour for their safety.

VIth Company
The VIth Company operates in Semi-Companies, each led by the Company Lieutenant with a fellow Apothecary assigned to the Semi-Company. Each Lieutenant is trusted the command of the Semi-Company and will be granted command of their own Vanguard Class Light Cruiser. As with most Chapters, Sergeants leading squads of Initiates are volunteers chosen from the Chapter's elite Ist Company, ensuring that their knowledge is passed down to the next generation of Astartes.

These Semi-Companies since the earliest days of the Chapter's history have been utilized to infiltrate system defenses and report on enemy habitations and military installations. This information has always been crucial to the Chapter to prepare their remaining Companies for war, allowing the Chapter's battle brothers to attack vital targets without charging into unknown territory.

In recent years the Company's Captain begun leading a force of Vanguard Primaris across the Segmentum to either aid the Chapter itself or the Astra Militarum. Infiltrators and Eliminators have proven to be dangerous and valuable soldiers that can turn the tide of an entire campaign with their tactics.

Scions of the Omnissiah
This group's actions are mostly unknown to even the Chapter's Captains, most battle brothers will never see the Lord Scion let alone a member of this Brotherhood. The crimson armour of any Scion is the sign that they have been recognized by the Omnissiah through their actions and the honour they bring to the Chapter.

The Ordo Xenos has crossed paths with the Sons of the Omnissiah as both groups seek knowledge and technology of Xenos origin. Inquisitors of the Ordo Machinum will have their chance to command the Scion of the Omnissiah as they scour the Galaxy for technologies once thought lost to the Imperium. Their expeditions are ordinarily led by an Explorator of the Mechanicus, therefore an Ark Mechanicus will guide them on their quest to recover anything the Mechanicus can utilize. Perhaps even an STC.

Order of Battle, Indomitus Era
Each of the Chapters Six Companies are commanded by a Captain assisted by Company Lieutenants. In addition each Company posses a Command Squad led by the elected Company Champion who is followed into battle by the Company Apothecary and Ancient Bearer. Company Veterans follow the Captain as his designated bodyguards, depending on the campaign these may range from three to five.

The Company's Warden leads Techmarines as they work to maintain the Company's vehicles and weapons, often standing alongside them will be the Company's Librarian. A Warden's role as both spiritual guide and hardened warrior sees that no Omni Legion campaign doesn't go without the roar of a Warden encouraging his brothers and condemning their enemies to death.

The Omni Legion has taken it upon themselves to create a new Tactical squad equivalent in the wake of Primaris Marines joining the Chapter. Intercessor squads mixed with those who'd normally operate as a Hellblaster, these battle brothers operate in squads of ten, essentially eight Intercessors and two Hellblasters. These 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 barrage.

Beliefs
Should the sacrifice of millions result in saving the lives of billions then the Omni Legion will prioritize the most optimal outcome. This mindset is instilled into even the Chapter's youngest Initiates. Astartes of the Chapter will view subjects of a specific value and should that value be equal or higher than the worth of their objective or another subject then the Astartes will prioritize it. They see nothing wrong with this for everything has worth to the Omni Legion. It is uncommon for the Omni Legion's battle brothers to display care or interest in humans, though this can change depending on the extent of their interactions. Forming some level of trust.

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. The Chapter's reverence for technology has led to their most veteran Techmarines, known as Wardens, to hold the position which would typically be held by Chaplains. The light of the Astronomican as an example of the Emperor's psychic might has led to the Omni Legion believing that the machine spirit is purely an extension of his will which they refer to as the Omnissiah.

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.

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, 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.

Selection
The Adeptus Mechanicus thoroughly spies upon the Hive Cities of Tallon Prime, going as far as to spying on the families that inhabit the cities. It's possible that the children in the lower cities that go missing never to be seen by their families again are kidnapped by the Mechanicus for the purpose of joining the Chapter as either an Astarte or a Serf. Thousands of children vanish from the cities every year so it's unknown how many of these are specifically taken by the Mechanicus.

Tests
Boys are taken away to Tallon Prime's second moon Breyo where they will be subjected to genetic purity tests alongside a series of aptitude tests alongside young candidates training for Tallon Prime's PDFs. It should be noted that the genetic tests for the Chapter have a higher requirement than most other Chapter's due to their Gene-Seed rejection rate. By the conclusion of these trials there are three possible outcomes.
 * First, should the aspirants pass both the genetic purity test and their aptitude tests (of a score above 90%) then they will have earned the right to subjected to Gene-Seed implantation.
 * Second, should the aspirants pass their aptitude tests with a score between 60% and 89% then they will qualify to serve the Chapter as one of their Serfs so long as they are considered genetically pure enough to not be considered a mutant. Serfs that follow the second path will serve the different Serf Offices in commanding positions to lead Serfs of the third path.
 * Third, those who fail their requirements shall continue through their training as per usual. However should the candidate display great potential then the Chapter may recommend them to the Psian Venatores.

Training
Within the VIthCompany the Initiates will be instilled the duty of fighting for the Imperium, ensuring that they understand their roles as weapons crafted by the Emperor of Mankind for this very purpose. Initiates by the end of their time in the VIthCompany are calculated killers expected to follow the chain of command closely and pursue victory for the Imperium of man. Understanding that sacrifices must be made and they will be made.

Genetic Idiosyncrasies/Mutations
There have only been two 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 Astartes 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. This was because of the Chapter's smaller size and higher rejection rate made their Gene-Seed more valuable, now it has become tradition. The addition of Primaris Marines and their genetic purity has ensured the Chapter's ability to maintain a larger count of Battle Brothers due to their higher success rate.
 * 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 block those rays.
 * 2) The Ossmodula: Astartes with this mutations possess a larger than average height, 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 does not appear to show any signs of bone protrusions. It is because of this mutation that the Chapter's Gene-Seed has an average 32% rejection rate, Initiates suffering from an aggressive growth that risks tearing their muscles and slowly killing them. Only the Emperor's mercy can be granted at this point.

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

- First Chapter Master Griffith As a Chapter whose history restricted their numbers so greatly the Omni Legion needed to make up for it with armored support or weapons of greater power than some other Chapters. The Omni Legion 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 Techmarines work every moment of every day to maintain and construct what they can. It is because of this that many guard regiments will be the first witnesses to any new form of weapons deployed by the Chapter, stories of ranging absurdity depending who tells them.

As a fleet based Chapter the Omni Legion is more known for their ship-to-ship engagements. Capturing enemy ships is always a priority should it be of human make, Xeno ships will be reduced to flaming wrecks by the time the Chapter is finished. Those few humans who surrender to the Astartes will presumably be transformed into Servitors.

Each Brother may be assisted in missions by a Combat 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. 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.

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 be put to use as a Scion, 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.

Notable Omni Legionnaires

 * 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 perfect example of what it means 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 with 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 upon the Imperial world of Harmyn which had fallen into Chaos. Dominated by the Lost and the Damned led by Heretic Astartes. Only the fortress continent of Vinasili remained unbroken, protected by both remnants of the world's PDFs and surviving Astartes from the Blazing 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 Lionel - 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 Lionel 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. - Lionel's 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 blade is paired 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. Lionel 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. His leadership of the IInd Company has ensured that his legacy as a genius tactician will stand the test of time, countless ships have been either lost to captured by Vilhelm's forces. -Vilhelm will often take to the field of battle in his custom Cataphractii Terminator armour while accompanied by his Company Veterans. 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 Creighton - Former Captain of the Omni Legion's IIIrd Company, similar to Vilhelm Creighton chose to fight on the front lines with his brothers, intent on spilling the blood of the enemies of man. Considered to be a master duelist that could best most of his brothers, the only one in the Chapter who could best him was Lord Scion Nero. - Despite appearing to be quite ignorant of his enemies the Captain was in truth more fascinated in Xenos than any of his kin, examining some's fighting styles to try to adopt into his own. Encounters with Eldar would sharpen the Astarte's skills, Howling banshees proven to be the greatest challenge presented to him. - Like his brother Vilhelm he felt a powerful thirst for revenge against the traitor forces after learning of Cadia's fall and the presumed destruction of their kin from the Ist Company, intending on leading his Chapter to victory. Captain Creighton died in a campaign mere weeks after the Chapter first encountered Roboute Guilliman and the new Primaris Marines, Captain Logan fought alongside him as both were trained well in the art of melee combat. Logan and Creighton lead the Chapter's Close Support forces against Khornate Berserkers. In the height of the battle Creighton would fall to a Greater Daemon of Khorne...the beast slain by Captain Logan who managed to smash the Daemon's head with his power fist.


 * Captain Aegeus - Like Lionel of the Ist Company, Aegeus is one of Awakened within the ranks of the Omni Legion. The Omni Legion chose to indoctrinate the Primaris as soon as they could, now with their limitation of numbers removed the Astartes adopted these new brothers with ease. Aegeus was chosen from the ranks of the Unnumbered Sons for his battlefield experience during the events of the Indomitus Crusade. Initially Aegeus was welcomed as a new Lieutenant of the IIIrd Company until the passing of Captain Creighton. - Unlike his fellow Captains of the Chapter Aegeus commands his Company from a distance, using his Lieutenants as field-based communications officers as to relay him enemy responses and updates. Rather than leading his soldiers onto a campaign of blood and carnage like Vilhelm of the IInd Company Aegeus prefers to lead his men with a more calculated method, testing their foes to adapt and counter all their tactics.


 * 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 IVth 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 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 Vth Company has lived for millennia as a powerful Contemptor Dreadnought. Supported by the Company's Techmarines and Mechanicus Enginseers he has led the Company for roughly 3000 years. - Tristan has always stood in the front lines with his men, refusing to put them into dangers he himself wouldn't put himself through. His ancient 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. - As the millennia passed after his ascension to entombment 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. Tristan became very close to the Magos Domina Mira as she took over his maintenance in early M41. Tending to him every moment she gets, viewing him as an idol the Machine God himself. Tristan sometimes speaks of his angel, a woman who saved him from death.


 * Captain Gael - The strict and seasoned Captain of the VIthCompany 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 VIthCompany rather than joining the Lord Scion. - 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.


 * Lord Apothecary 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 during the events of the Indomitus Crusade which resulted in losing his left arm and his mind being split into two different personalities. Vinland finds himself tempted to seek out traitors to kill with his own hands, this new dormant personality manifesting itself in the presence of Chaos.


 * Reclusiarch Vamos - As expected of his position the grizzled Master of Relics defends the inner sanctums of the Chapter's Vault, leaving should he be tempted to gain further knowledge and discover further ancient weapons and armour by aiding the Lord Scion. Vamos is a skilled warrior risen from the ranks of the Chapter's Wardens, his thirst for knowledge possibly surpassing them after the appearance of the Great Rift.


 * Lord Warden 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 Techmarines be insufficient. -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 the Fabricator-General of Roitheta. 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.


 * Lord Librarian 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 humanity's 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 peel the armour from any foes that stand in his way, he is a master of Technomancy. -The Lord Librarian 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.


 * Lord Scion Nero - Very little information is available about this individual. Nero will be assigned tasks by the Chapter Master or Fabricator-General. The earliest records of Nero strangely begins when he attained his position, it's suspected that his name was changed when he was elected to become the Chapter's Lord Scion. He along with the other Scions of the Omnissiah would not aid the Chapter during their campaigns against the forces of Chaos following the destruction of Cadia.


 * Chapter Master Griffith - The original Chapter Master of the Omni Legion, he as would his brothers fought alongside Imperial Forces to drive off an Ork WAAAGH! Near the end of the long campaign Griffith stood atop the Ork citadel holding the severed head of the Ork Warboss, declaring victory of Imperial forces. -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 Battle Companies struck enemies upon nearby worlds, cutting them off from another. During the battle the Ork Warboss fought Griffith, the pair during their duel fell 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 so to this very day he is categorized as MIA.


 * Chapter Master Artorias  - Artorias has been the Chapter Master of the Omni Legion for 200 years, previously the Captain of the IVth Company. Artorias has always presented himself as a figure of authority going as far back as to his time in the VIthCompany. Strategies that prioritize low casualties while maximizing enemy fatalities require a tactical genius which Artorias has proven to possess. 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 should order their men to do what they themselves would not. - Despite this he adopted another important role of Chapter Master, commanding Tallon Prime's PDFs, reorganizing city work forces. Yet Artorias allows the Hive City Viceroys the freedom to control as they wish, so long as they maintain proper efficiency -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.


 * Warden Royce  - Royce has spent most of his career in the Vth Company as one of the most venerated Techmarines 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 Vth 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 Firstborn Astartes in the Omni Legion becoming promoted to the Ist Company thanks to their efforts in fighting back against the dark. Royce would be chosen to part-take in the Rubicon Primaris, becoming faster and stronger than he was before. This was another test orchestrated by Tristan and Magos Domina Mira.

Chapter Fleet

 * Blade of the Omnissiah (Battle Barge) - Countless war zones have been cast in this ship's shadows from orbit before raining drop pods to the surface. It may not be a ship specialized in ship-to-ship combat but it is far from incapable of doing so, especially when aided by several other support vessels. As the Chapter's first Battle Barge it was also the Chapter's original Fortress-Monastery for a time.
 * Greater Dominion (Battle Barge) - Fleet Master Vilhelm's personal Battle Barge, leading the Chapter's space forces to fight off any and all intruders that make the mistake of entering their home Sub-Sector. Over the generations the IInd Company would make many upgrades and modifications, transforming it into a terrifying warship.
 * Immortal Servant (Battle Barge) - The origins of this ship are seemingly unknown, it appears that the Chapter gained possession of this ship sometime in the early 38th Millennium. The former heraldry stripped from it's halls and exterior to be replaced by that of the Omni Legion. Truly a magnificent ship whose former masters were unworthy. Death and destruction follows the warriors of the Omni Legion's IIIrd Company for that is all they give.
 * Boundless Execution (Strike Cruiser)
 * Fiery Invocation (Strike Cruiser) - A ship belonging to the Ist Company that was sent to aid Imperium forces against Abaddon's 13th Black Crusade only to disappear for nearly a century. Once reappearing it did so under the command of Lieutenant Fenix with only a fraction of it's Veterans remaining while most of it's non-Astarte crew had survived.
 * Harrowing Hunter (Strike Cruiser) - Appearing within the Omni Legion's fleet sometime in late M41 it's suspected this Cruiser was obtained from another Space Marine Chapter, the identity of which is unknown. All that is known about the unidentified Chapter is they had intruded onto the Omni Legion's territory and refused to stand down, their ship was boarded and their entire crew slaughtered as a result.
 * Iron Majesty (Strike Cruiser)
 * Obsidian Fury (Strike Cruiser)
 * Shrouded Intent (Strike Cruiser)
 * Advent to Victory (Vanguard Class Light Cruiser)

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:''


 * Avenger: One of the Chapter's Drake Blades gifted to them by the Blood of Vulkan, in the careful hands of Lord Scion Nero who is one of the few capable of wielding such a mighty weapon one-handed. Nero has demonstrated flawless skill with the weapon given his role.


 * 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 Lionel of the Chapter's Ist Company.


 * Heaven and Hell: A pair of Lightning claws that were discovered by the Vth 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 one hundred years being purified by the Chapter's Techmarines 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.


 * Helm Breaker: Another one of the Chapter's 20 Drake Blade relics, 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.


 * 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 taken down by well placed shots. Chosen from the vault by Captain Gael once he was given the rank of Captain, the true origins of these pistols were lost.
 * The Omnissiah's Fist: a relic that has been held within stasis on board the Ark for thousands of years, the last to wield it in battle was none other than Captain Tristan before his internment inside his Dreadnought chassis. A powerful Thunderhammer that has struck down countless Xenos, shattering their bones to dust and vaporizing their flesh.


 * Strife: A second relic wielded by the VIthCompany's current 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 Techmarines and their Tech Priest allies.


 * Land Raider Achilles


 * Cerberus Heavy Tank Destroyer


 * Mastodon


 * Sicaran Battle Tank

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. Unlike most Chapters the Omni Legion's Companies do not utilize Company trim colours on their pauldron, rather they mark Companies with the number on the Battle Brother's left knee while their squad number is upon their right pauldron. 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.

Allied Chapters

Salamanders
Relations between the Salamanders and the Omni Legion has always been something akin to a teacher and student. The Salamanders outlook on their Serfs and the Imperium’s citizens influenced the Omni Legion's ideals early on thanks to their first contact. The Chapter sometimes 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. Fighting alongside the Salamanders has become one of the greatest honors among the Omni Legion.

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 IVth or Vth Companies to support the Ashe Knights if threats such as the Tyranids or Orks are present.

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. 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 21st 'Cursed' Founding, the Omni Legion sees the Astartes of the Blood of Vulkan as reliable allies. Omni Legion has been gifted twenty 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. The Omni Legion holds these Drake Blades dearly for only the Company Champions, Ist Company Captain and Chapter Master are permitted to wield them.

Should the Omni Legion require additional arms against the green-skinned Ork menace they just may call upon 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 can breath fire when threatened by Orks.

Conflicting Chapters
"They fight for our glorious Emperor but they threaten that which belongs to him. I'd rather fight alongside a filthy hound of Russ than one of those brainless curs!"

- Captain Vilhelm speaking of the Marines Malevolent

Marines Malevolent
The blatant disregard and hostility these Astartes toward allied Imperial forces 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.

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 consider 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 the 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.

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 respect for the forces of the Astra Militarum for facing such unbelievable odds.

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 naval base.

Adeptus Mechanicus
Thanks to Roitheta giving 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 Techmarines that serve on board the Ark one could mistake the entire Chapter as followers of the Machine Cult.

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 willingly cooperate 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 influence the Omni Legion has bled into the Order, reshaping them 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 home, entrusted with the protection of the world's people as so the Astartes may focus their forces on more important matters that take them far from home.

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. Despite how battle brothers may feel the power and influence a single Inquisitor possesses is to be respected by any.

Upon the Chapter's official Founding 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 withheld by the High Lords. Chapter Master Griffith was confronted by two of these Inquisitors while the other Astartes were still preparing to leave Roitheta in search of a recruitment world. Unsatisfied with their answers they reported to Grandmaster Theodore Holoserica who agreed that this Chapter's origins were suspicious.

The only two Ordo that the Omni Legion will frequently cooperate with are those of the Ordo Xenos and the Ordo Machinum. The former through the service of Deathwatch recruits and the latter in the case of the Chapter's Scions of the Omnissiah. In most recent years one of the few Inquisitors to gain the trust of the Omni Legion is that of Inquisitor Hildebrand, member of the Ordo Machinum and one that can consider Lord Scion Nero as an acquaintance.

Rogue Traders
These intergalactic merchants and travelers are no strangers to the Omni Legion who seeks them out for their valuable finds. 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 fragment they wouldn't hesitate to slaughter them all.

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 are given a warm welcome as allies to the Chapter, meals provided by the Chapter's Serfs. 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 fleet.
