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 allies itself closely with the Adeptus Mechanicus, several other Adeptus Astartes Chapters, and the Adepta Sororitas Order of the Sacred Flame. They pride themselves as protectors of both the Imperium's people and mankind's history as they seek out technologies thought lost and protect what mankind already has.

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.

Founding
Early in M34 a Space Marine Chapter would appear to aid 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 battle. Several years would go by until eventually the 7th Founding would come to pass which saw the Omni Legion's name recorded within it's few records.

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 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 that would host their Fortress-Monastery. The Omni Legion would seemingly vanish from the galaxy for several centuries as they established themselves proper.

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 original 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.

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.

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. 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 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 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.

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 Chapter rarely risks 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. Although should the death of millions save the lives of billions then the Chapter will prioritize the most optimal outcome.

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 Techmarines, 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.

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. Ancient Hive cities house the majority of the planet's population. Other methods of recruitment are from offerings provided by the people from worlds the Chapter visits, 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 even 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 with another to test how pure their genes are. Should any of them display one condition that could be a result of inbreeding 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.

Training
As expected of the Adeptus Astartes the Omni Legion's training is strict and detailed, taking each aspirant into account to determine their weaknesses and work from there. If a child is more notable for their physical aptitude then they'll be presented with more problem solving tests than a child who would excel at such who in return will be pushed through more physical tests. The goal of this is to create Initiates that are nearly equals in all fields before the next step of their training.

Before an Aspirant would even hear of Gene-Seed they'll be subjected to days of psycho-indoctrination, purging their mind of their past life events. Once completed the young men become nearly hollow vessels, only truly retaining any previous psychical or psychological training. A minor test formulated by the Mechanicus and the Chapter's Techmarines would be to supply damaged devices of little worth to these Aspirant to determine who may display an aptitude in repairing technology. Teaching them early on the worth of mankind's technologies and the value of patience.

Within the VIthCompany the Initiates will learn quickly to value the aid of humans in the form of Guardsmen, required to fight alongside them often. Sergeants will instill the duty of fighting for mankind into the Initiates, 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.

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 6 Companies. A single Veteran Company, two Battle companies, two Reserve Companies and the Scout Company (dubbed the Initiate Company). The IInd and IIIrd Companies 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 Chapter's Battle Companies 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.

Aspirant
The children inducted into the Chapter at a young age, many will be taken from the Slums of Tallon Prime's Hive Cities while others are chosen from boys being trained by the world's PDFs. The Adeptus Mechanicus thoroughly examines these children, going as far as to spying on the families that inhabit Tallon Prime. 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 Companion should they fail the initial tests.

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 they can while they serve on the front lines.

Should the Captain the VIthCompany 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 VIthCompany. For example, should three members of the squad die then the two survivors will spent 3 years back in the VIthCompany.

Battle Brother
Astartes who complete their training in the VIthCompany will finally achieve this rank, proven to be warrior of the Emperor. Once finished with their service to the IVth and Vth 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.

The Omni Legion has taken it upon themselves to create a new Tactical squad type 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.

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 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 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. Each Librarian is trained to

Librarian Dominus (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 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.

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. The importance of the Chapter's Wardens cannot be stressed enough with their close relations to the Adeptus Mechanicus. They lead 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 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 Scion Dominus (Chapter Champion) 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.

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 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 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 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.

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.

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 words of the Warden and the sight of the Ancient is 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 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 sparred 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 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. In place of Company Champions it is the duty of the Chapter's Honour Guards to challenge enemy commanders and defend the command force in the thick of battle, cycling into Chapter Companies between campaigns.

Scions
The few who survive their service to the Deathwatch serve the Scion Dominus (Chapter Champion) 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 Scion 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.

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.

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 Techmarines 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.

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 the other Companies.

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 Techmarines 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 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 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.

IInd Company and IIIrd Company
Both Battle Companies are 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 stretching firing positions from established defense lines. Holding the line for as long as possible before falling back, allowing Close Support squads to step in and engage the foes while fallen back Battleline Squads cover them.

Borrowed Initiate squads assist in the evacuation of civilians as a means to ensure their safety in case the defense line is broken, working to get everyone either off world or in shelters as quickly as possible before joining the fight. Fighting 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 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.

Many Servitors join the front lines with Astartes to carry additional equipment or assist with 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. 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. Unlike the IVth Company who hold strategic locations the Vth Company is an offensive focused force that will rarely hold a position for long periods of time beyond required repairs.

VIth Company
The VIth Company operates in Semi-Companies, each led by the Company Lieutenant with an equal number of Apothecaries assigned to each 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.

In recent years the Company's Captain begun leading a force of Primaris Vanguards 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.

Scions of the Omnissiah
This group's actions are mostly unknown to even the Chapter's Captains, most battle brothers will never see the Scion Dominus 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. It is rumored that any Scion carries more power and authority than the Chapter's Captains who are left in the dark, knowing nothing of their mission.

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
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 alongside any Magos Dominus/Domina present.

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. 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
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 to the Chapter's smaller size and therefore Gene-Seed was more valuable, now it has become tradition.
 * 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 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 don't appear to show any signs of bone protrusions.

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 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.

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 forged the Omni Legion's ideals early on thanks to their first contact. 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. 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 aid the Ashe Knights in the defense and evacuation of civilians 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. 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.

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 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 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 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 closely withheld by the High Lords of Terra. 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. He was questioned for hours and much of what he told them was information given to him by Fabricator-General Aliya in advance. 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 of an obsession.

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 fragment 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 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.

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 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 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 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 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 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. 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 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 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 Vth Company has lived for millennia as a powerful Contemptor Dreadnought. Supported by the Company's additional Techmarines 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. -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 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 Scion 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 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 Scion Dominus. Vamos is a skilled warrior risen from the ranks of the Chapter's Wardens,


 * 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 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.


 * 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.


 * Scion Dominus Nero - Very little information is available about this individual. Nero's role doesn't place him as a typical Chapter Champion, instead Nero will be assigned tasks by the Chapter Master or Fabricator-General. The earliest records of Nero strangely begin when he attained his position, it's suspected that his name was changed when he was elected to become the Chapter's Scion Dominus. 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, hand picked from the original 200 Astartes 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. He would lead the Chapter to fight alongside Imperial Forces to drive off an Ork WAAAGH! Near the end of the long campaign Griffith stood atop 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 other Companies fought off the surrounding forces. 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 165 years, previously he was 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. Artorias is dedicated to his role defending the people of the Imperium, nearing dying as he protected a squad of Guardsmen in his early career. 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 order their men to do what they themselves would not. -Despite this he adopted another important role of Chapter Master, hearing the people. Should the Ark find itself orbiting the world of Tallon Prime Artorias will see to it that he hears the woes of the people if he deem the governors actions lacking. Spending days commanding Tallon Prime's PDFs, reorganizing city work forces, and inviting the noble families of the Hive Cities for their blood connection to the Omni Legion proves they're worth listening to. -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 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 Scion Dominus 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 as the Chapter's greatest warrior.


 * 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 100 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.


 * 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 thoroughly modified by the Chapter's Techmarines and their Tech Priest allies.


 * Land Raider Achilles


 * Cerberus Heavy Tank Destroyer


 * Mastodon


 * Sicaran Battle Tank

Chapter Fleet

 * Blade of the Omnissiah (Battle Barge) - Death and destruction follows the warriors of the Omni Legion's IIIrd Company for that is all they give their foes. 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.
 * 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. Gifted to the Chapter during the period they became fleet based. 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.
 * 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)
 * Iron Majesty (Strike Cruiser)
 * Obsidian Fury (Strike Cruiser)
 * Shrouded Intent (Strike Cruiser)
 * Advent to Victory (Vanguard Class Light Cruiser) 

Notable Campaigns
''Local files held by the Chapter are missing, such records are still held by other departments of the Adeptus Administratum.

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.
