## Chapter History

### The Moirae Schism (Early M35)

The earliest records of the Chapter's history were lost during the Moirae Schism; the Omni-Legion's leadership split between loyalties to the Imperium and Moiraean radicals. A Chapter-wide purge of Moiraean followers took Astartes and Serfs, led by Captain Garland. The Honour Guard divided; those who stood with Captain Garland became the Praetorian Guard, led by the Lord Praetorian, the loyal Chapter Champion. Elected to lead the loyalists as Chapter Commander, Garland personally executed the traitorous Chapter Master. The raging void battle destroyed several Strike Cruisers, one bearing the Chapter's Librarius, destroying the Chapter's recorded oldest history. The ranks of Techmarines were culled; only the few willing to slay their traitorous Brothers were spared and offered redemption.

Garland reorganized the Companies into the more recognizable Orders the Omni-Legion uses today. The Apothecarion and Librarium remained the same; the Armoury and Reclusiam combined into the Technicarum. Once Chaplains, the Wardens command the Technicarum and the Techmarines they oversee. All future Techmarines are closely watched and tested, ensuring a Mars-influenced Brother retains an unbreakable loyalty to the Imperium. The rank of Lieutenant, not heard since the Horus Heresy, commanded the smaller Conclaves sent hunting into the void.

The Omni-Legion fought in the Gulf of Black Shadows fleet war for centuries, continuing to exterminate Moiraean Hereteks. The number of vessels captured by the Omni-Legion at this time gained them the reputation of boarding specialists. One vessel captured was a massive Battle Barge, dubbed the Grand Providence, becoming their Fortress-Monastery.

### The Charadon Crusade (671.M38-723.M38)

The earliest events of the Charadon Crusade were the discovery of Orks advancing their territory, moving to the Galactic West, into the Moriana system, a Fortress World charged with reinforcing the border between Imperial space and the Charadon Sector. The Omni-Legion assisted with defending the system as additional Imperial forces arrived. Regiments and Battlegroups of the Imperial Navy consolidated here shortly after word of further Ork incursions reached the defenders. Multiple Ork fleets had begun assailing Imperial worlds, stretched along the territory's border. Fearing such an event as the War of the Beast repeating, the High Lords of Terra ordered that the Xenos be crushed as quickly as possible.

The Charadon Crusade began by holding back the green tide; it wasn't until the Inquisition granted use of the Deathwatch that progress was made; the assassinations of Ork Warbosses contributed to this significantly. The Order of the Sacred Flame fought the Orks with the same steely resolve as the Astartes, burning the Xenos to ash. Imperial Navy vessels tore into Green-Skin ships, boarding actions attempting. Many Astartes in the Omni-Legion died during this brutal conflict; even after losing half their number, they continued to fight on the front lines. After losing their Chapter Commander, the Omni-Legion dropped out of the Crusade for a decade to rebuild their losses.

At the Crusade's height Imperial forces consisted of numerous Astartes Chapters, Guard Regiments and Titan legions. Chapters consisted of: the Omni-Legion, Immortals, Bones of Noth, Draconian Impalers, Imperial Wardens, Angels of Anguish, Steel Outriders and more. Guardsmen regiments include the Avestan Jezzalier Guard Corps, Tallon Chem-Drakes, Corsaegan Cuirasseurs and Keltan Mechanised Guard.

The Charadon Crusade eventually concluded, allowing Imperial forces to withdraw their bloodied regiments and ravaged Chapters. The Omni-Legion was gifted a second Battle Barge for their commitment to the Charadon Crusade, having spent the lives of hundreds of Battle-Brothers. The Indomitable Vigilance joined the Chapter as a valuable asset, becoming a base of operations for the Chapter’s Apothacarion and Scout Order.

## Chapter Organisation

The Omni-Legion is a semi-Codex divergent Chapter, utilizing six Orders rather than the traditional ten Companies. Combining their Battle Companies into Battle Orders and Reserve Companies into Support Orders. The Veteran Order, two Battle Orders, two Support Orders, and the Scout Order. One Captain leads each of these Orders; the Legion-era Lieutenant rank was reintroduced to command the demi-company-sized forces called ‘Conclaves.’ For instance, two Conclaves make up the Veteran Order, while each Battle and Support Order requires four Lieutenants for their Conclaves.

Conclaves are used as strike forces to pursue their prey or provide immediate support to nearby Imperial forces. Specialist Conclaves exist in the form of Assault Conclaves that prefer fast assault tactics or Devastator Conclaves that field deadly ranged weapons of war. Each is supported by their respective Gunship and Battle Tank squads.

The Primaris Marines have increased the Chapter’s ranks to a consistent one thousand Battle Brothers with few rejections. Since the Primaris Marines’ implantation, the Battle and Support Orders have maintained a stable two hundred Battle Brothers, while the Vanguard Primaris reinforced the Scout Order. Their strategies were once out of caution to protect the Chapter's precious Gene-Seed; now, they purge the Imperium's foes with ferocious efficiency.

### Chapter Command

* **Chapter Commander** - As the master of the Omni-Legion’s fleets, Chapter Commanders are tactical geniuses and experienced warriors capable of assessing a void battle with a glance. Upon the Chapter Commander’s death or internment, an election is held among the Chapter’s council to determine who should take his place.

* **Lord Praetorian** - This warrior stands alongside the Chapter Commander as a weapon of war to be unleashed. A Lord Praetorian focuses on slaughter, constantly analyzing those he encounters without a whisper.

* **Praetorians** - The greatest warriors in the Chapter, tasked to guard the Chapter Commander. Each wields master-crafted weapons and Artificer armour; some are gifted ancient Terminator plate. Praetorians may join Chapter Orders as temporary Champions to hone their skills. Upon returning, they will pass their knowledge to their fellow Praetorians.

* **Lord Warden** - As Master of Sanctity, a Lord Warden ensures that all within the Chapter’s ranks demonstrate unflinching loyalty to the Emperor. Their armour and weapons are rivalled by no other within their ranks, seconded only by the weapons they craft. The Lord of the Technicarum oversees the maintenance and construction of the Omni-Legion’s wargear.

* **High Warden (Reclusiarch)** - The Guardian of the Ancients, prepared to cut down any that bears no mark of the Omni-Legion. This rank is appointed by the Lord Warden, chosen to be his successor, though he is to spend this service awaiting his master's death. Onboard the Indomitable Vigilance, the High Warden lurks in the darkness, passing his knowledge onto his Brothers and leading them in their daily rituals and protect the Omni-Vault.

* **Lord Librarian** - Master of the Chapter's Librarius, curator of the Chapter's collected knowledge. He leads the Chapter's research into Technomancy, believing the Machine Spirit is connected to the Emperor of Mankind himself. The Lord Librarian will exorcise daemonic entities from machines they recover from the Cursed and the Damned, mending the tattered Machine Spirit or bringing it to heel.

* **Lord Apothecary** - instilling all his knowledge into his students, ensuring each can successfully implant the Chapter's Gene-Seed. Younger Apothecaries remain stationed on the Jungle Death world of Menace, aiding Scouts and Gene-Seed implantation procedures under his guidance.

### Order Command

* **Captain** - These Astartes are masters of warfare, many hardened by centuries of war and gifted with ancient weapons that decimate the foe. They are capable commanders who utilize the valuable information gathered by their numerous Sergeants and Lieutenants to formulate various strategies.

* **Warden** - In the aftermath of the Moirae Schism, the Chapter’s surviving TechMarines vowed to serve under the remaining Chaplains. Wardens replace the rank of Chaplain to ensure that the Chapter's Technicarum instils a steadfast devotion to the Emperor into every TechMarine. One of the requirements to become a Warden of the Omni-Legion is to renounce any vows to the Machine Cult.  Chapter Librarians will be present during these to read the TechMarine's soul to ensure they’re genuine in their words. Warden Aspirants, called Postulants, stand vigil onboard the Indomitable Vigilance, taking an oath of silence in the Hall of Ancients; their skull-faced helmets are crafted to detect speech from the wearer. The purpose is to cast aside the Martian tongue.

* **Librarian** - Technomancy is a powerful skill in the Chapter, allowing them to converse with the machine spirit. Minor Librarians are responsible for recording the victories and losses of the Chapter. Full-fledged Librarians will join any of the Orders to lend their services as warriors and Technomancers. Librarians who study the psychics of Technomancy can rouse or soothe the machine spirit, tending to the weapons of allies or disabling enemy tanks. Against traitor Astartes, a master of Technomancy can shut power armour down with little effort. Transforming power armour into an Astartes-sized prison locked to their flesh, simply cutting off their heads to acquire their armour without damage, becoming a horrifying reality to the victim.

### Conclave Command

* **Lieutenant** - Masters of the Conclaves, each falls under the command of their Captain, who may entrust them to perform other duties. Omni-Legion Conclaves have been across the galaxy, many aiding Rogue Traders, Mechanicus Explorators or Inquisitors of the Ordo Machinum.

* **Techmarine** - As a Chapter closely associated with the Adeptus Mechanicus, the Omni-Legion has a higher-than-average number of Techmarines. Each leads a trio of Battle Servitors to war. Techmarines can crush and tear apart their foes with their Servo-arms, Omnissian Axe cleaving thick carapace and durable power armour.

* **Apothecary** - Apothecaries are notably more vicious after years spent protecting their Neophyte Brothers against Feral Orks. This brutality follows the Apothecaries as interrogators, torturing prisoners to near death until they reveal everything the Chapter wants to know, even if it means extensive use of their Omophagea.

### Battle Ranks

* **Veteran** - Centuries of service and thousands purged in the Emperor's name have honed these Astartes into beings worthy of the terrifying weapons they wield. Fighting together in kill teams of various dispositions.

* **Sergeant** - Leading their Brothers through the battlefield in any world. After a Battle-Brother achieves this rank, he will be gifted a relic from the Omni-Vault.

* **Brother** - When one has earned the right to be called Astartes, they will do so in the Support Orders. After decades of service, they'll move onto the Battle Orders or one of the multitudes of specialist ranks.

* **Scout** - Scouts are the crux of Chapter assaults, and their intel ensures any attack from the Chapter is swift but devastating. Scouts scramble enemy communications and sabotage defences—even assassinating or capturing enemy commanders.

* **Neophyte** - An Aspirant that has entered the early stages of Gene-Seed implantation.

### Specialist Units & Formations

* **Dominator Squads** - Consisting of Intercessors and Hellblasters, they clear halls brutally efficiently during boarding operations. Heavy Dominators are a variant that consists of Heavy Intercessors and Eradicators. The decision to create this Squad type was to add flexibility to the Primaris, more akin to Firstborn Tactical squads.

* **Purgator Squads** - Formed during the days of Garland, these ruthless Astartes charge into the foe with chainswords that tear through bone and flesh; some armed with flamers or melta weaponry designed to eradicate any trace of their target. In the millennia since Garland’s death, Purgators have only continued to purge Orks, Tyranids, and even followers of Nurgle.

* **Tactical Scout Squads** - As a fleet-based Chapter, the threat of combat in the void is ever-present. Most Scouts will receive their Black Carapace before their first Scout Expedition, supporting more experienced Brothers during enemy boarding actions. These suits remain unpainted to signify their position in the Chapter, easily identified among Brothers.

* **Apollyon Terminators** - Wounded and heavily bionic veterans that struggle to keep pace with their Brothers become Apollyons. These specialists operate in squads of variable sizes depending on the Veteran squads they serve. Sealed within a life-supporting Terminator plate, Apollyons arrive in the thick of battle in response to teleport-homing beacons. Wielding the terrifying might of Phosphex and Plasma weapons, they render infantry to ash and armour to smouldering slag.

## Logisticiam

* Serfs are chosen from the populace of worlds visited by the Omni-Legion, joining thousands of others who live to obey their Astartes masters. Despite a strict screening process, the life of a Serf is considered fair. Each Serf to join the Omni-Legion’s ranks will be marked, and a crimson half-gear will be tattooed around their right eye socket. Serfs are rewarded with extra rations should they report or turn over any unmarked stowaways or void born they find hiding in the depths of their vessels.

* Villeins are better trained than most Serfs in the Omni-Legion; their martial skills are considered above the average Guardsman. Responsibilities include protecting Equerries or enforcing Serfs when necessary. Chosen among the Chapter’s multitude of Serf Offices, they are sought for their history of skill at arms and understanding of the Machine Spirit. While it is typically the Astartes who defend their vessels, it falls to the Villeins to fight alongside the Battle Servitors in the Astarte's absence. Once a Serf becomes a Villein, they are bound to the void, never to spill blood on a world. Astropaths and Navigators will be treated as royalty among the Omni-Legion, particularly the Navigator Houses of the Apocrypha Sub-Sector. Navigators are assigned an Astartes guardian, while the crimson-armoured Villeins protect Astropaths.

* Equerry is a title granted to a Serf who has gained great renown among their ranks. These natural leaders show a steadfast loyalty to the Imperium. With heads held high and a Laspistol on their hip, they stand alongside their masters, becoming aide and novitiate. They are tested with questions and scenarios. Akin to the relationships between an Astartes Captain and his Lieutenants. Any Equerry to outlive their master will pass the knowledge they have gained onto Serfs of the Technicarum, Apothecarion, and Librarius.

## Apothecarion

Every Chapter vessel has an Apothecary presence, but within the Indomitable Vigilance lies the Apothecarion. Neophytes receive the Chapter’s Gene-Seed, among numerous forms of psycho indoctrination. Apothecaries oversee all these procedures, cutting open and transforming youths into the same weapons of war. Medicae Serfs will assist through any means necessary, to the approval of their masters. Going so far as the breaking limbs of Aspirants proving too uncooperative or hostile.

Apothecaries will interrogate the traitor and the Xeno in the coldest depths of the Battle Barge. Pumping them with drugs to prevent sleep and enhance their agony as their interrogator pushes what physical torture their subject can endure before breaking. Scout Conclaves will be sent into the void based on information attained from these methods, discovering enemy strongholds or worlds of strategic value.

## Librarius

A repository of knowledge millennia old, preserved and expanded by each Lexicania of the Librarius. Battle reports are written and submitted for approval to the more powerful of this brotherhood, the Codiciers. Codiciers will be summoned to the Apothecarion to assist in interrogating prisoners and assessing recruits. Epistolary, often just called Librarians, are trained extensively in the psychic disciplines in Technomancy, capable of locking Heretic Astartes in their armour or banishing the taint of a Daemon Engine. Omni-Legion Librarians will tend to the machine's soul while their TechMarine brothers mend the body.

The union between the Librarius and Technicarum bears Psy-Bonded Familiars, cybernetic constructs of various designs and functions. Some may specialize in data extraction, others in tearing the foe apart limb from limb. Technomancy allows Librarians to control their Familiars like an extension of their will.

## Technicarum

Within the Omni-Legion’s mobile Fortress-Monastery, the Grand Providence, is the Technicarum, a hub of production and restoration. The Chapter’s Armoury and Reclusium combined into a single order, commanded by TechMarines and their Warden overseers. Technology is essential to the Chapter; the Technicarum oversees the repairs and maintenance of the Chapter’s weapons, armour, and vehicles. Only through petitions to the Technicarum will many war machines leave their protection to destroy their foes—blessed by the Lord Warden and his Order.

A Chapter’s Armoury is ordinarily thick with smoke and heat that deprives many mortals of a long lifespan; this remains true for those Serfs who serve the TechMarines. Older servants who prove their worth to the Chapter are rewarded with augmentations to survive easily. Only fully-fledged Battle Brothers may enter the Technicarum without reprimand; Serfs that gain entry must do so through the guidance of a guardian.

## Hall of Ancients

Within the shrouded darkness of the Indomitable Vigilance’s Hall of Ancients hosts the sleeping Chapter Ancients. Resting for decades or centuries until they are summoned to war while guarded by the Chapter’s Postulants. If one attempts to enter without a guide, they will be cut down without a word. Any time one of the Chapter’s Orders petitions the aid of a Dreadnought, they must relay this to the High Warden, master of the Hall of Ancients. Overseeing the duties of his Postulant brothers, he ensures each Dreadnought sarcophagi is undisturbed and tended to.

This chamber's vast walls and ceiling are lined with countless banners lit by numerous lantern Servo-Skulls. Their dim lights are constantly in motion, acting as beacons for those granted entry or revealing the beautiful banners kept from the filth of battle. Sharp-eyed individuals have sighted ancient standards from other unidentified Chapters in this collection for preservation before their owners can be uncovered.

## Combat Doctrine

An Omni-Legion assault will begin by dispatching Scouts to assassinate or capture military and political leadership, sabotage planetary defences and sever communications. The Chapter fleet will strike, drawing all eyes skyward as they ravage orbital defences. Panic sets in the civilian and military populace before the Astartes even reach the surface. At this time, Chapter Scouts make most attempts at resistance doomed from the beginning.

During ship-to-ship engagements, the Omni-Legion will strike with vicious boarding squads, often targeting the command deck and enginarium. It is not unusual for the Chapter to capture frigates to add to their fleet, even cruisers in some rare cases. Private vox communications and battle signs silence their boarding actions, aside from the roar of their chainswords and explosions of bolt rounds. Many humans who surrender to the Astartes will be transformed into Servitors after their Apothecaries thoroughly interrogate them.

Orbital bombardments signal an Omni-Legion planetary assault; weapons target military strongholds and armouries. Deathstorm Drop Pods rain down; Thunderhawks soar toward the surface, and Astartes will quickly overwhelm the defenders. Battleline squads with Support squads vanquish the foe with coordinated assaults as they flank or break the enemy’s defences. Thunderhawks bring Battle Tanks, Bikes and other Transports to the surface to add their devastating weaponry to the Astartes.

Once the Omni-Legion has extracted all its assets, its fleet will begin a final orbital bombardment. Targeting locations the Astartes attacked, destroying what remains of their carnage in a hail of radiation and plasma. The enemy left nothing to gleam from their violent assault save the scoured hellscape.

## Deathwatch Service

Since the Deathwatch’s Founding, the Omni-Legion has done what it can to supply its most skilled Battle Brothers to combat the Xeno. The Chapter’s technical expertise has led Deathwatch Kill Teams to seek Astartes similar to the Omni-Legion. Their history has seen them clash against the Orks for millennia, so the green-skins are no strangers to the Omni-Legion's Battle Brothers.

Splinter Fleet Zurvan tested the entire Omni-Legion Chapter against the Tyranid lifeform; within their ranks, still breathing, are those brothers who fought to protect their recruitment world. These Tyrannic veterans lend their skills and knowledge to the Deathwatch, their territory's borders feasted upon for years.

## Chapter Culture & Beliefs

"*There is no honour nor glory. Only death awaits the complacent and vain. Strive for victory above all.*"
— Omni-Legion Dogma.Pragmatic in nature, Battle Brothers treat honour or glory as a hindrance to achieving their goals. No strategy is considered shameful or cowardly. Worship of the God-Emperor is frowned upon among the Omni-Legion's Battle Brothers. However, it is not forbidden. So long as the Brother’s faith doesn’t blind them to their duty to the Chapter.
Bionics are granted only to those who sacrifice their flesh and bone to serve the Golden Throne. The Chapter isn’t lacking in such technologies; they show restraint in using them. The reclamation and preservation of technology are of the utmost importance to the Omni-Legion, even sending Conclaves to deliver relics to their original owners. As such, the Omni-Legion has been across the galaxy. Rarely will they engage in Space Hulk exploration, instead preferring to target vessels closer to their size due to their ease of capture or destruction in comparison.

## Chapter Recruitment World

    Located on the eastern edges of the Niphilum Sector, within the Apocrypha Sub-Sector, Tallon Primus is a tidally-locked world; Hive Cities exist only within the Lunar Region, and the heavily irradiated Solar Region hosts a desolated desert. The Omni-Legion takes its recruits from the vast PDF academies of each Hive City; in exchange, the world has its tithes eased. With these reduced tithes, the planet's PDF forces swelled; the Mechanicus of Roitheta supplied the regiments with additional weaponry and munitions. In addition, Hive cities constructed powerful anti-aircraft cannons that force most enemies to attempt landing in Primus’s hellish Solar region.

In 995.M41 Splinter Fleet Zurvan devastated numerous Hive Cities and trapped billions in quarantine regions. The Adeptus Mechanicus of Roitheta aided the Inquisition in establishing quarantines through deadly force. Few are permitted to leave the planet, with many coming under suspicion due to growing concerns about Genestealer Cults. The Omni-Legion has dispatched Vanguard strike teams led by Librarians to hunt Genestealer Cults on numerous occasions, supporting the Tallon Chem-Drakes.

## Chapter Recruitment

Astartes of the Apothecarion and Adepts of the Magos Biologis will journey to the PDF academies in each Hive City on Tallon Primus, collecting young boys who failed to meet Regimental standards. These troubled children will spend days caged while transported to the system's Jungle Death World of Menace. Chapter Apothecaries test every Aspirant’s genetic purity; those deemed unfit are sent to the Mining world of Tallon Quartus. Serfs and Servitors are more than enough to keep the aspirants under control; they are permitted to break an aspirant's limb if they're too belligerent.

#### Trials

* The Culling- Aspirants are left to survive in the jungles of Menace, instructed to journey toward one of the Chapter’s Scout Castra. Countless aspirants have perished on Menace, killed by the fauna, dangerous landscapes, Orks or Chapter Scouts. Until the aspirant reaches an Outpost, they’re treated as hostiles; only the strongest and most intelligent will survive to become Neophytes. The trek will take several days; most Aspirant mortality rates surpass 70%.

* The Tempering - Aspirants are paired and locked in a cell, a single dagger left on the floor. Aspirants are expected to kill each other or be left to rot. They are then released from the cage and immediately face the final trial.

* The Visions - Low-ranked Chapter Librarians induce visions in Aspirants. These visions range from outright terror to promises of power. Librarians scour their souls for desires of glory or power, weaknesses a Daemon can exploit. All who fail are converted into Servitors.

Apothecaries lead Neophytes on Menace to test their physical changes, giving the would-be Astartes the necessary experience in the field before they move on to the Scout Conclaves. Feral Orks are a practical challenge for the developing Neophytes; Apothecaries protect the developing Gene-Seed with a ferocious fury. The years spent on Menace are filled with rigorous physical and psychological training. After receiving the Black Carapace, will Neophytes become Scouts, taking to the stars to hunt foes of the Imperium.

Scouts may serve in the Scout Order for years if the Captain considers them unworthy to elevate to the Support Orders. Scouts will be watched closely by Apothecaries, TechMarines and Librarians; these specialists seek out the potential to join their Orders. Once a Battle-Brother completes his service in the Scout Order, the Progenoid Gland in their neck will be extracted before joining a Support Order. The Vanguard has become another path for Scouts following the Ultima Founding.

## Chapter Gene-Seed

### Genetic Idiosynrasis/Mutation

**The Ossmodula:** Possessing a larger and thicker bone structure. Because of this mutation, the Chapter once had a higher-than-average rejection rate. Secretly reaching a 44% rejection rate by 999.M41. Neophytes suffered from aggressive bone growths that turned them into distorted horrors, and only the Emperor's peace could end their suffering.

Firstborn and Primaris appear nearly identical in height, the Magnificat organ having the same effect as the Chapter's former Ossmodula mutation. The Primaris Marines are considered a gift from the Emperor and salvation from their dying Gene-Seed. The Lord Apothecary became the first Ascended Primaris, experimenting with their remaining Gene-Seed, and modifying it with Primaris materials. Reportedly, the Ossmodula mutations have been cured as of the induction of the Primaris.

## **Notable Members**

* **Chapter Commander Solus** - The current Chapter Commander of the Omni Legion, Solus, has been brutally tested for the last five hundred years. Currently leading half of his Chapter to aid Imperial forces against the Necrons, Solus entrusts the protection of Tallon Primus to Captain Ptolemaios, Canoness Ultima Ashelia, and General Lyle of the Chem-Drakes. In 905.M41, the Omni-Legion, while fighting a growing Ork WAAAGH!, encountered a Hrud migration. Chapter Commander Varro was slain during the ensuing chaos. Under 3rd Captain Solus’s direction, the remaining Chapter forces withdrew from Kelikos II. Solus was promoted to Commander by the remaining Chapter’s leadership during the decades-long rebuilding of their ranks. The ancient armour worn by Solus has seen many modifications, a Terminator plate with speeds that terrifies many. He wields a powerful weapon known as the Omni-Talon, capable of easily tearing through Terminator plate. Solus’s ranged weapon of choice is a gauntlet-mounted storm bolter.

* **Captain Caius** - Captain of the 1st Order, Caius is one of the Ascended. After the Apocryphan Tyranid War, Caius' first task as Captain was to lead a strike force to put down a revolt in one of Tallon Prime's Hive Cities. Caius would discover and slay a Genestealer Broodlord in what turned out to be a festering Genestealer Cult. Caius has been known to battle in a suit of MK.X Gravis armour most frequently, fielding a master-crafted heavy bolt rifle. As the 1st Captain, he’s granted various weapons and armour, including his MK.X Crusade armour and Terminator plate.

* **Captain Vilhelm** - 2nd Captain Vilhelm is second only to Chapter Commander Solus when comparing their void warfare expertise. Vilhelm is staunch in his belief in protecting the Imperium, no matter how much blood is shed. Known among his brothers to be especially vicious with his tactics; thus, he was perfect to lead the 2nd Order. Boarding actions under the command of Vilhelm are known to be incredibly violent, even by the Omni Legion’s standards. Vilhelm became trapped within Imperial Nihilus for nearly a century with his Order, but with his leadership and iron resolve, they reached and passed through the Nachmund Gauntlet. Before passing through the Nachmund Sector, the 2nd Order was assailed by Heretic Astartes of the Night Lords. Fending off the traitors who swore fealty to a Warlord named Decimus, Vilhelm wouldn’t pursue the retreating traitors, prioritizing their return home.

* **Captain Maxima** - During the Apocryphan Tyranid War, the Omni Legion sustained significant losses to the Tyranids, including the 3rd Order and its leadership. As the Order's former 2nd Lieutenant, Maxima was promoted to Captain. Maxima shares his predecessor's interest in testing other races' combat to integrate them into his own. Maxima's artificer armour to battle is an ancient suit gifted millennia ago to the Omni Legion. Upon its breast is the iconography of the Ultramarines, a mark of its origin. Captain Maxima leads a campaign against an amassing Cybork WAAAGH with Fleet Purgius. Before leaving, Captain Gaius gifted him the Xenophade blade, a powerful weapon against the green-skins. It's said that the Orks can will things to happen; the Omni-Legion has fought Orks long enough to see patterns. If they think green is best, the blade might sting harder.

* **Captain Talos** - While his brothers are considered strict, Talos instead displays a more open personality. Some regard him as 'Immortal Talos' due to the dangers he encountered during the Apocryphan Tyranid War. The new Captain defended Hive Stalwart with an unmatched determination, leading his jump-pack brothers across the battlefield to slaughter the Tyranids in close-range combat. Talos once wore a modified suit of MKIII power armour with a jump pack, but after the Apocryphan Tyranid War, much of his armour became damaged beyond repair. Following his recovery, Talos was gifted a new power armour suit. Something was constructed using remnants of his old armour and the MK.X Inceptor. Talos wields a power fist and combi-melta, using hit-and-run attacks that destroy even vehicles.

* **Captain Tiberius** - Inheritor of ancient armour and weapons of Lord Tristan, one of the Chapter's greatest heroes. Tiberius led the 5th Order’s 1st Battleline Demi-Order during the Apocryphan Tyranid War; the 1st Fire-Support Demi-Order supported them throughout their months protecting Hive-Eight. By his words, the walls and cities will crumble to the Chapter. Tiberius’ armour is a heavily modified Terminator pattern, an assault cannon mounted to one arm. Unleashing a torrent of fire as he fights alongside his brothers, his chain fist has claimed many Necrons, tearing through them like paper should they dare approach the Captain.

* **Captain Ptolemaios** - In early M42, the Torchbearer fleet that met with the Omni-Legion carried more than just their new Gene-Seed. A company's worth of Greyshields joined their ranks, accompanied by their Primaris Captain. Ptolemaios was tested by Chapter Commander Solus and the recently interned Lord Gaius. After two days, the trio emerged, Solus declaring the Primaris Marine as Captain of the 6th Order. Tasked with hunting the remnants of Splinter fleet Zurvan, Ptolemaios personally leads the first Conclave to Tallon Primus. The Vanguard Primaris assisted the planet's Arbites without their knowledge, preparing Tallon Primus for the eventual second Tyranid conflict.

* **Lieutenant Gareth** - Gareth is the 1st Lieutenant of the 1st Order, 'Voidwalker' was a title bestowed to Gareth following the void battle at Skar Octus. The Lieutenant led a strike force of Veterans to capture a Battleship—latching and trekking along the hull to capture the vessel's command bridge.

* **Lieutenant Duilius** - The 2nd Order's 1st Lieutenant, sometimes called ‘Vilhelm's Voice.' Vilhelm prefers to spend his time preparing for war, while Duilius tends to have more social duties. He may be more reserved than his Captain and still a fierce warrior. Wielding a power axe and master-crafted bolt pistol. During the Apocryphan Tyranid War, Duilius led the defence of Hive Tallon-Delta. Imperial forces held the Hive for weeks; Lieutenant Duilius and Canoness Preceptor Lysa assumed command after Colonel Helza was killed in battle.

* **Lord Apothecary Vinland** - As the leader of the Apothecarion, Vinland has been tasked with monitoring the Chapter's Gene-Seed and pursuing the education of new Chapter Apothecaries. He has seen many Battle-Brothers' recoveries and Gene-Seed implantation with the Magos Biologis at his side. Vinland was the Chapter's first to take on the Rubicon Primaris to fully understand these new Battle-Brothers' functions, the operation supported by his Apothecarion. Currently, he's still aiding in creating new Primaris Marines, but the state of the Tallon system has seen him preoccupied with higher-than-average interrogations.

* **High Warden Vamos** - Vamos is a skilled warrior who has risen from the ranks of the Chapter's Wardens, his thirst for knowledge possibly surpassing them after the appearance of the Cicatrix Maledictum. Unlike his kin, he has a deep fascination with Xenos tech. Like many Wardens, Vamos's artificer armour is of the Terminator Indomitus pattern. As the Chapter's Reclusiarch, he leads the Wardens in their duties, ensuring they retain the same sense of loyalty to both the Imperium and the Emperor of mankind.

* **Lord Warden Boldwin** - During the Apocryphan Tyranid War, Boldwin was mutilated by a Ravener swarm of Splinter Fleet Zurvan, suffering fatal injuries. Returned to the Grand Providence by his brothers, the Chapter's Wardens and Techmarines began the various life-saving procedures needed for his return to battle readiness. At this point, the Lord Warden was little more than a torso and head; an artificer-crafted suit of Centurion armour was built to host the reawakened Lord Warden.

* **Lord Librarian Gwynn** - On the battlefield, Gwynn will cast great bolts of psychic lightning that will burn the flesh and peel the armour from any foes in his way. As a master of Technomancy, Gwynn has allegedly conversed with the Machine Spirit more directly than even the Chapter's Techmarines.

## Chapter Fleet

The Omni-Legion's Fleet aids multiple Imperial forces across the Segmentum. Ships in the Omni-Legion’s fleet are described as black as the void; their Chapter iconography is barely visible. Pirates and Xeno are common prey; their fleets are torn asunder or usurped by the Astartes that slaughter their crews.

* ***Tyrannis Dominatus* (Courageous-Class Battleship)** - Decades following the integration of the Primaris, the Omni-Legion received a newly constructed Courageous class battleship to add to their battered fleet. Becoming the Chapter’s greatest weapon of war, believed by outsiders to be their Fortress-Monastery, something the Chapter uses to their advantage. The vessel lends itself to the Omni-Legion’s strengths, quickly tearing through enemy fleets and allowing the Astartes to board its crippled prey. Among the ship’s defenders are numerous battle-automata, protectors of the many Magos within the Dominatus. Astartes of each specialization forged chambers to perform their duties away from the Grand Providence and Indomitable Vigilance Battle Barges. The Tyrannis Dominatus aids Battlegroup Mortis against an impending Necron Menace. (10.5km)

* ***Grand Providence* (Battle Barge)** - This ancient vessel has served as the Chapter's Fortress-Monastery for over seven thousand years, laying waste to billions while ferrying terrifying weapons of war. Its history goes as far back as Chapter Commander Garland and the aftermath of the Gulf of Black Shadows, becoming the embodiment of the Omni-Legion’s tactics of analyzing their foe from a distance before shattering them in a single devastating strike. The Chapter’s Librarius and Technicarum remain aboard the Grand Providence after the Indomitable Vigilance joined the fleet. During the Tyrannic battle of Tallon, the ship wouldn’t go unscathed. It remains within the Tallon system to receive repairs, which are expected to take generations before the ship wages war as it once did.  (8km)

* ***Indomitable Vigilance* (Battle Barge**) - Gifted to the Omni-Legion for their assistance in the Charadon Crusade. The Indomitable Vigilance aids in protecting the Tallon system. The Chapter’s Scout Order, Apothecarion, transferred to preserve their Gene-Seed further. The Hall of Ancients and its Wardens joined their ranks, tending to the slumbering Dreadnoughts who await calls to war. (7km)

### Indomitus Crusade Battlegroups

*In the aftermath of the Reclamation of Coele-Myr, the Omni-Legion’s fleet was divided among three Crusade Battlegroups: Mortis, Vindicta, and Purgatus. The Grand Providence, wounded from the first Tyrannic conflict, remains with the Indomitable Vigilance. The Tyrannis Dominatus, tempered from the Reclamation of Coele-Myr, cuts through Mortis’s enemies.*

* **Crusade Force Mortis - Engaged with the forces of Chaos until the awakening of the Xenatar Dynasty**
* **Crusade Force Vindicta - Responding to Chaos invasions in the northern *Apocrypha Sub-Sector***
* **Crusade Force Purgatus - Assisting against WAAAGH!!! Kranefist in the southern *Apocrypha Sub-Sector***

## Chapter Armoury

*The ceaseless war to purge their enemies has brought the Omni-Legion to many worlds to fight alongside numerous allies, with a wide array of weapons many have never seen and may never see again. The Chapter's skilled Techmarines tend their weapons, armour, and vehicles. A Chapter Order can only receive additional weaponry from the Armoury if the Captain convinces the Wardens.*

* **Land Raiders** - The Land Raider is a destructive weapon with numerous variants, but the Land Raider Crusader is the Omni-Legion's most common deployment following its sanctioning. The Ember Sharks introduced the Land Raider Octus to the Omni-Legion during the Sundering of Tallon, sharing its blueprints in exchange for one of the Omni-Legion's Strike Cruisers.

* **Gravitic Battle Tanks** - Belisarius Cawl's new weaponry was introduced alongside the Primaris Space Marines. These new vehicles terrorize every enemy that dares cross them, weaponry cutting them down and melting holes through Daemon Engines.

* **Battle Tanks** - The Predator Annihilator is the Battle Tank of choice for the Omni-Legion due to its destructive Lascannons. Hunting enemy armour like a true predator favour moving quickly around the battlefield and flanking artillery. Other variants are available to the Omni-Legion though rarely are Predators utilized for anything but anti-armour assaults.

* **Transport Vehicles** - The Rhino remains the most versatile vehicle in any Space Marine Armoury, capable of transporting infantry as they are or waging destruction as the mighty Predator. Battle Brothers are expected to learn the basics of piloting a Rhino. Following behind Land Raiders or Vindicators to deliver Battle Brothers to war, remaining on standby for possible withdrawals or fire support.

* **Light Attack Vehicles** - Bikes and Land Speeders comprise the bulk of the 4th and 6th Order's armour support with mobility and speed. The Tyrannis Dominatus maintains a surplus of light attack vehicles should the remaining Orders request their use. The Invictor Tactical Warsuit is considered to expand to all Orders rather than only the Vanguard.

## Relic Vehicles

* **Cerberus Heavy Tank Destroyer** - One of the weapons that the Omni-Legion keeps in stasis, unwilling to risk losing it. This vehicle was uncommon even during the Horus Heresy, treated with great reverence.

* **Mastodon** - This singular war machine rests deep in the Grand Providence with many other ancient relics, but the Mastodon has seen battle unlike many. The 5th Order and its experience in grinding warfare fit a Mastodon's design, even working as a means to transport Lord Tristan for the last few millennia. Records of its discovery appear lost.

* **Sicaran Battle Tank** - Another venerable machine kept in stasis for all time, the Sicaran Battle Tank is watched over by Skitarii Ruststalkers, provided by Roitheta's Tech-Priests. Time only flows for the Battle Tank if the Chapter's Wardens seek to examine it.

* **Land Raider Achilles** - Remarkably, the Omni-Legion has attained three of these Relic Machines and rewarded them for repelling the appearance of a small but deadly Xenos race. The Omni-Legion sent its Battle Orders to aid the Imperial Navy with their fleets; a year later, the race would be categorized as Extinct. The Achilles rarely leaves stasis containment unless ordered by the Chapter Commander and the Lord Warden.

## Chapter Relics

* **Tome of Omicron** - An ancient text entrusted to the Lord Librarian. Its pages can only be read by a Psyker who knows of the book's contents, thus ensuring its secrets from the Mechanicus, who could view such a tome as heretical. The Chapter’s technomancy research has led them to link the Machine Spirit to the Emperor’s psychic presence.

## Chapter Appearance

### Chapter Colours

The Omni-Legion armour primarily has a silver colour scheme with red upon the pauldrons, knees and the plating covering the stabilizing jets of their backpacks. The Omni-Legion's Orders do not utilize Company trim colours on their pauldron; instead, Orders are typically marked on the Battle Brother's left knee while their squad number is on their right pauldron. However, the 1st and 6th Orders are the exception to these.
