Origins: The Guardian Host was created during the Ultima Founding at the behest of an unknown Inquisitor's petition to the High Lords of Terra and Gulliman himself. Only the inquisitor in question, Gulliman, and The High Lords knows their true purpose, but as far as the Imperium at wide is concerned, they are tasked with the defense of the world Gaia and the protection of its mysterious Xenos Relic, the Bastion. After the opening of the maledictum and the subsequent division of imperial space, it was clear that the sector would need additional support and defense in the form of a chapter of Astartes to protect the system from invaders.
The Bastion: Directly beneath the center of the Last City is an ancient and mysterious machine known as the The Bastion, a great maze of living metal. The mysterious structure appears to be of ancient Eldar construction as the interior is dotted with soul stone that appear to be inert. The Librarius and Tech Marines of Guardian Host were task by the inquisitor to study and understand this ancient relic that they believe dates from the fall of the Eldar empire. It is uncertain exactly how the The Bastion came to be on Gaia although it is believed that the Eldar put it there when the humans were still in a tribal state. Any humans that come into contact with the device gain the unique ability to control and generate wraithbone structures from their own bodies, but it comes at a significant cost as those who have used this power have gone into a comatose state as their bodies are slowly transformed into inert wraithbone statues. As the side effects have proven fatal to the people of Gaia, the inquisition and the Astartes of the Guardian Host have quarantined the device pending further investigation and study, the Astartes becoming its lone security as they are wholly unaffected by the device's properties.
Homeworld: The Guardian Corps draw their recruits from and make their home in a small system on the edge of the Segmentum Obscurus, on the planet Gaia. It is a dangerous, wilderness planet with conditions not unlike Holy Terra before the Rise of humanity; Deadly beasts, poisonous flora, and unrelenting weather have made the surface of the world nigh uninhabitable, save for a single bastion known as The Last City. Although some shun the protection of the City and instead reside as clans within the old ruins of Gaia, it is within this city’s walls that most citizens of Gaia go about their day to day lives, under the looming gaze of The Tower, The Guardian Host’s Fortress-Monastery. Upon reaching the Age of Ascension, Males of the planet form into hunting parties where they must survive in the most dangerous parts of Gaia and bring down one of the craven beasts prowling the wastes. After they return to The Last City with proof of their deeds, those that return Successful undergo the Infusion, a Ritual where they leave their pasts behind them, conditioned literally to forget the people they were so they can better serve the Emperor; any who survive begin their transformation into the ranks of the Adeptus Astartes of the Guardian Host.
Gaia: Deep within the region now known as Imperium Nihilus resides a small system; a Star with three planets trapped in its orbit, Gaia, Nessus, and Ionis. Nessus is naught but and cold barren rock, long since stripped of its natural resources by a still silent threat believed to be stirring beneath its surface, it also has a single moon. Ionis is covered in vast cliffs, dangerous creatures, and dense vegetation, it contains an Imperial research outpost dedicated to the study of its strangely sentient Flora and Fauna. Gaia is a vast wilderness planet wrought with dangerous lifeforms, at its center is the great Imperial city known as The Last City. Encompassed on all sides by great walls, the city serves as the only safe haven for the planets citizens, a once nomadic people who barely survived the harsh conditions of the planet. Located in the center of the city is The Tower, Fortress-Monastery of the Guardian Host. Within its heavily fortified walls the Risen are trained to become full Astartes in the Crucible, a Vast Training arena when the Risen are pitted against full Adeptus Astartes in training designed to push them to their very limits and prepare them for their duties. At the Apex of the Tower lies the command center where the Chapter Master and his advisors, the Captains of the Clans, coordinate the Chapter and its engagements across the Galaxy. Gaia also has two moons, Gaia Minoris and Gaia Secondus. Both are little more than barren rocks trapped within Gaia's orbit, although Gaia Minoris has a long abandoned structure upon its surface that seems to be linked to The Bastion.
Combat Doctrine: Like their trials of ascension, the Guardian Host fight in groups of soldiers known as Fireteams, usually made up of four members and one Fireteam leader but typically fluctuating between three and eight astartes. These Fireteams are bonded for life, fighting, training, and dying together as a single unit. Should a single member of a Fireteam survive his teammates, he becomes a Lone Guardian, taking on an oath of vengeance to atone for the loss of his fallen brothers. Should he return from this oath successfully he goes on to be the leader of a new Fireteam, selecting new recruits from among the Risen, those who have undergone the Infusion and completed their training as neophytes.
The Infusion and Individuality: Like most Chapters, the Guardian Host has a ritualistic approach to their transformation into Astartes. The Infusion as it is called is the process that they use to transform their recruits. Though shrouded in mysterious rituals, the Astartes who survive this process lose all memory of their past lives, instead dedicating their whole selves to their duty to the Emperor and the Imperium. That said, only their memory is affected, unlike other Astartes, Guardians retain most of their personality from their time as mere mortals and it shapes who they are and how they fight. Guardians are in fact encouraged to express their individuality, given the freedom to decorate their Sacred Power Armour in whatever way they see fit, although most Fireteams prefer to have some semblance of cohesion. The only required iconography of the Guardian Host is their left Pauldron, Vambrace, and Gauntlet must bare the black steel color of the chapter and the Chapter's badge must be emblazoned upon the Pauldron.
Organization: The Guardian Host does not use the traditional numbered company layout of the Codex Astartes, instead each company is a named Clan of Astartes, similar to the clan structure of the planet before the arrival of the Chapter. These Clans, along with the Risen, make up the fighting companies of the Chapter. When they are called upon to perform their duties to the Imperium, a singular Master is chosen from one of the Clans and he hand picks all of the Fireteams for the engagement.
Each Clan, though fulfilling a different purpose, has the same structure; a Command Host, made up of the Veterans of the Clan, 10 Battleline Fireteams, 5 Fire Support Fireteams, and 5 Close Support Fireteams. The Risen, being the reserve company, has at any one time 5-9 Battleline Fireteams, these teams train the neophytes of the Guardian Host in the ways of the Adeptus Astartes.
Nightstalkers: This Clan focuses primarily on Covert operations, they possess the largest concentration of Vanguard Adeptus.
Arcstriders: Astartes from this clan are known for their long range fire support and pinpoint accuracy.
Sunbreakers: The Sunbreakers specialize in rapid and orbital strike combat.
Sentinels: The Sentinels are the clan tasked with the continued protection of The Last City and all citizens of Gaia.
Dawnblades: Members of the Dawnbladed specialize in close assault tactics, many would consider them rash and headstrong but their discipline allows them to bring switch vengeance upon the enemies of the Imperium.
Stormcallers: Known for their ferocity, the Stormcallers clan are dangerous hunters who stalk their prey with deadly precision.
Voidwalkers: The Voidwalkers specialize in combat in the vacuum of space, whether it be cracking into derelict space hulks or mag-linking to the outside of enemies ships for breaching maneuvers.
The Scions: Home to the Veterans of the Guardian Host, The Scions have access to the best and most powerful equipment of the entire chapter.
Geneseed: The Guardian Host owe their genetic heritage to the Sons of Dorn themselves, the Imperial Fists. It is widely believed this is where the chapter gets its proclivity for siege warfare and fortifications.
Battlecry: “We fight. We die. We live again!”
The Red War [025.m42]
Early in the history of the chapter, the ork warboss Brakkus Ironshredda lead a sizable WAAAGH against the defenders of Nessus. They were only stopped by the bravery of librarian Eris Morn and his fireteams, plunging into the heart of the WAAAGH and killing Ironshredda sending the surrounding orks into blind panic which ended up killing many of them. The Guardian Host suffered sizable losses however and nearly half of the Arcstriders clan was killed in action.
The Taken King [029.m42]
Warp Incursions around the system became a growing threat to Gaia, in response Master Zavala dispatched Cayde-6 and his fireteams to investigate the supposed source of the incursion, Gaia Secondus. Upon their arrival they found a Tzeentchian cult attempting to summon a greater daemon known as the Taken King into real space. Through their bravery, the cultists were defeated and the daemon banished back to the warp, although at the cost of almost an entire fireteam. Uldren was the lone survivor of his fireteam, vowing an oath of vengeance upon the Tzeentchian daemon that killed his brothers.
Return of the Infinite Mind [035.m42]
A decade after the Red War, the Necron Overlord Panoptes the Infinite Mind, traveled to Nessus after a fireteam on the planet accidentally activated an ancient Necron structure. Within the structure was hundreds of necron Canoptek weapons that the Overlord had come to reclaim. Thankfully Lord Shaxx and Eris Morns' fireteams were able to destroy the facility and repel the necron raiders before they could recover the dangerous weapons.
The Forsaken Betrayer [039.m42]
The Lone Guardian Uldren travelled to Nessus on a tip that the Tzeentchian cult who killed his fireteam may be attempting to sway the planet to their cause. After weeks of no contact, a Fireteam was sent to investigate the planet lead by Cayde-6. Upon their arrival, the Fireteam was immediately set upon by cultists and daemons. Once they fought their way through the hordes of chaos, they arrived at their makeshift base to find Uldren leading the cult, the Fireteam was killed by the cultists, Uldren assassinating Cayde himself. Captain Ikora Ray dispatched the entirety of the Voidwalkers to crush the cult once and for all and bring the traitor Uldren to justice. After the incident all records of Uldren were sealed and his name expunged from the chapter's records.
