Sector Phatmos.
A sector of space occupied by the Imperium of Man. Its worlds lie in the galactic Eastern Fringe, close to the edge of the territory of the insidious Tau Empire, and is under near constant attack by xeno's and heretics alike as is most of the Imperium by and large.
This collection of worlds is protected by Imperial Guard regiments drawn up from there worlds. The men and women of these regiments are led by the Lord General Militant, Theodora Indigo.
The sector had its own Battlefleet, Battlefleet Phatmos. These ships, of the Imperial Navy, the Adeptus Mechanicus, and Space Marine vessels were collectively led by the eccentric but effective Lord Admiral Yi Han.
In addition, the Sector hosted a convent of the Sisters of Battle; the Order of Defiant Repentance, led by Canoness Indominus. Protected places sacred to the Ecclesiarchy, as much the faithful of the Emperor from those who would dare do harm.
In turn it was home to nine Space Marine chapters, collectively known as the Fellowship of Repentance. For these Space Marines are descended from those of the Traitor Legions who stood with the Emperor of Mankind during the Horus Heresy, against their Fallen Primarchs. The Chapter Masters of these Chapters collectively referred to themselves as the Prodigal Sons.
The sector is also home to a number of Forge Worlds. Planets of the Tech Priests, which produce the war machines and weapons of the Imperium of Man, as well as a number of the Adeptus Mechanicus's own Skitarii, cybernetically enhanced warriors that served the Tech Priests. The Legio Titanica, towering war machines, that require hundreds to crew them, but they can decimate entire armies. As well as providing Knights, smaller scale Titans that require only a single pilot, to the Knight Houses of the sector. The Legio Cybernetica, the Tech Preists purely robotic forces. Led by the ancient Fabricator General, Cynthia Iron-Skin, the Adeptus Mechanicus explores for ancient technology from the Dark Age of Technology, and protect their holdings, as well as those of the Imperium itself from external threats.
Each of these forces is dedicated to protecting Sector Phatmos from the alien, the mutant, and the heretic alike.
Among these threats are the Tau Empire. The Sector's closest neighbor, as since the Damocles Crusade, the Empire has made attempts to expand into the Sector. Each time, repelled by the forces of the Sector on whatever planet the Tau Sept of S-Sen'tai sought to conquer for their Greater Good.
The Eldar of Craftworld H'sar, though they provided aid to the Sector from time to time. They were still mistrusted, both for their underhanded methods, disregard for Human life, but most of all the fact that they were aliens. Not helped by the raids perpetrated by their debased kin, the Dark Elves.
The Dark Elder of the Cabal of the Wet Blades, made frequent raids to the rural worlds of Sector Phatmos, kidnapping Humans to serve whatever debased desires of their new masters in the Dark City of Commorragh.
The Sector is also periodically under attack by Ork Waaaghs!, and Ork Freebooterz. The war like green skins pillaging and raiding worlds. Thankfully, only a relatively small number of worlds were conquered altogether, while others still must deal with the infestation of Orkish spores, and Feral Orks.
Then there are the Necrons of the Osirian Dynasty, ancient and implacable robots, based from there Tomb World of Geb. They commanded the other Tomb Worlds in the sector to awake, and strike at random across the myriad worlds of the sector.
Even this Sector has not been sparred of the horrors of the extra-galactic Tyranids.
The sector also faces raids from Chaos Space Marines. Particularly from war bands of the original Traitor Legions, there goals mainly being to cause havoc, and badger there Loyalist kin into succumbing to the Ruinous Powers. Only a small handful of the Prodigal Sons Chapters have fallen, though the Prodigal Sons made short work of their fallen brothers.
Last, but definitely least. Was a relatively obscure race on the galactic stage, known as the Dregs by Mankind, but referred to themselves as the Q'yr-Vashad, were enslaved long ago on their homeworld, known to humanity as Dreg's Nest. Known for their rapid breeding and subservient behavior. They made for ideal slaves for the Humans of the Phatmos Sector. However, over the millennia since the Emperor integrated the space that would become Phatmos. A number of Dreg's have openly rebelled against their Human masters. During the 41st Millennia, many Dreg Cohorts, groupings of independent Dregs, willingly joined with the Tau Empire, submitted themselves to Chaos when such offers were made, or allowed themselves to be assimilated by the Tyranids. Though many went their own ways out of the Sector, mistrusting other aliens as much as there former masters. There is at least one independent realm of the Dreg's, known as the Q'yr-Vashad Freeholds. The ultimate goal of these renegades is to liberate there people, and their ancestral homeworld no matter the cost. Despite their immense disadvantage on the greater galactic stage.
For in the grim darkness of the far future... there is only war.
