The Federacy 017M42

The Federacy is a seccessionist group of Human Worlds who left the Imperium many decades ago after the arrival from the warp of Admiral Haskell, a great leader from the time of the Horus Heresy who was tricked by Horus into supporting him. When Haskell found out, he fled to the warp only to return ten thousand years later. After various secessionist wars the Federacy established itself as an ally to the Tau Empire, promoting the original Imperial Truth of science and innovation, turning its back on all forms of religion.

Now the Federacy finds itself embattled with frequent chaos incursions from the rift. During the upheaval several federal planets and outposts were lost, but it has maintained contact with the bulk of the Tau Empire. However, the Federacy now finds itself on the Front line against the Imperium's fight to reconnect to the Dark Imperium and must face threats on three sides.
