Editing Nobledark Imperium Forces of Chaos (section)

===The Twiceborn===
Unusual for the Dark Mechanicus, this sect has its roots in the Biologis and (very distantly) in the transhuman ideals of Horus Lupercal. Their beliefs and goals are simple; they think that the Materium is doomed to eventually be submerged in the Warp, and that Mankind's only hope of survival is to somehow become warp entities. 

To this end, they seek out... lots of things. Daemon princes, and lore regarding them; how they're made, and how they sustain themselves. Powerful psykers. Mutants and Chaos Spawn. The Legion of the Damned. Psychneuein. Mandrakes. Navigators. Anything that might give them insight on how the flesh might be transformed by the warp, and survive. 
And, of course, any knowledge of the Men of Gold. (They'd kidnap Oscar if they could. But they know they can't.) 

Daemon Princedom is inadequate for their goals; they need a method that is not dependant on the favor of the gods, that can be reproduced at will. They haven't managed it. What they have managed are the twiceborn. 

The twiceborn (from which the sect takes its name) are liminal existences, half of the materium and half of the warp. They can slip through the boundaries between the two nearly at will, and even- with great difficulty- remain suspended on the border, half in both. They are not daemons. They stay dead when killed. Their existence is one of perpetual flight, constantly switching between realms to avoid all the things that want to kill them in both. 

To the Twiceborn Sect, these beings are part saint, part vivisection subject, and part commodity; the focus of their research and primary trade good. They sell these things to other warbands from their labs in the Eye, to support their roving fleets, dark mirrors of the Explorators, perpetually searching for knowledge and more test subjects.
