I have psyker that I intend to have collecting the skulls of his enemies to turn into a horde of servoskulls. The intention is to taunt khorne by "keeping the skulls for himself"
Bad ass, I like it!
My game is set in a former Imperial world that was sucked into the Screaming Vortex and has since lost a lot of its technology and is cut-off from the outside world and hence has turned a fuedal type land.
For this reason I have no CSM but the players seemed to have used their imaginations well to come up with some cool ideas.
We have an apostate who has no memory of how he arrived on the planet saved brief glimpses of violent memory. He believes that he is destined to bring the Gods back to this forsaken realm and tells himself that he is doing good deeds by following the will of the Gods (deep down he knows this isn't true but he knows the Gods are pleased with his work and that's all he needs to know). He has a variety of strange minions including a psyker who lost his bones when his soul was bonded to a sea god. He is now literally a very blubbery minion indeed.
Another character is a rogue psyker who suffered at the hands of an abusive husband until her powers manifested and she killed him. Other men sought to use her powers for their own ends but all suffered the same fate. She has since vowed that she will never be used again and will in fact use men for her own ends, keeping an obediant husband with her at all times as a minion. As each one dies loyally to serve her she simply replaces her "husband" with another.
The other dude hasn't made his yet but I am pretty sure he will be a renegade "kill for Khorne" type.
All in all a nice balanced group with some interesting characters, I am looking forward to the game.
