I suspect that I'll lash together some sort of accursed Guardsman deserter. He's been exposed and/or tainted by contact with the Arch Enemy. I'm thinking that he's slowly being consumed by his desires (mutating), which imo will mean that he's heavily aspected to Slaanesh. My reasoning for this is on account of his horridly deviant ways (be it food, things of a sexual nature, drugs and of course pain), and the fact that he just seems to be enjoying himself a wee bit too much ^^. He'll definitely be a close-quarters combatant, which means blades and pointy objects. Perhaps even with a growing psychic gift, most likely powers that'll allow him to enthrall and/or pacify his opponents, allowing for their slow and flavourful (and painful!) demise
Caeron, Champion of Slaanesh, Disciple of The Deviant One, and Slave of The Thousand Arts of Pain. Yeah. I think that'll be my guy
