Which never got finished and which you never shared with me... 
If you want I'll tell you...
Still interested in signing up, but I wouldn't mind a bit more background info. Had a few very off-the-wall ideas, unusually I'm thinking of playing a non-Imperial for this one. Problem is, not sure if these are too distinctive or powerful to be usable, or if they'd have a good reason to be here. Eldar outcast/ranger working to thwart/bring about a Farseer's vision, a chaos magus who made a deal with a daemon as a young man without realising the consequences and survives by continually making new deals (he's ended up pretty damn powerful) or, the most out there idea, a banished (and ritually blinded) Word Bearer on a pilgrimage of sorts. Mostly he'd act behind the scenes through servants and intermediaries (possibly including our magus), as it's hard to hide when you're a chaos marine.
