Hm, well, I honestly had some doubts of whether I'd be able to join in this epic 40k tale (since I'm juggling school and work practice along with some writing, as well as a couple other roleplaying threads) but I have decided to join in this, and think that my character page will come in either tomorrow or the day after tomorrow. 

The character concept comes somewhere in the middle of my two earlier ideas: a noble boy with plans for diplomacy, with latent psychic abilities - not enough to sling warp-blasts around or anything that dramatic, - but good at telling others' feelings (helps in diplomacy, but nothing beyond what a highly empathetic non-Psyker would be capable of) but gets more vulnerable to nasty Warp-phenomena in exchange. 
The ability to vaguely sense emotions in others would also explain his empathy: feeling some of the joys and pains of others will have an effect on a person, for good or ill... or both. 
That sound like an okay character concept?
