Im not a vampire, Ihave killed an innocent in
the female gang quest (for some reason the last girl was "innocent") because i got the message from the dark brotherhood. I havent joined the dark brotherhood however. Generally i have been a good character throughout. Also i have tried getting rid of all my stolen items in my inventory too and that didnt work.

I am level 30 something now, middle 30's i think. Hope that helps you help me lol! Thanx
