I actually have two ideas Epic, and I will go with whichever you feel works better for the RP. The first is a rigid inquisitor of Stendarr similar to my character Isidor in A Sinking Feeling. Very strict, very religious, almost completely uncompromising in fulfilling his duty to Stendarr, kills without mercy or remorse if his code deems it necessary. The second is a female vampire and a complete sociopath. She's been killing for hundreds of years and is an extreme hedonist and nihilist. So much so that she's how to distinguish pleasure and pain and kills her victims with unbearable ecstasy.
Huh...did I just describe Samara and Morinth to the letter? I think I did...
