Hello, hello!  I played a bit here a while ago, but basically I am new, and this guy certainly is.  His name is Nick Ryves and he's a character from The Demon's Lexicon by Sara Rees Brennan.  I'm trying to get his voice, so please forgive if I struggle at first--I'll try to keep him as IC as possible and still have him actually speak words to other people.  Nick happens to be a demon and he can't lie, but he has somehow mastered the art of sarcasm.
