Kaithias, Drow Assassin
The silent drow from the realm of Faerun has a tendency for theft, and a hatred towards any who have wronged him. His knowledge, however, has helped the party on numerous occasions, gaining them access to a Thieves' Guild within Charing and helping provide for meals in the wild. He silently observes interactions between the party members and while he doesn't exactly join in the festivities, he does seem to relax around them, moreso than with others.
His recent interactions with lycanthropes left him damaged and isolated in a foggy plane within a mirror.
