Kitar, is an assassin from the same Order as Anwun. Assassin she might be, but her techniques are quite different. Her arsenal includes potions and powders and extracts of exotic herbs ? for most part they aid her mates in the order, but she has used the same effectively in completing certain high profile missions.
