ahn's a mercenary. Quick with a bow and deadly with a blade. He grew up in the streets of Waterdeep, so picked up more of the urban skills, like thievery and dungeoneering.
While he tries to portray the cold and calculating exterior most men with his skillsets project, deep down, he's a good guy. He has a soft spot for the weak or innocent, and will go out of his way to help someone down on their luck, especially if no one's looking. In fact, now that Zahn thinks about it...he's a pretty shitty merc. Maybe a life of adventure is more his calling
