An older successful mercenary in the Chapter of Phantoms, Olsan helped Karthos start a new life by getting him employed within his Mercenary group. Olsan served as Karthos's mentor for many years, and helped orchestrate Karthos's "employment" on the expedition to help him escape the Chapter of Phantoms after failing to assassinate Camellia.

Olsan Ravaric is the member of the Chapter of Phantoms, and found Karthos as a young man whose life was ruined by the drow. Seeing something special in the young man, Olsan took Karthos under his wing and mentored him, teaching him the art of combat, monster hunting, and how to cover your own tracks. Despite his grim occupation, Olsan has a very warm personality and you can always find him by checking the local taverns for his roaring laugh.
