Ott was a renegade of the Ironmaster clan. He first worked as pirate but later was offered a place in the Xanathar's Thieves' Guild. He quickly accepted, liking the prospect of more power and a less dangerous life.
The reorganization of the guild (and the secret change of the guild master) gave him more freedom in his thieving operations, which Ott greatly enjoyed. He became good friends with Ahmaergo and the two dwarves often drank together.
