Uzzi was Mordecai's older brother and died during the eleventh-floor progression created by Odette's broken deal.
Uzzi was the older brother whom Mordecai admired and followed. Their bond reminded Odette of her younger cousin Pieter and helped motivate her to become Mordecai's manager.
Odette arranged for Huanxin to rig the game, then reversed course and trapped Huanxin's goddess Dodola for Chaco to kill. Mordecai reached the next floor, but Uzzi died in the operation's fallout.
His death left Mordecai grieving through centuries of indentureship and became one of the central harms Odette attributes to her own obsession with completing her contract.
