Thief once had a name, but he lost it when he was caught stealing from another member of the Great River Tribe. His brother, chief Olbar the Mountain Tall, took it away from him.
With no honor and cast out of his place among the hunters, Thief is forced to scrape a living on the outskirts of the village. He spends much of his time fantasizing about getting revenge on his brother and regaining his name and status. The crafty Bone Woman knows this and uses it to her advantage, manipulating Thief through his greed and bitterness, making him her pawn.
