The Thief-Lord was a powerful man among the gangs on the streets of Deadman's District in Hajra. He commanded a gang called the Lightnings. After the death of his mother the Thief-Lord took Briar Moss, who had been known as Roach in that time, in and taught him the ways of a thief. The Thief-Lord also gave Briar his street name, Roach. He doesn't appear in any of the novels but has only been mentioned various times by Briar, when he was talking about his childhood in Sotat.
