Slag is the leader of the Forged and is originally from outside the Commonwealth. When first accepting recruits, it was a slow process, as many of the recruits died early in the trials. At some point, he engaged in conflict with the Gunners and killed many notable members, or convinced them to pass the trials. Eventually, negotiations were reached, ending the conflict, as well as inspiring more people to join, and prompting the Forged to remain in the region. By the time the Sole Survivor reaches the Ironworks, he has a strong, well-equipped raider army. However, scrap iron shipments had stopped, limiting the effectiveness of the facility, prompting him to send Bedlam to Dunwich Borers to obtain more.
