Ahmaergo
Ahmaergo is a dwarf nobleman, former leader of the Iron Ring and current officer of the Xanathar Guild. When the Xanathar Guild took over the city of Skullport, the Xanathar assigned Ahmaergo the sheriff.
TGA met Ahmaergo in the Black Tankard, a tavern in Lower Skullport, during the New Flame's attack on Skull Island. Ahmaergo seemed unbothered by the attack, declaring that he was safe in "his city".
