Screetown was the ruins of the section of Undertown near New Sanctaphrax. It was created when diseased chunks of the New Sanctaphrax rock fell and crushed that portion of Undertown, which included the Boom-Docks and the Western Quays. Screetown was infested with Rubble Ghouls and was greatly feared by most inhabitants of the Edge. The only civilized inhabitants of the ruins were the Ghosts of Screetown.
