Delhumide is the name of the central tharch or region of Thay and its local capital.
2300 years ago, when Thay had been a Mulhorandi colony, Delhumide was one of its greatest cities and bastions of power. When the Red Wizards rebelled, they destroyed the town, using the darkest sort of sorcery to accomplish their task. In 1375 DR, the ground where the city's ruins still stood was still unclean. Demons walked there and a man could suffer from madness or leprosy just by venturing there. Shattered battlemets and toppled towers could be seen though many of the buildings remained essentially intact.
