East Ancient Castle

In northwest Birchland, an ancient castle sits a few hundred feet from the edge of the Colorless Hills. Explorers looted the castle long ago, and it has been left mostly undisturbed for some time. The two-storeyed castle is trapezoid shaped with a large hall in the center, and halls and rooms are roughly symmetrical on either side of the central halls.
During 2023-09-30 East Ancient Castle a group of adventurers searched the castle and ridded it of a large following of Cultists/Claws of the Destroyer led by Evandra. The cultists summoned a huge group of devils led by Authizyr, however, which now reside in the castle.
