The Halls of Ghuldesh (Patreon)

Originally a small fortification on a rocky outcrop, the Halls of Ghuldesh were magically formed out of the rock beneath the fortification by an order of druids. The old fortifications are but a few stones atop the hill now, but the druids’ work and standing stones remain.
