In a chasm whose ceiling is higher than any mountain stands the abandoned city of Arak Yor. Up and down the enormous walls, multiple layers of dwellings are carved into the stone. This ancient but clearly humanoid construction surrounds a central community of utterly alien make, with towering spires and pod-shaped masses grown or melted directly from the rock. Those who have had the misfortune to meet the illithid servants of the daelkyr recognize these central features as of mind flayer construction, yet even those fearsome creatures abandoned the city centuries ago. Legend says that something is imprisoned at the peak of the city’s central spire that is neither demon nor daelkyr, and whose presence drove even the mind flayers to madness. Today the city is inhabited only by golems and other constructs of ancient design, mindless caretakers of a forgotten dwelling.
