A prison of sorts well below the sands beneath a flying city. Former humanoids are screaming and singing and weeping in arcane cells that capture them. The mere sight of them could cause mania or insanity. Floating jellyfish like creatures – Flumphs, a good-natured sociable sort of aberration that dedicates themselves to defending the word from cosmic horrors – act as the prison’s guards or wardens. Khafre said he recalls this prison – that it was a prison for abominations that should never have been, and that the Oracles predicted it would one day fall. This place seems dangerous.
