Pits of Pandemonium
Near the Hinterfast lies the legendary Pits of Pandemonium. The region is small valley with several great maws in the earth. These caves roar with a howling wind that emerges from some unknown underground source.
The Pits are infamous for spawning foul creatures and evil humanoids. Efforts in the past to collapse the tunnels has met with middling success, as new caves open within a generation.
