Traversing this canyon of cadavers and monstrous remains is laborious enough, but it is the churning and digging below the surface that causes you to hate this awful place. What sort of monstrosity could span the entirety of this ocean of bones? Your answer presents itself as you come across a great pit in the ravine. It is swallowing the bones and scraps of rotten meat like a whirlpool. When you reach the base of the tunnel and realize its true purpose, a shudder courses through you. It was made by an enormous creature: the thing that dwells below the sea of bones.
