The Abyssal Depths is a sprawling labyrinth of dark, damp tunnels that seem to stretch infinitely beneath the surface. Here, crawling shadows slither along the walls and echoes of monstrous growls resonate through the air. It is said that this is the fortress of the Shadowfell's demons and other vile beings, who gather in sinister councils to plot their insidious attacks on the world above.
