The Drowned Enclave

Echoes of ancient sorcery ripple through the murky, crushing depths.

28 roomssunken netherese cityhard

A shattered fragment of a Netherese sky-city that plummeted into the ocean centuries ago, now partially submerged in a deep underwater trench. The ruins are bioluminescent, lit by magical fungus and the psychic aura of its current master.

The air is cold and smells of brine and ozone. Walls are slick with glowing turquoise moss that pulses with a heartbeat-like rhythm. Occasional muffled screams of trapped spirits echo through the waterlogged pipes.

☠ Threat

Xhaal, an Aboleth of immense age, wields a fragment of the Dreamstone to manipulate the minds of those on the surface. It seeks to reconstruct the stone to pull the rest of the sunken city into its dream-realm. Its influence is felt as a rhythmic, psychic thrumming that causes headaches and vivid hallucinations for any non-aberrations who linger too long.

History

When the city of Thultanthar fell, this specific research sector plunged into a coastal shelf. Over the centuries, the magic keeping the water out failed, flooding the lower levels. An ancient aboleth named Xhaal discovered the ruins and used a fragment of the legendary Dreamstone to turn the site into its personal nightmare cathedral, warping the local wildlife and surviving Netherese spirits into aberrations.
