The Brine-Drenched Fane
The depth calls to the mind before it claims the body.
A submerged network of sea-caves and carved obsidian halls that pulsates with a rhythmic, alien thrum. The walls are slick with a psychotropic mucus that glows with a faint, sickly violet hue.
The air smells of ozone and rotting kelp, while the walls hum with a low-frequency vibration that causes headaches. Bioluminescent barnacles provide dim, flickering light in shades of blue and green.
☠ Threat
The primary threat is the residual psychic aura of Ol-Gath. It manifests as auditory hallucinations and compels the weak-willed to walk directly into the crushing depths. Its current terrestrial guardian is a Sea Spawn Noble, a mutated creature that acts as the Aboleth's primary proxy and mouthpiece. Those who linger too long risk permanent mental scarring or being physically transformed into the very monsters they came to hunt.
History
Long ago, Ol-Gath the Aboleth carved this sanctuary to escape a celestial war that scorched the skies. It harvested the local coastal tribes, transforming them into mindless, aquatic servants to guard its eternal slumber. Though the master sleeps in the deepest trench, the lair remains a vibrant, pulsing organ of psychic energy. Its influence has recently reached the surface, causing the tides to turn black and local fishermen to vanish into the surf.
