Echoes of the Obsidian Maw
The darkness here does not just blind; it hungers for the light of the soul.
A sprawling subterranean network of limestone tunnels and obsidian-slick chambers that descends deep into the Underdark's forgotten veins. It is a place where reality thins and the elemental power of earth feels oppressive and alive.
The air is heavy with the scent of ozone and wet flint, filled with the constant, low-frequency vibration of shifting tectonic plates. Lighting is non-existent except for the occasional pulse of necrotic purple light from crystalline formations.
☠ Threat
The Void-Stained Progenitor, a gargantuan elemental horror fused with the cavern walls, manipulates gravity and stone. Its influence causes stone to bleed, shadows to bite, and reality to fracture as it slowly digests the world above. It seeks to pull the entire surface realm into the crushing embrace of the planet's core.
History
Long ago, a cabal of Lithomancers attempted to petrify a dying god of the void to harness its essence for immortality. They failed, and the cave systems they inhabited were twisted by the god's final, silent scream. Now, the stone itself is malicious and ancient, fueled by a lingering, divine resentment that refuses to die.
