Black-Rock Shafts

The echoes of pickaxes still ring through the claustrophobic dark.

8 roomsminemedium

A decommissioned cobalt mine consisting of cramped, timber-propped tunnels and damp excavation chambers. The air is stale and heavy with the scent of wet stone and ancient decay.

The smell of damp earth and metallic cobalt fills the nose. Periodic tremors cause dust to fall from the ceiling, and the only light comes from rare, flickering patches of phosphorescent lichen.

☠ Threat

Vorgath the Forsaken, an undead mine overseer, stalks the lower depths. He has been warped by the earth cult's magic into a hulking ghast-like entity that commands the local vermin and the spirits of his dead crew. His presence causes the very walls to weep a black, oily substance that slickens the floors and poisons the water.

History

Originally a prosperous source of rare minerals for the nearby duchy, the Black-Rock Shafts were abandoned thirty years ago. Miners broke through a thin wall into a forgotten burial site of a primordial earth cult, unleashing a necrotic miasma. Most workers fled, but those trapped below were transformed into restless shadows of their former selves.
