Hollowvein Mine

The rhythm of the deep is broken by the scent of ozone and old blood.

4 roomsminemedium

A derelict iron mine where the walls weep rust-colored water. Now inhabited by a paranoid kobold tribe, its depths hold jagged crystals and deadly pitfalls.

Cool, damp air carries the scent of wet soot and copper. Occasional tremors cause dust to fall from the ceiling, and the only light comes from flickering tallow candles or glowing fungus.

☠ Threat

Slythrik the Scale-Caller, a winged kobold sorcerer, rules the mine with an iron claw. He seeks to awaken a slumbering elemental force within the quartz to elevate his tribe to draconic status. His obsession makes the mine a gauntlet of lethal traps designed to sacrifice intruders to the stones.

History

Founded by the Oakhaven Mining Consortium a century ago, Hollowvein was closed after a series of unfortunate collapses. The truth is darker: the miners dug too deep into a vein of corrupted quartz that drove them to madness. Now, a kobold tribe uses the cursed crystals to fuel their primitive sorcery and defend their stolen territory.
