The Storm-Etched Caverns
The air smells of ozone and the walls hum with the fury of a captive hurricane.
A massive subterranean network of limestone caves infused with volatile elemental energy. Jagged crystals of lightning quartz sprout from the rock, casting a flickering blue radiance over everything.
The cavern constant vibrates with a low-frequency hum; the smell of burnt hair and ozone is pervasive. Visibility is marred by frequent arcs of blue lightning and a shimmering haze of static charge.
☠ Threat
Fulgorath the Sky-Reaper, an Elder Tempest of unimaginable scale, seeks to consume enough electrical energy to shatter the crust of the world and ascend back to the heavens. Its presence creates a constant electrical field that disrupts magic and strengthens elemental minions.
History
Deep beneath the earth, a natural convergence of ley lines once acted as a drain for elemental excess. Eons ago, an elder storm spirit from the Plane of Air was snared in this geological trap, and its presence has since mutated the caverns into a crackling tomb of eternal electricity.
