Vurnthrik occupies the Rotting Lowlands, a poisonous southwest basin where acid marshes lap against cracked basalt and sulfur fog crawls through the reeds. Above ground, isolated causeways connect watchposts, stills, and hidden camps. Below, shadow-towns descend into volcanic caverns where House agents, assassins, and alchemists serve Draknaar through secrecy and calculated cruelty. The region is poor in comfort but rich in leverage, its every trail, toxin, and whispered name part of a larger covert network.

Field Observations

Unprotected travelers must frequently test against fumes, contaminated water, and sudden acid spray.,Reliable routes depend on local guides who read buoy markers, vapor color, and submerged stone paths.,Cave roads can bypass the worst marshes, but they are narrow, guarded, and vulnerable to ambush.

Basalt-cave communities blend Draknaari law, undercity customs, and survival practices shaped by toxic wetlands.
