Negative Energy Plane

Infinite darkness. Travelers here cannot see, even with darkvision. All lights are snuffed out. Any traveler here takes 2d6 necrotic damage each turn. When a being reaches 0 hit points, they whither and die, their soul is lost and immune to resurrection, and their lifeless husk becomes a mindless undead. Xeg-yi live here and the Dustmen keep a citadel here through great effort.

All creatures here are immune to radiant damage and all healing is negated.
