## Demilich
*What Lies beyond Lichdom*
- **Habitat.** Any
- **Treasure.** Arcana
A demilich is a skull harboring the remnants of a lich's wicked essence. If the burden of immortality overwhelms a lich, its consciousness turns inward as its body rots away. But if its remains are disturbed, a demilich rises. Demiliches usually appear as skulls adorned with gems or arcane sigils.
### Demilich Lairs
Demiliches jealously guard their deathtrap-laden sanctums. The most notorious of these is the Tomb of Horrors, lair of the infamous Acererak.
