Chapter 7: Doom of Ythryn - Icewind Dale: Rime of the Frostmaiden

Chapter 7: Doom of Ythryn. Ythryn rests in the silent depths of the Reghed Glacier. Ice encloses the enclave on all sides, yet the magic imbued in its stonework shields it from utter destruction.

Iriolarthas endures as a deteriorating skull that drifts about the necropolis in lonely despair. Wispy symbols of the eight schools of magic form above it and quickly dissipate. A demilich is what becomes of a lich that neglects to feed souls into its phylactery, and Iriolarthas's phylactery has been empty for nearly two thousand years, buried under the rubble of Ythryn far from the demi...
