Description
Mordrath Keth is a tall, narrow skeleton draped in crimson funeral robes, with an iron crown fused to his skull and blue witchfire burning in his eye sockets. Chains of broken prayer beads hang across his ribcage, clattering whenever he moves.
Equipment
Tattered crimson robes, an iron signet ring, a black crystal phylactery hidden beneath the valley church, and a bone wand
Hook
The church's buried foundation contains Mordrath's phylactery, but destroying it also releases the trapped souls of everyone the lich has sacrificed there.
Motivation
Mordrath desires the destruction of the church and village in the valley, believing their faith sustains a divine presence that prevents his dominion over the region.
Personality
Coldly methodical and contemptuous of compassion, Mordrath speaks like a magistrate delivering an inevitable sentence. He prefers to corrupt symbols of hope before destroying those who cling to them.
