Legacy of Fire
Halruun was the old high priest of Sarenrae who first fell victim to the ministrations of Xulthos decades ago.
The tainted cleric turned his congregation to hatred and murderous evil, and as a result he was one of the first villains slain by the Pactmaster Guard in the final assault on the village.
Death was not to be his final punishment, however, for as a formerly goodly cleric who fell to evil, his soul was cursed to return to the world as an undead creature known as a huecuva.
During the day, Halruun hides his true form with disguise self.
