Lord of Terror (Diablo)

Class: Prime Evil
Appears in Act IV

After all of the seven Great Evils are sealed in the Black Soulstone, it is revealed that Adria had actually been corrupted by Diablo, having born him a child when he possessed the Dark Wanderer. She uses Leah, Diablo's daughter, as the vessel for the Black Soulstone. Diablo is reborn as the Prime Evil, essentially Tathamet reborn. He lays siege to the High Heavens and begins to corrupt the Crystal Arch, but is foiled by the efforts of the very group of heroes he had manipulated into reuniting the demons in the black soul stone. His plans had been undone by mere mortals. As he plummeted from the Crystal Arch, Diablo's body disintegrated, leaving the Black Soulstone to fall into the clouds of the High Heavens; Tathemet's essence was banished forever, ending the Great Conflict once and for all. Or so everyone else would like to believe...
