Duriel, the Lord of Pain

Deckard Cain

Diablo



Duriel is the twin of Andariel. I believe that they conspired together to assist Diablo in releasing Mephisto and Baal, though they had both supported the Lesser Evils in the past. The Lord of Pain was found guarding Baal's prison–the tomb of Tal Rasha–when he was slain by heroes.
