When freed, Izual informs the player that it was he who told the [[Prime Evils]] of the [[Soulstone]]s' power and that the demons had been behind this immense plan to gain the power of the stones. With this information, Deckard Cain urges the player to destroy [[Mephisto]]'s Soulstone at the [[Hellforge]]. The Forge is guarded by [[Hephasto]], the Armorer of Hell, and the player has to kill him to destroy the Soulstone.
