Baldur's Gate II:EE

Kidnapped. Imprisoned. Tortured. The wizard Irenicus holds you captive in his stronghold, attempting to strip you of the powers that are your birthright. Can you resist the evil within you, forge a legend of heroic proportions, and ultimately destroy the dark essence that haunts your dreams? Or will you embrace your monstrous nature, carve a swath of destruction across the realms, and ascend to godhood as the new Lord of Murder?
