<blockquote>''You are a worthy hero. We augment your skill and grant you entry to the interior of Mount Arreat, wherein lies the Worldstone. Beware, you will not be alone. Baal, the Lord of Destruction, is already inside. The Archangel Tyrael has always been our benefactor, but even he cannot help us now, for Baal blocks Tyrael’s spiritual presence from entering the chamber of the Worldstone. Only you, mortal, have the power to defeat Baal now. Baal threatens the Worldstone, and through it, the mortal realm itself. You must stop him before he gains full control over the sacred stone. With it under his control, Baal could shatter the boundaries between this world and the burning hells, thus allowing the hordes of the prime evils to pour forth into the mortal realm like an unstoppable tide. If you are weak, the world as you know it could be lost forever. You must NOT fail.</blockquote>
