Changes

* The heroes follow Baal to Mount Arreat for the final conflict between man and the last of the [[Prime Evil]]s. Although the heroes defeat Baal, his demonic army continues to advance.

* The [[archangel]] [[Tyrael]] discovers that Baal has succeeded in corrupting the [[Worldstone]] housed within Mount Arreat. Realizing that the Worldstone cannot be restored, Tyrael reluctantly destroys it. The resulting explosion destroys Mount Arreat, ravages much of the countryside, and decimates Baal's army.
