At the end of [[Diablo 2]], when it was clear that [[Baal]] had permanently corrupted the [[Worldstone]], Tyrael decided that the only thing he could do to protect [[Sanctuary]] was to destroy the sacred relic. The destruction left [[Mount Arreat]] as nothing more than a crater, and dealt a devastating blow to the [[Barbarian]] tribes, who saw it as their life duty to protect the Worldstone. {{iw|[[Anya Anya}} ]] however considers this strange and tells us in her valediction that this action was never foreseen in the prophecies.
