'''Tyrael''' is an [[Archangel]] and a member of the Angiris Council, who rebelled against defied heaven in order to teach the [[Horadrim]] how to seal the [[Prime Evils]]' souls into [[soulstone]]s, thereby trapping them for eternity. He was captured by [[Baal]] after he failed to stop [[Diablo]] releasing Baal but was eventually freed by the adventurers of [[Diablo II]]. He returned to the adventurers in the [[Pandemonium Fortress]], the last bastion before [[Hell]], to offer some assistance.

When it was clear that Baal had permanently corrupted the [[World Stone]], Tyrael decided that the only thing he could do for is to protect Sanctuary was to destroy it. The destruction left [[Mount Arreat]] to as nothing more than a crater, and put dealt a devastating blow on to the [[Barbarian]] tribes, who saw it as their life duty to protect the World Stone.

Tyrael has been missing for the last 20 years, and none nobody has heard anything about him.
