Tyrael

Tyrael is one of the main characters seen in the popular game Diablo 2 of Blizzard Entertainment. He is depicted as a hooded angel, whose face is completely impossible to see because of the darkness provided by his hood, with tentacle-like white-glowing large wings. He was imprisoned by Diablo.

Tyrael guides the player throughout the five Acts, providing advice and knowledge. During the end of Act 5, Tyrael destroys the World Stone in order to prevent Baal from corrupting it any further.
