Tyrael, an archangel, is one of the main characters seen in the popular game Diablo II. He is depicted as an angel whose face is hidden by the darkness of his hood and never revealed throughout the game. He has large tendril-like white-glowing wings and is garbed in brown and gold robes. (In the game's various cinematic sequences, he is also at times depicted wearing armor over his robes.)
Tyrael is one of only three named angels shown in the game; Hadriel is found in the River of Flame, in Act IV, on the player's path to destroy Diablo, and Izual is a former (corrupted) archangel.
Tyrael (pronounced "Tear-ial," as Marius enunciates in the cutscene "Terror's End.") comes from the High Heavens and serves "The Light", the forces of good in the Diablo universe. It is unknown who his superiors are; no gods or higher angels are ever named. Judging from Deckard Cain's description, Tyrael seems to be regarded as something of a rogue by the forces of Heaven, as he seems to intervene in the affairs of mankind more frequently than is considered appropriate. This would seem to explain Tyrael's greater sociability, compared to Hadriel, as well as his willingness to single-handedly engage one of the Prime Evils directly.
