Known to humans as the angel who cast Lucifer into Hell, he is not what he seems. Ruthless and cold on good days, and downright sadistic on bad days, he is a handful to even the most patient of the angels.
He keeps to himself, and is close to only a handful of angels, preferring to be alone with his pupils or away from everyone so that he can remain as calm as he can manage.
With a temper to rival the devil himself, he makes enemies more easily than friends, and is almost incapable of showing his emotions even when he wants to. He is not hard all the way through, but his gentle side is so rare a sight that most angels believe that it is a myth created by Gabriel to defend his right hand.
