Samael, the angel of death from my novel Death. Tired of the hypocrisy of heaven, and the lies that God has fed him, Samael decides to cast aside his role as a seraphim and a servant of God. As he descends, the white of his wings and his clothes burn away into ash, revealing pure blackness beneath, as though it has always been there.
Samael is a very complicated character of mine, and crosses over into the Incubus Lessons storyline as well.
