Hezekiah fell from grace and lives his life on earth as an ambiguous (half angel, half demon.) He finds himself in the middle of a war between Lucifer and Hades to bring back the blue dagger to Jerusalem, and restore the balance between the pure (good) and the damned (evil).
In the midst of this, he falls in love with Feyrah, a fairy nymph, whose colony is destroyed by the very evil Hezekiah is trying to obliterate. When he has to save her and the blue dagger, he has to make a choice that will effect the entire world.
