The Song of the Serpentine Angel

When an angel falls, it becomes one of two things: a Fallen Angel or a Demon.

Or,

Maybe we were wrong about how Heaven and Hell operate. Maybe things aren't as black and white as people once thought. Good and bad are much more intertwined than many people want to accept. After all, if your God is supposed protect from that which is evil but that which is evil often masquerades as "just and good", who are you supposed to trust?

Or,

A fallen angel carves itself a new destiny.
