A Fallen Angel

As angels look down to the worlds below them, they have to abide by the rules set out by the higher circles of their kind. If you don't respect the rules, it will brand you as a Fallen, an angel unworthy of its wings. Fallen Angels are usually corrupted creatures without conscious or compassion...

Caitlin on the other hand, is an angel who was deemed Fallen because her compassion drove her to save a soul. What happens if she's forced to live in the immortal and mortal worlds combined, next to the very thing she had saved before?

What happens if she has to live with Vampires and Demons alike?
