Premise: "The world is being invaded by another realm's angels," but with a twist.

The angels are, in fact, fallen angels from this realm. They were banished to a desolate realm where they were brutally treated and punished. The angels are seeking revenge, and they'll stop at nothing to destroy the world they were cast out of. The humans are divided, with some believing that the angels will bring salvation and others thinking they'll bring destruction. The fate of the world hangs in the balance as the angels prepare to invade.
