God is powerful. God is wise. God is long-lived. In these qualities, He is greater than any being there ever would be. However, God is not immortal. The perfect systems he had in place to protect the world from evil die with him, leaving only angels and their patch-solutions to protect the world.
Four youths find a pentagram in the woods and a book of spells in the woods. What could go wrong?
