"You know there's magic in the world now." John leaned his head back, but kept looking at Danny. "There's good and bad, but all magic is powerful. It costs to use it, and sometimes things go pear shaped. There's an entire other world you've never noticed...but you will now. People you only see out after dark. People who up and vanish when the moon is full. People who are really hostile to the church. You've met them. You just didn't know he was a vampire or she was a witch. And then thre's creatures from other realms that come to bring down destruction. Consume souls. Those are the ones I concern myself with."
