Batman's tried everything on Earth to stop the menace hunting his friends and family...now it's time to turn to things not of this Earth! In the past, whenever Batman's encountered the supernatural, he's turned to Jason Blood for guidance-and to Etrigan, the demonic entity living inside him! But securing their help is never simple, and what Blood has to show him will shake Batman to his core!
