In a place like Arkham City, a church may be little more than just another abandoned building. Nevertheless, for a group of innocents, Gotham police, and one very guilty Mayor Sharp, it's where they've come for sanctuary. A gathering mob doesn't feel that way, but a mysterious protector will show them otherwise. As inmates try to break down the church door, reporter Vicki Vale digs deep into the origins of Azrael--who has suddenly appeared to save them from the mob outside. What's his connection to security guard Aaron Cash? The inmates have a secret weapon to try and enter the church: BANE! With his massive, Titan-fueled strength, will even the mighty Azrael be able to stop him?
