The Judas Pain is an object of great power in the world of Bastard
When the gates of Hell were closed, they were sealed with an immense power. This power was the Judas Pain, and was the only thing that could unlock the gates. However, this power was broken into several fragments. The first fragments were placed in the hearts of the Kings of Hell, while the remaining one was placed in the heart of the Adam of Darkness, Dark Schneider.
