Synopsis for "The Demon Bound"
In Hell, Etrigan is taunted by Lucifer who says Etrigan is stranded in limbo and unwelcome on Earth and in Hell. On Earth, in the Fortress of Gibraltar, Vandal Savage tortures a mute Jason Blood, taunting him by telling him of how Etrigan fired Xanadu's passions more than Jason. Meanwhile, Horsewoman, Shining Knight, and Exoristos set out from Al-Wadi to rescue Jason in order to recruit Etrigan in their fight against Cain and his army of vampires.
Upon their arrival, Exoristos distracts Savage, catching up over a test of strength, while Shining Knight rescues Jason. Horsewoman convinces Savage's mount to not pursue, buying enough time for their escape. Days after their escape, Jason Blood leads the group to Italy where they are reunited with Xanadu. Meanwhile, in Hungary, the bounty hunters that captured Horsewoman meet their end when Cain's army falls upon them.
