(This is a crossover with Darksiders. Do note that it has a rushed ending. Just so you know.)
After bringing the last heart of the chosen ones to Samael, War enters the portal created by the demon prince in order to gain access to the Tower of Souls. Unfortunately, some outside force distabilizes the demonic magics keeping the portal's world stable, and War rushes towards the exit, much to the fear of the Watcher. After exiting it and landing in a very dark environnment, the horseman is greeted by a giant beast which rises behind him.
How will the horseman of the apocalypse return to his world and restore the balance while he remains stuck in an unknown and strange place? What does queen Chrysalis want with him anyways?
