Alex and his group need to get rid of the artifact that would bring hell on Earth.
But to do that, they need to go to hell themselves. They escaped the realm of the undead but they know that they can't keep running any longer.
With Mammon, Astaroth, and Baphomet looking for them, going to the nine hells in order to destroy the book that will unleash the Hellfather, will be an impossible task.
Our party will need to upgrade their classes and equipment. They will need the help of an angel, and every single magic item they got, to make it work.
In the future, the arena is about to be painted with the blood of the revolution.
This is the culmination of Alex's adventures and where the two timelines finally meet.
