Nearly four hundred days had passed since the incident where Diablo had ended the existences of seven Universal Masters and six Main Entities from their respective universes.
Over the months that followed, the armies of the Divine Alliance and the Infernal Coalition traversed billions upon billions of light-years in their coordinated advance towards those seven universes.
All factions knew that Diablo and the forces of Hell he controlled were up to something, but they also knew that regardless of whatever Diablo was planning, they had no choice but to dive headfirst into it, especially since it was most likely going to be a trap meant for the members of the Divine Alliance.
For those belonging to the Infernal Coalition, they hoped to take advantage of whatever damage Diablo dealt to the Divine Alliance, weakening them even further and allowing themselves to emerge victorious in the war.
