Losing the war would be a tragic disaster for the losers, except in one scenario: if the conqueror of Twyluxia decided to stay and further improve their Ordeal rating.
In this unlikely event, turning the tide wouldn't be just a dream. If Jake, the future supreme ruler of Twyluxia, were to be killed or forced to leave the Ordeal by a losing Mirror Universe Player, his accomplishment would automatically transfer to them.
At that moment, all the remaining Players from the losing side would see their Main and Global Mission accomplished. This was one of the few loopholes allowing Players from each camp to simultaneously achieve their Main and Global Missions.
Sadly, exploiting this flaw was easier in theory than in practice. Fortunately, Jake was the kind of crazy person who might stay just to scrape up a few extra points.
