The very theme of the game. Remember that this takes place in the New World of Darkness: a Crapsack World where evil practically has already won; where creatures of the night hide everywhere, manipulating mortals to their own ends; where the closest thing we have from good guys are at best naive idealists who won't stay alive for long, and at worse just as bad as the ones they fight. Overall, a place with no hope, no real chance of improvement. Princess essentially punches this notion in the face and says "screw that, we can change this world, and we will do it, not matter how hard it is." Nobles might be fighting an uphill battle, but they won't just give up.
This game makes the Apollo landing one even more than it already was in real life. In addition of being a big accomplishment by itself, humanity accidentally broke the Dreamland prison in the process, freeing the Radiant Queens and causing a resurgence of Princesses in the world. They literally brought hope back to the New World of Darkness, in more ways than one.
The Wardens used to be in charge of the Dreamlands, hiding everywhere among its inhabitants to constantly adapt the illusions and make sure everyone stayed here. When the Apollo landing broke the prison, the Radiant Queens saw through their masks. They reacted by assembling their armies and brutally kicking them out, taking over the Dreamlands as their own territory.
According to the crossover section of the wiki, some Princesses of Spades managed to trick True Fae into oaths preventing them from ever returning in the real world. Did You Just Scam Cthulhu? at its finest.
