Welcome… to Gamindustri. But not the same Gamindustri as before. Before was a land ruled by goddesses all competing with each other for greatness and the privilege of becoming the best and most powerful in the land. Before was a land where each goddesses' mettle was tested by their personal skills and power - their prowess representative of the nation they led. Before was a land that lived in relative harmony under the guidance and protection of the goddesses that ruled over.

But here, in Wars Dimension, Gamindustri is a land where each nation is locked in a near-perpetual and frequent state of conflict. Colorful, light-hearted, and orderly conflict no less.

In this world, the goddesses of each nation lead armies into battle, with command of land, sea, and air as the nation's commanding officers, or COs. Their proficiency in battle now replaced with skills of leading armies; their divine powers now aiding their troops rather than themselves.

Wars have begun and ended as routinely as the sun rises and sets; alliances have formed as frequently as pacts have been broken. But no matter what, the situation has yet to change until it was ultimately accepted that so long as the nations exist, so will battle. And as long as battle exists, so will the nations that inhabit Wars Dimension. And while the conflicts that raged were not of annihilation or conquest, they were still a competition over the land's supply of Share energy.

But eventually, this will all change as one day, one dared to upset the world balance with thoughts of utter and total domination of Gamindustri and its Shares. When the balance of power will be almost tipped and the peace held by perpetual conflict among equal powers would now be thrown into disarray and chaos.

That day, a new power will rise to challenge the status quo.

That day, the skills and commitment of all nations and their goddess COs will be tested.

It was also on that day, that Planeptune received two new rookie COs.

HistoricHippos:

In case any reader didn't get the idea already, this is a crossover fic between Neptunia and the Advance Wars series. This is not - I repeat - NOT going to be a dark, gritty war-fic as you might've assumed by reading the title or the prologue. This will not delve into the horrors of war or any of that stuff. Suffice to say, if the Advance Wars games (pre-Days of Ruin) didn't really touch on those subjects, then neither will this story.

That said, as this is a crossover, just imagine this as a Neptunia game/story that just so happens to be reimagined as an Advance Wars game with appropriate stuff and game mechanics (or as best as I can interpret and adapt them). The mood will attempt to emulate that of the first two or three Advance Wars (so this story won't be as serious as Days of Ruin, but that is not to say that everything from Days of Ruin will be completely ignored). Other than that, happy reading!
