The Great Conflict was a feud between Team Aqua and Team Magma of the Hoenn Region. Team Aqua renowned for having the goal of expanding the surface area of the seven seas for inexplicable reasons. Team Magma, in contrast, wished to enlarge the land, also for inexplicable reasons. To accomplish these goals, both teams sought out the orbs of the mythical beasts of the leviathan and the behemoth, known respectively as Kyogre, ruler of the seas, and Groudon, guardian of the land.
The core event of the Great Conflict was a battle between the aforementioned legendaries, and the leaders of the two teams. Through an unknown course of events, Team Aqua lost any control they had obtained over Kyogre, and the leviathan began a rampage the likes of which Earth had never before known.
Team Aqua, recognizing the impending disaster, fled to their Base. Using their advanced technology, within the following weeks they orchestrated a takeover of Team Galactic (see TEAM GALACTIC), a terrorist group well-known in the region of Sinnoh. Team Galactic had recently lost contact with many of its major leaders because the group had broken up after a plot of theirs had been foiled. Team Galactic, unprepared for the attack, was forced to evacuate headquarters and surrender all equipment inside said headquarters.
Team Galactic, notorious for their explorations of the universe, had several installments in place for other worldly travel. Taking advantage of the new technology at their disposal, Team Aqua fled Planet Earth and to Galactic's Spaceport, located on the outskirts of Earth's atmosphere. By this time, Earth had completely flooded.
There are no known survivors other than the members of Team Aqua and their Pokemon. Several species of Pokemon disappeared from existence. Save for a scarce few that were able to find any land left or Pokemon belonging to Team Aqua, the Pokemon now on Earth are predominately of the Water type (see WATER). Because of this, many species of Pokemon have ceased to exist. Pokemon that were referred to as "wild" are no more seen by humans, as humans have not since nor are able to return to Earth—the only place known to have Pokemon that are outside of human control.
Team Aqua, a group of hundreds of members, saw almost immediately that the Spaceport could be no more than a temporary home. The supplies they had taken with them, as well as the supplies already on board from Galactic's use, would not be enough for more than a few months. Thus, using Galactic's superb technology as well as their own, they began to search for another place to call home.
The Planet Nia had been previously discovered by several astronomers on Earth; however, it's rough, rocky terrain made it absolutely impossible to explore. The very idea of exploring the planet was discarded immediately, being called by several famous astronomers as "idiotic", "a horrendous venture", and as "a waste of materials and money". Thus, the idea of exploring it was tossed aside, and scientists chose to ignore Nia for the most part, deeming it uninhabitable.
However, the Planet Nia is placed as Earth is around its own star, which allowed for speculation of the possibility of life. Seeing this as the only possible way to survive, Team Aqua arrived on Nia as the last of their supplies ran out. While scouting out Nia to see if it was indeed livable, they discovered that Pokemon like Tropius (see TROPIUS) were in fact very useful, as they could eat the food that is naturally grown on the Pokemon.
Team Aqua settled on Nia, finding sparse, but livable amounts of water on the planet, as well as strange foods unknown to Earth, but still edible (see PLANT LIFE). As generation passed, they began to build Nia with the technology they had to resemble Earth. However, rather than resembling Earth, the results far surpassed any of Earth's technology.
Hundreds of years passed until the whole of Nia was populated by descendants of Team Aqua. Over time, several individuals decided to embark on journeys to other planets to see what raw materials they could find. Several more planets that could support life were discovered in this galaxy (see UNIVERSE), as well as planets in far away galaxies. Space travel became common to everyday citizens. Space "ships" were built for travel from port to port between planets. These ships transported goods, supplies, and raw materials between planets. Planets became very dependent upon the transport of these goods, thus it is imperative to have for present-day survival.
When the Great Conflict ended, the era then entered was known as The New Generation, the period in which human population spread across, engulfed, and modernized the Planet Nia. This era lasted for several hundred, if not a thousand, years, and then it entered The Restoration.

Thanks to Hragon who not only convinced me to write a Pokemon fanfic, but also helped me with the plot and the prologue.
