The year is 2055. Virtual Reality has been around for nearly forty years, and the Full Sensation Dive System has been around for about thirty. The various countries of Earth have long since given up on Warring against each other in this dimension when it turned out that with the FSDS (Full Sensation Dive System) virtual worlds became real, especially once Richard Alonzo Albeque's AIQNPC (Artificial Intelligence Quest and Non-Player Character) System was released and spread like a wild virus across all the active MMOs. People vanished from their Dive system, leaving nothing behind of the person they were, and the Characters they were in game become locked out, and no longer responsive to the System. In addition to this, they are suddenly showing up on ALL servers of a game at the same time, almost as if they were now an NPC. The governments put a stop to all distribution of FSDS Technology, and keep an eye on these 'Digitized Players'. Ten years pass and one of the first ever Digitized Players, a Level 500 Catgirl by the name of Atreya the Dawnbirth, created a stable portal between their MMO and Earth. With the return of one of the players, the governments remove the bans on FSDS Technology, which has still been researched heavily while under the ban. Wars break out over control of Virtual Worlds, but these wars are all fought ON the Virtual World, so the Earth isn't polluted further. Immortality is now available to all who seek it, if you can find a World to call your own. Of course, nobody paid attention to one of the few warnings Atreya brought back with her... The NPCs sometimes became sentient and disobeyed coding laws.
