Origin

𝗢𝗿𝗶𝗴𝗶𝗻: The Arc-System was a network of sapient machines created by the Nasorian species, in answer to a request from the Eteriens, for the purpose of stabilizing the fragile Dimension 25 and ensure that Time and Space won't collapse as well as to help other species to advance. Because of that every unit in the Arc-System got its own second function; some were turned into architects, weapons, recorders and even into Nova Coffins in case the species that currently exist go extinct. Afterward the Nasorians sent their creations all across the dimension where they began service.

A few times after that there were individuals who tried to use the power of the Arc-System to oppose the Eteriens and take them down. Those uprisings caused the Elders to limit the Arc-System and put heavy restrictions on them as well as banning several from being put into service. Despite that one of the younger Eteriens named Tray managed to get hold onto two banned Arc-System Codes named Lofty and Diablo, which he hide in his personal dimension to ensure that no one will be able to get them unless he chooses so.

Eventually, Tray's Dimension was found and attacked by a mutated Arc-System wielder, named Xyoz, because of that Tray was forced to flee to Dimension 13 where he gave the devices to his wards along with a third Code: Chaser who was specially given by the Nasorians to protect them and make sure that the Eteriens won't notice the banned ones.
