"The continent of Ignas, in the northern hemisphere of our world. On this, the largest continent, a war has been raging between two countries for hundreds of years. In the north of the continent lies the Kislev Empire, in the south lies the desert kingdom of Aveh. The war has gone on for so long that the people have forgotten the cause, knowing only the pointless circle of hostility and tragedy. The chronic war obsession was soon to encounter a devestating change. This was due to the 'Ethos', an institution that preserves our world's culture, repairing tools and weapons excavated from the ruins of an ancient civilization. At once both countries excavated these ruins, and had the 'Ethos' repair the discoveries, in order to increase their military power."

"The various weapons excavated from the ruins greatly changed the form of warfare. The outcome of the battles between the two countries was no longer determined by man-to-man combat, but by 'Gears' - giant humanoid fighting machines - that were obtained from deep within the ruins. Eventually, after continuous swings in the state of the war, Kislev gained the upper hand. The major factor behind this lay in the enormous difference in the amount of resources buried within their ruins. But suddenly a mysterious military force appeared in the continent of Ignas. Called 'Gebler', this force decided to make contact with Aveh. With the assistance of this Gebler military force, Aveh was able to recover from being hopelessly outnumbered to being back on an even standing with Kislev, then, taking further advantage of its newly gained momentum, Aveh started to capture one territory after another from Kislev, showing no indication of slowing down in their invasion campaign."
