In the year 1604 of the Continental Calendar, the Warring States Period, which had actually lasted for three centuries on the Philbist Continent, came to an end with the collapse of the northern overlord, the Jaz Empire. The troops deployed included regular knights and soldiers, magicians and chaos divisions, and mercenaries, totaling 620,000. In addition, a large number of magic weapons including three space fortresses, the Abandoned Beast Corps, the Sky Dragon Cavalry Corps and other special combat forces were also dispatched without reservation to completely annihilate the Jaz Empire, which was called the "root of all evil."
