The Gate Incident occurred in year 2032, following the outbreak of nuclear—more precisely, atomic—war, commonly referred to as World War III (WW3). The convergence of three atomic bombs detonating in the stratosphere, mere milliseconds before a powerful solar flare struck Earth, created the perfect conditions for an unprecedented event: the formation of a dimensional rift allowing tides of fierce magical beast to flood into earth; over 50% of the global population had perished, and the majority of human civilization lay in ruins. It took 8 long years of relentless warfare, before the situation began to stabilize and humanity finally reclaimed their world. Fast forward to present day in the year 2674 humanity begin to slowly shift their focus from colonizing planet and clearing dungeon to preparing for a grand war against the 3,000 world's and the Constellations.
