As tensions continued to escalate between the major powers during the first half of the 21st century, Japan began building an underground structure to protect the nation from the threat of complete annihilation. In 2020, the world was thrown into complete chaos. Protected by its anti-ballistic missile systems, Japan's metropolis withstood the flurry of nuclear warheads launched upon its soil. However, bioweapons were unleashed on the Japanese people, eradicating millions in a short span of time. Nuclear weapon engagements elsewhere caused a global disaster known as The Nuclear Winter. In 2035, unforeseen problems led contingency supplies in the underground network to dwindle at dangerously low levels. A charismatic young man led a small band of survivors outside the underground shelter to assess the inhabitability above ground. Several years later, one man from the original group returned to the shelter and rallied a selected few to the outside, claiming dangers still existed and the new group will be the vanguard of mankind’s survival. It is 2071 and a religious group called Sanctus Ordo Lumina has an iron grip on Novus Tokyo, the only city in the wasteland formerly known as the Japanese archipelago. Smaller settlements outside Novus Tokyo struggle to survive as Sanctus hoards the majority of resources. This stranglehold gives birth to a rebellious faction - the God’s People Army. However, the founding of the GPA is shrouded in mystery and the truth behind its intentions to liberate may be beyond what meets the eye.
