The Great War for Nara

The Great war of Nara lasted from 1864 U.O-1920 U.O. The war was started over after the Revolutionary State of Acrabia rebelled from the nation of Orbis in late 1863 U.O. Several nations joined in their respective sides to honor the their military alliances and the world was thrusted into chaos. The War would end in 1920 U.O with a treaty called "Humanities Signature". This treaties purpose was to prevent a conflict like this from ever starting again. However the damage was done and almost one billion lives were lost with only a little over one hundred million dying from warfare, and the rest from famine, sickness, and crossfire.
