User:144-Patient Appelant/Orionus War

The Orionis War was an intergalactic conflict beginning in 2634 between the United Galactic Alliance and the Jiralhanae Empire. Started by Jiralhanae attacks on UGA colonies, the war consumed multiple different races and led to the near annihilation of a few. Also during this time, the UGA unleashes Apex in desperation and, as a result, actually causes more deaths on their side than on the Jiralhanae side. The war affects the entire Orion Arm of the galaxy and even possibly the entire galaxy as it leads to the discovery of Purgatory, an installation left behind by the Forerunner.
