The First Elysian War was a conflict between the Elysian Celestial Empire and the newly-formed Yamatai Star Empire that took place from around YE 01-YE 08 as Yamatai consolidated its control over the Yamatai (Planet) (aka Geshrintall).

During this war:

• Yamatai stole the treasured Soul Transfer technology from the Elysians because, at the time, the Uesureyan Star Empire wouldn't give it to them.
• Elysians killed Emperor Ketsurui Saito and Ketsurui Yuki
• Elysians are blamed for a PNUgen Corporation created virus which killed 20 billion Geshrin in YE 08
• Yamatai responds by declaring Elysian civilian targets as acceptable and its miltary shoots down most of the Heavens, killing countless Elysians.
