Battle Of Idaria
In 2487 BC, Idaria made contact with the Koaliv Empire. After refusing to give up their planet to them, Idaria managed to hold the Koaliv off for a while but eventually was overwhelmed by the orbital bombardment of their planet. After refusing to surrender, The Koaliv Empire used the experimental super weapon known as the Stellar Monarch to not only destroy the planet, But accidentally destroy 57 solar systems and most of the Koaliv Empire's Eastern Fleet, Leading to the formation of the Galactic Revolution.
