World Building / The Great War Of Starborn Unification

After the Starborn unified, they lead a war against the city of Collosi for attacking them. This was known as The Great War Of Starborn Unification. They attacked the city by storming the Collosian border and sending troops into the city. The Piangeni responded by sending armies of Collosi. The Collosi fought the Starborn Army fiercely, but the Starborn were too powerful for them. After two days of fighting back and forth with swords, the Piangeni surrendered. But this was not the end of the war. Two days later, they sent an army of Collosi to attack the the Starborn. This led to The First Collosi War. (see details on separate page)
