Great War

The Great War, also known as the First Contact War and the First War, was a destructive conflict fought between the zerg and protoss, created by the progenitor race as ancient enemies, with several factions of terrans being caught in-between.
The Great War saw the dethroning of the Terran Confederacy by the Terran Dominion as the most dominant terran force and the establishment of a puppet government in 40% of the Terran Confederacy by the Novayan Stellar Commonwealth as part of its initiatives in the centuries-long war against the Sith.
