Peace. Law. Order.
"Let it be known that freedom will not perish; that we will fight until the very last man to topple the Confederacy and that we are responsible for the destruction at the Tarsonis Ghost Academy. We are the Sons of Korhal."
The roots of the Terran Dominion spring from the Rebellion of Korhal, a "terrorist" faction which emerged when the Terran Confederacy put down a rebellion against them on the world of Korhal. The Confederate attempts to weaken the Rebellion backfired when they slew its first leader; Arcturus Mengsk became its new leader and was even more effective. When Mengsk forged an alliance with the Umojan Protectorate, the Confederates destroyed the world of Korhal using nuclear weaponry. Mengsk renamed the Rebellion the Sons of Korhal. The rebel movement fought against the Confederacy, allying themselves with former Confederacy Alpha Squadron leader General Edmund Duke and eventually destroying it using psionic devices to lure the zerg to the Confederate homeworld of Tarsonis. This action alienated two good-hearted Sons of Korhal officers, Sarah Kerrigan and Jim Raynor. The former was abandoned to the zerg on a space platform over Tarsonis while the latter defected with a rebel movement.
