The combined forces of Freedom Fighters and unified Protoss entered the portal into the fantasy world of Fantasia.

Archimonde managed to extract the location of Char from the dead Overmind and led his Legion to purge every Zerg on the planet driving the Swarm to extinction. The army of demons claimed domination over the home worlds of the Zerg and Protoss. The demons' next target was Fantasia as they already knew their way to the world.

Unknown to the Terran Dominion, Raynor's Raiders, the Freedom Fighters, the Protoss, and the Burning Legion; the Zerg race was not completely wiped out. Only Zeratul knew that the surviving Zerg resided in a planet, Zerus, the birth world of the Zerg. They became primal to resist the incorporation into the Overmind's Swarm. The Primal Zerg continued to prosper, hunt, and evolve.
