Since the conflict began in the Koprulu sector, the ruling council of the United Earth Directorate has closely monitored its wayward Terran colonies.
Having witnessed the steady advancement of the Zerg infestation and the maneuverings of the Protoss throughout the Colonies, the ruling council has finally agreed to take control over the war-torn sector.
Learning that a new Zerg Overmind has manifested itself upon the planet Char, the UED has sent its greatest Admiral, Gerard DuGalle, to capture the creature.
As Captain of the UED fleet under DuGalle, your objective will be to storm the Terran Dominion and depose of its dictator, Emperor Mengsk I.
After Zeratul and Artanis complete channeling the energies of the Xel’Naga Temple in planet Shakuras, they inserted the Uraj and Khalis Crystals into a mechanism that triggered a massive shockwave off the Xel’Naga Temple — eradicating the Zerg from Shakuras.
The nefarious Zerg Overmind has been destroyed and the Protoss homeworld of Aiur now lies in smoking ruin.
As the Executor of the remaining Protoss forces, you must now attempt to reunite your beleaguered people and save them from the ravenous Zerg who still roam mindlessly across the blackened fields of Aiur.
