For nearly 300 years, humans thought they were alone in the Koprulu sector. / They were wrong. / The zerg emerged, seeking to consume all in their path. / And before long the protoss, a highly advanced alien race, began wiping out infested worlds, burning zerg and terran alike. / A three-way war… unlike anything humanity had ever faced… / …erupted almost overnight.
All the while… a human civil war raged. / Marshal Jim Raynor vowed to oppose the corrupt dictator Arcturus Mengsk for the betrayal of the woman he loved… Sarah Kerrigan.
Kerrigan: Uh, boys? How about that evac?
Raynor: Damn you, Arcturus! Don't do this.
Mengsk: It's done. Helmsman, signal the fleet and take us out of orbit. Now!
Kerrigan, a loyal operative, was left to die at the hands of the zerg. / But the zerg had other plans. / They transformed her… and unleashed her psionic power upon the Koprulu sector… / …searching for their real objective… / The protoss homeworld of Aiur.
The protoss were unaware of this danger… and slow to respond. / Their rulers, the Conclave, had dispatched Executor Artanis to hunt for Tassadar… / …a commander who had refused to wipe out infested terran worlds.
They crossed paths with a dark templar mystic, whose kind was considered heretics by the Conclave. / Through great effort, Zeratul convinced Tassadar and Artanis that he was not their enemy. / Together they rallied more protoss from both factions against the zerg. / Despite the Conclave’s fury, they achieved significant victories against the Swarm.
But when Zeratul struck down one of the Overmind’s Cerebrates… / …his own mind was left vulnerable. / From his thoughts, the Overmind gleaned Aiur’s true location… / …and the Swarm descended upon the protoss homeworld… / …with all their might and fry.
It was Tassadar who kept the templar from extinction that day. / Using the power of both the templar and the dark templar… / He sacrificed himself to kill the Overmind.
Aiur was lost. / …but Artanis led the survivors to the dark templar’s homeworld of Shakuras. / Old prejudices were set aside. / The templar were now in the dark templar’s debt.
Without the Overmind, the swarm fractured. / Kerrigan sought control of all the zerg… / …even enlisting the aid of old friends and enemies like Raynor, Mensk, and Zeratul.
Once her rule was uncontested… / The Queen of Blades betrayed them all… / Billions of humans and protoss were killed. / The zerg stood unchallenged, but to the relief of all… / The war seemed to end there.
Zeratul suspected the zerg had fallen under the control of dark forces. / He uncovered prophecies stating that an ancient entity, Amon… / …was attempting to merge protoss and zerg life forms into an unholy hybrid. / And that this evil might already have control… / …of Kerrigan and her power.
It was during this time that Executor Artanis, hailed as a hero… / …was made leader of both the templar and the dark templar. / As Hierarch, Artanis united both factions… / …and promised to one day reclaim the glory they had lost on Aiur.
