Jim Raynor was a Confederate marshal on Mar Sara at the time of the first zerg incursions on that world. Despite bravely fighting the alien aggressors and saving many lives, he was arrested by Confederate forces on the pretext of destroying Confederate property at Backwater Station. When he was subsequently liberated by Arcturus Mengsk’s Sons of Korhal, an anti-Confederate revolutionary group, Raynor chose to fight alongside them.
Zeratul is a dark templar, a renowned psionic warrior and assassin whose forbears were exiled from the protoss homeworld of Aiur over a thousand years ago. The dark templar refused to submerge themselves in the communal protoss mind link, the Khala, preferring instead to strive as individuals. Zeratul holds the rank of prelate and is probably best known for his role in ensuring the survival of the protoss since the zerg threat first became apparent.
No single human being has been more inseparably tied to the twisted destinies of the terran, protoss, and zerg races than Sarah Kerrigan.Potent psionic abilities, unmatched courage, sharp tactical instincts, and lethal training in both melee combat and ballistic weaponry led to Kerrigan’s quick rise through the ranks of the Confederate ghost program.
