Sarah Louise Kerrigan discovered her psychic gift when she was a little girl. Once, she played childish with her parents, and as a result, her mother's brain blood vessel exploded and she died. In the next few years, her father will only repeat one sentence: "I saw her head cracked." This frightening event made the Tyrone Federation aware of her energy, and soon she became the focus of the ghost project. Because she got an unprecedented score in the psychological evaluation. Even this grading system must be readjusted to accurately measure her ability. Kerrigan's only humanity was thus taken away. Her ghost number is 2460 1.
She did very well in the Ghost Project and became an invincible assassin against the corrupt federal government. During the assassination of independent MP Angus Monske, Kerrigan noticed Angus' ambitious son, Ake tours. At first, tours intended to kill Kerrigan to avenge his father, but later he found that it was obviously more appropriate to use her against the Federation. Therefore, after rescuing her from the secret experimental facility, he removed the neural controller from Kerrigan, restored her memory and made her angry with the federal government that tortured her. Kerrigan and Munsk became allies.
Kerrigan met Jim Reynolds for the first time. He was a former federal sheriff and just joined Keha's son. He didn't appreciate her deadly way to the Federation, but they didn't know each other, and soon this feeling became mutual respect, admiration and even ... more. Before Monske moved the "revolutionary step" to Tasannis, Kerrigan and Renault carried out several secret missions together. Ak tours plans to use psionic launchers to induce alien insects to attack the most densely populated planet in the region to destroy the Federation, which shocked cold-blooded people like Kerrigan. Tasannis will be ruined by this. Although she opposed it, she faithfully carried out the task of protecting the main nest from the mysterious new racial spirit. Monske took advantage of her loyalty, and when the task was completed, she abandoned Kerrigan to him regardless of his life. He thinks that people like Kerrigan are a threat to the new government, and he also understands their long-standing hatred of revenge.
To Monske's surprise, this move made alien bugs his enemy.
The alien master realized Kerrigan's outstanding powers and wanted her to be a new weapon for alien insects. The master implanted all excellent and powerful genes into the former ghost warrior, and turned Sarah Kerrigan into an unstoppable psionic monster: the Queen of Blade was born.
In order to keep Kerrigan's own intelligence and strategic talent, the host did not assimilate her with other aliens. This freedom gave birth to her ambition. Soon, she conquered the brain worm, and then her rule was eliminated in Ayr, and Kerrigan became the new leader of the worm group.
Now, no one knows where the Zerg in Kerrigan are going. Ancient prophecies have revealed her future. These predictions are so obscure, but accurate: hundreds of millions of creatures will be linked to the fate of Sarah Kerrigan.
