Supreme

Sarah Kerrigan intended to unite all the packs of Zerus. She gained the assistance of Dehaka and Zurvan the Ancient One in her quest.

She defeated pack leaders Yagdra, Kraith and Slivan in turn, when Zurvan turned against her. She eventually defeated him too, taking command of the primal zerg.

Aftermath
Upon Kerrigan's return to the Koprulu Sector, she received a communication from Arcturus Mengsk. He declared that Raynor was in fact alive, but would be executed if Kerrigan brought her Swarm anywhere near him.
