Char is an unstable volcanic ashworld that supports little native life. It was colonized by the Zerg during the events of the first game, to act as a safe birthing ground for the transformation of Sarah Kerrigan into the Zerg's Queen of Blades. There were several battles on the surface of Char between the Zerg, Protoss and Terrans. The fighting continued until the Zerg Overmind discovered the location of Aiur with Zeratul's assassination of Zasz. Thereafter the Overmind left Kerrigan behind on Char to deal with the remaining enemy forces while it traveled to the Protoss homeworld.
During the events of the StarCraft: Brood War Char again came into focus as the new home of the reborn Overmind. The United Earth Directorate succeeded in invading Char and capturing the Overmind for their use, but were subsequently driven off and the Overmind was killed by Kerrigan, who assumed command of the entire Zerg Swarm. Char is still under Zerg control at the time of StarCraft II: Wings of Liberty and remains their primary base of operations.
