Char Aleph

Char Aleph is a space platform situated in near orbit over the planet Char. It has been infested by the Zerg.

History
In the aftermath of the Guild Wars, the Terran Confederacy gained control over Char. The few personnel that would operated the mining sites were to reside in Char Aleph. However, when the Zerg invaded a decade later, the space platform was overrun and infested, serving the Zerg as an orbital nesting site and hatchery.

During the Brood War, Char Aleph served as Kerrigan's base of operations for a time, where she would plan the downfall of the Overmind. It was also at Char Aleph that the final battle of the Brood War would be played out, the fleets of the Protoss, Terran Dominion and United Earth Directorate Expeditionary Force falling to the Zerg.

Trivia
Char Aleph is likely derived from the Codex Sinaiticus, a 4th century uncial Greek manuscript of the Bible. Aleph is a shorthand designation for it.
