Koprulu Sector - Mar Sara

Mar Sara was a core colony of the Terran Confederacy and the setting of the first missions in StarCraft. As at Chau Sara the Zerg began infesting the planet by seeding its atmosphere with their spores. However when the Protoss arrived to cleanse Mar Sara they held off attacking; the Confederacy had mounted a clumsy counter-attack to protect the planet from them, and Executor Tassadar did not wish to kill any more Terrans than was necessary. Instead of attempting to rescue the population from imminent destruction, though, Confederate forces concentrated on evacuating their own equipment and personnel from the planet.

This created a perfect propaganda opportunity for the Sons of Korhal, who arrived with transports to save as many civilians as they could. They were thus able to gain the loyalty of the local Colonial Magistrate and Marshall James Raynor, both of whom joined the rebels. The Sons of Korhal were also able to break into the Jacobs Installation and discovered that the Confederacy was responsible for the Zerg attack, having created psi emitters to lure them to the planet. The rebels managed to escape Mar Sara just before the Protoss eradicated all life on the planet. According to the official website for StarCraft II, the Zerg were believed to have recolonized Mar Sara following the Protoss sterilization. The website also reveals Mar Sara has two moons, Pyramus and Thisby (named after the two lovers of Shakespeare's play within the play A Midsummer Night's Dream).
