In the fictional StarCraft universe, the Gantrithor was once the Protoss command ship and under the command of the former executor Tassadar. The Gantrithor was Tassadars personel carrier, and was destroyed when Tassadar set the ship on a collision course with the Zerg Overmind and destroyed it. Tassadar perished in this crash but in the end saved Aiur by destroying the Zerg Overmind. However, even though the Overmind was destroyed, the surviving Zerg forces without any instructions began their rampage across Aiur. In the midst of this chaos, the last surviving Protoss relocated to Shakuras, the world of the Dark Templar.
