Antioch was a protoss province located on the world of Aiur, featuring a base seemingly of the same name. It was the location of the Citadel of the Executor. Judging by maps of the area, Antioch was situated in the southwest corner of a valley alongside a river.
The zerg invasion of Aiur devastated the planet and Antioch was no exception, experiencing numerous zerg attacks. Two days after the invasion's conclusion proper (the manifestation of the Overmind), the outpost, under the command of Praetor Fenix, was on the edge of the abyss in terms of manpower and resources. As such, the Conclave ordered that Antioch be reinforced, as the first priority of the protoss forces was to strengthen their defenses.
First Battle of AntiochEdit
Reinforcements under the leadership of a new executor, Artanis, arrived at Antioch, having successfully engaged numerous zerg patrols in the lands surrounding it. Fortifying the base, the protoss then launched a successful counterattack against the zerg Tiamat Brood forces which occupied the ridge to the north.
Second Battle of AntiochEdit
While the protoss forces carried out an attack on the zerg-held province of Scion, Antioch fell under attack by overwhelming zerg forces. The defense was not nearly as successful as the first battle, and Fenix was mortally wounded.
By the end of the war, Antioch had been reduced to a wasteland.
It shares the name with an ancient Greek city.
