A small colony world of the New United Nations, the fourth planet in the Gallia binary star system. Since the solar revolution cycle corresponds to rotational period, it is divided into day and night-sides. The Gallia binary star system consists of a large main star and a large companion star and a strong solar wind blows within the system.
At some later point, Gallia 4 became a home to the Zentradi 33rd Marine Fleet commanded by Major Ogotai.
Gallia 4 world was the site of a Dimension Eater detonation in 2059 which destroyed the Zentradi marine battalion, the base and over one-quarter of the planet itself.
