Antares IV is the fourth planet in the Antares star system. It is the sight of a human colony with a population 6 Billion. The planet used to belong to the Iconians and was the home to an old Iconian Tomb. The Ceti Squad were sent there in order to see in Kilgraths brother would be there. But, he wasn't.
According to the Avalon 9 Antique Books, Iconians where a mythological creation by the Qualizian Domain to preseve the surface of the planet intact during the Third War of Truth. The tomb then might have been one of the primitive monoliths in which the cult to the Sun and to Grux was originally developed before minners colonies in outer Antares system where set up.
