Zaria, a terrestrial planet, existed within the Zaria system, situated in the Juvex sector. This sector was a component of the Senex-Juvex region, which itself was located in the Western Reaches area of the Mid Rim. The Senex-Juvex Loop hyperlane provided a connection between Zaria and the Anstares and Malador systems.
As an industrial planet, Zaria served as the original home of the Zarian species, a group of intelligent, frog-like beings. Despite the Zarians' freedom, their planet, along with the other Senex-Juvex worlds, remained under the dominion of the Ancient Houses, the aristocratic rulers of the region.
