Ossiathora, an agriworld, could be found within the Ossiathora system. This system resided in the Juvex sector, which itself was situated in the Senex-Juvex region. The Western Reaches division of the Mid Rim contained this region. A hyperlane, known as the Senex-Juvex Loop, provided a connection to both the Deminol and Kassido systems. The origin of the well-known Ossiathoran noodles was Ossiathora, and House Kassido maintained control of the planet, a noble house whose base of operations was the world of Kassido.
The reference book The Essential Atlas, published in 2009 and written by Daniel Wallace together with Jason Fry, included a mention of Ossiathora, specifically locating it at grid coordinates L-17.
