The Rapacc system, a celestial body classified as a star system, was situated within the enigmatic Unknown Regions. This box system was the home of the planet known as Rapacc, which served as the original homeworld for the Paccosh species.
Being a box system, the Rapacc system presented significant dangers to spacecraft attempting to transition into or out of hyperspace. This was due to exceptionally powerful electromagnetic fluxes, which amplified the risks beyond those typically found in The Chaos. Furthermore, an ancient cataclysm, occurring millennia prior to the initial visit of the Chiss, resulted in the widespread distribution of meteors throughout the system, thereby complicating navigation within its boundaries.
