The planet Mimban, formally known as Circarpous V, was located in the Circarpous sector of the galaxy’s Expansion Region, in grid square O-12 on the Standard Galactic Grid. Located in a remote star system, it was situated along the Nanth’ri Trade Route between the worlds Kerev Doi and Batuv. It had a dense, ionized atmosphere whose thunderstorms made the planet’s sky perpetually overcast, while its marshlands were always draped in mist.

A humid world, Mimban’s surface was covered in rainforests and swamps. The planet possessed valuable minerals, including deep hyperbaride deposits. The climate began to be devastated from the Confederacy of Independent Systems’s indiscriminate mining practices, with a great deal of mud beginning to form on world during the Clone Wars. Mining by the Galactic Empire during the Imperial Era continued to devastate Mimban’s climate.
