Colunda Prime was a celestial body situated within the Colunda Prime system. It was a component of the Colunda sector, itself a subsector of the Phelleem sector located within the Slice region of the Outer Rim Territories. Char Bibbeck, a Senator representing a sector within the Galactic Republic's Senate, originated from Colunda Prime.
In the year leading up to 13:4:11 on the date, Bibbeck and fellow Senator Jonas Wallen of Darlon, a Mid Rim planet, were betting on the probability of certain planets either seceding from, or remaining within, the Republic. This gambling was later exposed, and on 13:4:11 it was reported from Basbik, Colunda Prime in an edition of the HoloNet News called the CoCo District Edition.
HoloNet News Vol. 531 #51, an in-universe issue of the HoloNet News penned by Pablo Hidalgo and Paul Ens and released on the HoloNet News website on April 11, 2002, introduced Colunda Prime. The Essential Atlas, a reference book from 2009, situated the Colunda Prime system, and consequently the planet itself, within grid square S-7.
