New Brigia existed as a planetary body within the Koornacht Cluster, as a planet.
Around two years prior to the Battle of Yavin, a small band of Brigians hailing from Brigia established a colony on New Brigia. Their primary purpose was the initiation of a chromite mining venture.
During the period known as the Great Purge, the entire population of New Brigia was exterminated by the Yevetha. Of the thirteen alien settlements within the cluster targeted by the Yevetha, New Brigia was the smallest.
The landscape was marked by numerous excavations and pits created for the purpose of chromite extraction. Upon seizing control of the planet, the Yevetha plundered substantial quantities of the metal from the storage facilities. Only following their departure from the planet's surface did the Yevetha unleash a devastating barrage into the valleys, causing complete vaporization and sterilization of all matter within them.
