The Gopso'o constituted a Nim Drovis based tribe of Drovians. Despite appearing almost indistinguishable from the Drovians, their adversarial tribe, they had been engaged in war for a period exceeding the collective memory of both groups. According to a Drovian individual interviewed by Ism Oolos, the Gopso'o apparently derived pleasure from the act of murdering innocent relatives of their Drovian adversaries. Subsequent to the Death Seed epidemic, the New Jedi Order facilitated a peaceful agreement between the Gopso'o and the Drovians.
