The conflict known as the Nim Drovis Civil War took place between the two primary tribal groups inhabiting Nim Drovis: the Drovians and the Gopso'o. The specific reasons that triggered the war have been obscured by the passage of time. However, some accounts suggest that it began with a disagreement regarding the grammatical form of the Drovian term for "truth," with one faction arguing for a singular interpretation and the opposing faction for a plural one.
