Dinube was a member of the Harch species and held the rank of Elder within the Path of the Open Hand cult. He was present at the Path compound located on Dalna both before and during the infamous Night of Sorrow, which transpired in 382 BBY. Following the illness of the Path's leader, known as the Mother, Elder Jichora summoned Dinube, who then diagnosed the Mother as having suffered a seizure.
Subsequently, Yana Ro came across Dinube in the adjacent town of Ferdan. He was standing atop a koyo-fruit crate, publicly scolding individuals for neglecting what the Path perceived to be the suffering of the Force. Yana had earlier viewed Dinube as a more reasonable figure within the Path community, but she now perceived this conduct as merely one indication of the evolving doctrines and practices of the Path. Returning to the Path's underground cavern network, Yana discovered Dinube inspecting detonite explosives, which the Elder asserted were meant to facilitate the excavation of additional caverns for the Path's purposes.
