The Diamals were a white-maned race of sentients native to a planet of the same name. They were involved in a minor shipping security dispute with the Ishori, shortly before the Caamas Incident. The Diamals didn't trust the Ishori patrol ships which escorted Diamalan transports into Ishori ports. Han Solo and Luke Skywalker tried to resolve the conflict, but were unable to do so. Instead, the dispute grew into a large-scale political battle with the revelations of the Bothawuian involvement in the destruction of Caamas. The Diamal Senators firmly believed in the "forgive and forget" solution to the problem, while the Ishori wanted justice to take more physical form. They were a very honorable race, and respected the heroes of the Galactic Civil War. They were also very stoic, often described as unemotional.
