The true origin of the Sha'Kurians is not known except from what Klingon Imperial Intelligence has managed to gather. What is known is that they are an old race, one that does not have its origins within the Beta Quadrant but are in fact native to the Delta Quadrant. At some point, the Sha'Kurians went on an incursion outside their territory to attack a Romulan outpost on the border. During this raid, the Ducal Territories managed to incorporate Gorn Graviton Density Distortion Sphere Generator technology into their ships.
