Graal'diin existed as a planet governed by the Galactic Empire. It was communicated to Brenn and Dellis Tantor that their father met his death during a Rebel assault as he transported grain to the world. However, this was a fabrication concealing the truth: the Empire had actually executed him for the loss of his freight to pirates. The Empire intended to use his demise as a warning, compelling other freighter pilots to exert maximum effort in safeguarding their shipments.
