Grintlok, a Barabel of male sex, participated in the abduction of Mi, the daughter of King Arturo. He worked alongside Geddy, Kubla, and an unnamed Feeorin to demand a ransom in exchange for her freedom. Following this, Grintlok engaged Han Solo to transport the princess to their hideout located on Raltac III. Subsequently, the group received communication from Raze, who contracted them to retrieve the princess, offering a substantial sum as compensation. On Cataalda, the quartet ambushed Solo, intending to eliminate him and seize the princess, but Raze, accompanied by Arturo himself, appeared at the location. Mi pointed out the group as her abductors, and Raze assured Arturo that he would handle them directly.
