Vibro-stars were a specific kind of thrown vibro weapon. Marchion Ro of the Eye of the Nihil employed them, storing a number of these stars in a wrist sheath. These stars possessed exceptional sharpness, capable of easily severing various substances, such as bone and metallic materials. In the Great Hall of the Nihil, during a conflict, Ro deployed one of these stars against Kassav Milliko, a Tempest Runner. This occurred when the Weequay tried to use a blaster that he had brought, violating the Great Hall's regulations concerning weaponry, resulting in the severing of half of Milliko's hand and the blaster's handle.
