When a new member joined the ranks of Rav's crew, they were branded with the symbol of the Bloody Bones and compelled to recite his vow. Individuals like Cade Skywalker and Jariah Syn were obligated to pledge their allegiance to Rav. However, around 137 ABY, during their acquisition of the Grinning Liar, Cade made Rav take the oath to him, only for Rav to subsequently betray him by swearing it to Darth Maladi.
