A year later, Rau's rival Imperial Viceroy Gar Saxon and his Imperial Super Commandos launched an attack on the Protectors Camp in an effort to lure Rau out of hiding. Saxon had learnt about the Protectors' collaboration with the rebels and slaughtered Rau's followers. Rau, Sabine, and her fellow rebels Ezra Bridger and Chopper returned to the moon to investigate. After joining forces to escape Saxon, Rau decided to join the rebellion.
