Having been convinced by his friend Raaba that Humans had never atoned for their atrocities committed under the New Order, the Wookiee Lowbacca goes to Ryloth to join the anti-Human Diversity Alliance.
Meanwhile, at the Jedi Praxeum, his fellow Jedi trainees Jacen, Jaina, Raynar Thul and Tenel Ka travel to Ryloth to discover the Diversity Alliance's true purpose. There, they discover that the Diversity Alliance is preparing to launch a war on the Human species in retaliation for the crimes of the Humanocentric Galactic Empire. However, they get captured and are sent to work in the ryll mines. Lowbacca had never been told about their presence though when he found out, the Wookiee turned against the Diversity Alliance and helped them to escape the planet. But will they be able to convince the New Republic to take action against the Diversity Alliance?
