The first season revolves around the efforts of Graveheart, who has become the de facto leader of the Alliance, to convince the leaders of the other Cluster worlds to join the Alliance. The first planet they visit is his home planet, Planet Rock, but Lord Mantel stubbornly refuses to ally himself with the other worlds after Rock's Battle Moons repel a Beast attack. Graveheart's friend and captain of the Royal Guard, Jade, joins him to help rally planets Fire and Bone to his cause. Fire and Bone join the Alliance.
