Barely escaping the Nexus with their lives, the Defenders set out for the Pinnacle, an ancient Di-Gata training temple. On the way, they face the Obelisks, an army of war machines created for Nazmul by Flinch. Erik and Kara stay behind to try to stop the destruction while Seth and Mel head for the Pinnacle to hopefully cure Mel of her wizard attacks. At the Pinnacle, Seth must face Omniaxor, his father’s Guardian. When Seth brings out his guardian, Kragus, Omniaxor takes him by the arms and breaks him into little pieces. Seth then realizes that Kragus' stone never came back, therefore he has been destroyed. In this episode, Melosa completes her Wizard of Yan training and for the first time, uses her wizard powers, in which she has full control over.
