While attempting to master a new spell, Orko inadvertently has his magic snatched away by a tiny creature known as a Gronk, which then vanishes to another realm. The Sorceress manages to track Orko's lost magic to the bizarre world of Omiros, prompting He-Man and Orko to embark on a quest to retrieve it. Upon their arrival in this strange land, they discover that a malevolent wizard named Zolt has absorbed Orko's powers and is using them to dominate Omiros. They must confront Zolt and reclaim Orko's magic before the gateway back to Eternia shuts for good!
