The Sorceress traces Orko’s magic to the strange world of Omiros, and He-Man and Orko journey there to recover the magic. On this surreal planet, they find that an evil wizard called Zolt has absorbed Orko’s magic and is using it to control Omiros. They must fight Zolt and recover Orko’s magic before the portal back to Eternia closes!
