Skeletor and Evil-Lyn invade the Temple of The Fire People in order to get possession of the Spellstone. Evil-Lyn uses the Spellstone to cause fierce storms and create great upheaval on Eternia. He-Man, Battle Cat, Stratos and Ram Man battle Skeletor and his Hover Robots at the temple, but are trapped underground. At the Royal Palace Evil-Lyn, in disguise, fools some nearby villagers into giving her possession of the Creeping Horak, which in turn she uses to trap the king and queen, Man-At-Arms, Teela and Orko. After fighting the Fire People, He-Man and the others head back to the Palace, and find Skeletor, Evil-Lyn and Trap Jaw. The Creeping Horak has nearly enveloped the entire Royal Palace, but He-Man manages to retrieve the Spellstone and use it to destroy the Creeping Horak, saving his friends. Skeletor escapes and the Spellstone is sent back to the Temple of The Fire People.
