Hordak and Octavia journey to the Sea of Sigh to witness the rising of the legendary Mystic Isle, an island which will emerge from beneath the ocean but once. They plan to steal its treasures left by the First Ones, Etheria’s founders, and use them for Horde purposes. She-Ra and Sea Hawk are the only ones who could possibly stop them – but can they get to the Isle before the Horde do?
