S01E01 Into Etheria
Sorceress discovers a gateway to another world. She sends Prince Adam and Cringer in to investigate. They find the new world to be enslaved by Hordak and his second in command, Adora.
Hordak and Skeletor kidnap Adora. After she escapes, as She-Ra, she realizes that being back on Eternia is dangerous for her family. She returns to Etheria, with He-Man, just as the Rebels get ready to claim the kingdom of Bright Moon.
She-Ra, He-Man's twin sister, is leading a group of freedom fighters known as the Great Rebellion in the hope of freeing their homeworld of Etheria from the tyrannical rule of Hordak and the Evil Horde.
