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.
He-Man and She-Ra rescue Glimmer's mother, Queen Angella, from the harpies. Convinced that Etheria is in good hands for a time, Adora decides to leave with Adam to visit their parents. Hordak follows.
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.
