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.
Shadow Weaver is insulted by Hordak and seeks an alliance with Skeletor so she can rule Etheria herself. But of course Skeletor has no intention of keeping up his part of the bargain.
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.
