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.
The Sorceress sends Adam to Etheria as He-Man is needed to aid She-Ra in defending the villagers of Dryl who are forced to work the Etherium mines for the Evil Horde.
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.
