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.
Modulok has built a rocket specifically to disrupt the gateway between Etheria and Eternia that She-Ra and He-Man use. Adora ends up a thousand years in Eternia's past. There she meets Granamyr the dragon and his alley, Tarben.
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.
