Etheria was founded by a group of beings known only as The First Ones. Their living spirits dwell in the Cavern of Fire, located in an underground kingdom, beneath The Crystal Castle. These beings were spiritual who connected to other planets in which it attracted the spirit of Grayskull of Eternia to unify, creating dimensional portals, where a caravan of Eternians immigrated to this planet, founding Etheria.
When the Horde invaded Eternia, Hordak was defeated by the King of Grayskull, casting Hordak and his allies into the dark field of Etheria, which had a direct passage to the planet, where Hordak takes his possession as the tyrant of the planet, Hordak uses the dark field to Have contact with Skeletor linking his fortress near the serpent mountain, his ancient throne.
The headquarters of the Horde is northwest of The Whispering Woods, where on the Horde's battlefield against rebellion, built its military barracks in the valley of shadows near the dark field "The Fright Zone".
Etheria, the sister planet of Eternia, is ruled by Hordak, a tyrannical leader and member of the Evil Horde.
The Great Rebellion's greatest asset in their battle for freedom is She-Ra, He-Man's twin sister, who was previously a member of the Evil Horde, before defecting.
Etheria has often been linked to Eternia through the use of dimensional portals opened by The Sorceress, are descendants of Eternian immigrant colonist.
At a glance Etheria appears to be a beautiful, lush, fantastical world. But it is plagued by the tyrannical rule of the Evil Horde, which invaded the planet long ago and conquered it.
