Wiki Grayskull

Etheria the brother planet of Eternia, is ruled by Hordak, a leader and member of the Horde of Evil.

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, and its people are descendants of Eternian immigrant colonists.

At a glance Etheria appears to be a beautiful, lush, fantastical world. And while this is indeed true, in reality, it is also a dystopia plagued by the tyrannical rule of the Evil Horde, which invaded the planet long ago and conquered it. However, due to the continued efforts of The Great Rebellion, the planet is slowly but surely becoming more and more liberated.


Main article: Timeline of Etheria

Etheria was founded by a group of beings known only as The First Ones.[1] Their living spirits dwell in the Cavern of Fire, located in an underground kingdom, beneath The Crystal Castle.[2] These beings were spiritual who connected the planet brother Eternia and other planets in which it attracted the spirit of Grayskull, Light Hope, (former member of the guardians of Castle 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.

About 300 years ago, Eternia and Etheria had a world war for dimensional demons, both planets had large advanced cities, but powerful parts like Grayskull Castle and Crystal Castle were preserved in the war. Ancient archaeological cities in medieval style have been used and refined to new technologies, as in the case of the Royal Palace of King Randor. In Etheria, the ruins of large cities, gave rise to the construction of colonies and royal palaces.

Years later, this connection of the portals opened a dangerous dimension, releasing the pernicious Gargh demons that invaded Etheria and Eternia, starting a world war on the two planets, the demons dominated the portals and destroyed the connections of various worlds, preserving only the connection between Eternia and Etheria, resulting in the colonization of Eternian survivors for Etheria after war. Only Trolla has preserved part of the remaining portals against the Gargh, one of them goes towards Earth
