Eternal Darkness

Eternal Darkness is the 46th episode of He-Man and the Masters of the Universe, written by Misty Stewart and directed by Lou Kachivas. A series of nightmares in the Royal Palace reveals that Darkdream has escaped from his prison, and He-Man must stop him from darkening Eternia with a permanent solar eclipse.

Moral
Teela: "In today's story, I had a bad dream. You know, bad dreams or nightmares happen to everyone. and they can seem pretty real. But they aren't. They're no more real than any make-believe story or fairy tale. So don't be ashamed or afraid of telling anybody about your dreams. It happens to all of us. And like so many other things, talking it over with your mother or your father, or maybe even a good friend, can make you feel a whole lot better. Bye for now, and... pleasant dreams!"

Behind the Scenes

 * Script was approved May 5, 1983 and final script revision took place June 22, 1983.
 * The story was loosely based on an early Filmation script premise called "Eclipse on Eternia" which featured Skeltor creating an eclipse, forcing He-Man to rearrange the planets.

Continuity

 * This is the first time Teela is seen without her tiara. The second will occur in The Witch and the Warrior.
 * The animation of Orko after Man-At-Arms compliments his hearing is reused from the scene in Disappearing Act shortly before he and Cringer enter the Time Corridor.
 * When Prince Adam and Teela run through the Palace to their Sky-Sleds, the Photon Cannon weapons from Reign of the Monster can be seen in the background.
 * The Royal Palace courtyard where He-Man and Teela jump onto their Sky-Sleds to go to the Crimson Valley. was first seen in A Friend in Need when Jarvan re-materializes there.
 * The Sorceress transforms into Zoar in front of Stratos, revealing he know her secret identity as the falcon.

Errors

 * In this story and in Jacob and the Widgets, it is stated that Eternia has only one moon. But in The Shadow of Skeletor, Into the Abyss and the She-Ra: Princess of Power episode He Ain't Heavy there are more than one.
