Dark Hemisphere

The Dark Hemisphere, along with the Light Hemisphere, make up the two halves of Eternia. The Dark Hemisphere is used to describe any portion of the planet Eternia not under at least the nominal rule of the legitimate government of Eternia. During the time of the Great Wars centuries ago, the term Dark Hemisphere referred to those portions of the world controlled by King Hiss's Snake Men or Hordak's Evil Horde.

More recently, the term Dark Hemisphere referred to the portions of Eternia controlled by Skeletor, either in alliance with Hordak's Horde or with the aid of Skeletor's own Evil Warriors, Hover Robots, and other minions.

In the 2002 series, it was established that the Light and Dark Hemispheres were created when Hordak and his sorcerers used an artifact called the triad to cast the spell of separation. Hordak used the spell to separate the planet into two hemispheres, light and dark. However, the planet itself, began to separate and, realizing he was in jeopardy, Hordak ceased the spell and sent the three parts of the Triad to the corners of Eternia.
