Eternia was the
planet that
He-Man and the
Masters of the Universe took place on. Eternia was roughly a roughly
Earth-type planet,
class-M if you will.
Important landmarks:
Castle Greyskull, home of the
Sorceress
Snake Mountain, lair of the evil(and
incompetent)
Skeletor
Castle Eternia,
capital of the
nebulously defined
kingdom that
Prince Adam's father,
King Randor(thanks to
Stride for the name. It completely slipped my
mind.), ruled.
