He-Man: Power of Grayskull

Eternia was once a place of beauty and safety. Protected by the Masters of the Universe and the Mystic Wall, this sacred land could never be touched by the evil of the outside world. But one dark day Skeletor and his evil warriors were able to breach the Mystic Wall. Their relentless attacks have pushed the Masters of the Universe to their edge-and now, yet another wave of attacks. (igdb)
