Eternia™ has everything: laser tanks, magic castles, extremely confident skeletons, and one very reasonable solution to most problems—raising a sword into the sky and shouting with purpose.

When evil gets ambitious, things tend to move quickly. Lightning cracks. Courage flexes. The most powerful man in the universe arrives with the calm certainty of someone who knows that friendship, honor, and a very large sword can solve an impressive number of problems. Orko’s magic makes the battle stranger, Man-At-Arms makes sure it stays winnable, and Skeletor™ somehow remains shocked when the Power of Grayskull™ ruins another perfectly dramatic scheme.
