A chess-playing nobleman called Lord Todd, from a far-off land, visits Palace Eternia and instantly charms and astounds the Royal Family with the wonderful gifts he provides them, and his incredible skill at chess.

However, things turn disturbing when Man-At-Arms is called to Grayskull by The Sorceress, who tells him that a great evil has arrived on Eternia from another dimension... and it has taken its base nowhere other than Castle Star.....
