Sir Balen was squire who pretended to be a knight from King Arthur's Court. After "borrowing" his master's armor and sword while he's asleep, Balen set out into the moors and was enshrouded in a "blue bubbling fog" and ended up in the Land of the Lost just in time to save Christa from a gang of Sleestaks. After Shung heard of this, he sent Keeg and Nim after Balen's sword, thinking it to be a "magic blade".
