Clamp Champ, Adam, and the Sorceress arrive at Eternia Tower at
midnight. The purpose: to find out what happened to Randor's lost
brother Keldor (Skeletor: "They must never discover the secret
of Keldor, for that knowledge could destroy me!") So he sends
Ninjor and Scare Glow, from Eternia's history and future, to stop
them. They can't, and Skeletor ends up melting away into nothingness
in the jaws of the Eternia Tower later after He-Man throws him there.
