This story centres on the canonical theme of the combined halves of the Power Sword allowing access to Castle Grayskull. After diverting the Heroic Warriors to Point Dread (which isn't actually seen in the illustrations), Mer‑Man is able to capture He‑Man and take his sword to Skeletor. He‑Man survives the attempt to drown him, and is then given a special power to enter the castle when Zodac makes a brief appearance. Unsurprisingly, Skeletor loses the subsequent battle. There's a forlorn note at the end when He‑Man admits more trouble lies ahead.
