Original Airdate: ?/?/1984
When Adam, Man-At-Arms, and Orko find a map to the ancient Stone City, where a treasure is buried, Evil-Lyn steals it from them. She, Webstor, and Kobra Khan go to the city, where stone statues stand everywhere. Evil-Lyn transports an object later revealed to be the Life Bringer to her laboratory in Snake Mountain. A shaft of sunlight revives Vulcan from his statue form.
The ruler of Stone City reveals that his people chose to sleep for hundreds of years because their warrior specialties were not needed in times of peace; so they hoped the Life Bringer would revive them when their services could be better used. Discovering the Life Bringer missing, Vulcan blames the villains, but Evil-Lyn says He-Man took it. She brings Vulcan to Grayskull pretending that the Life Bringer is inside. He-Man stops Vulcan from entering Grayskull, and both team up to assault Snake Mountain. Skeletor caves in and drops the Life Bringer to them.
They miss the pivotal moment when the Life Bringer and the moon are in perfect alignment, thus He-Man moves the mountain supporting the Life Bringer, allowing the moonlight to energize the machine and revive all the people of Stone City. Back at Snake Mountain, Skeletor punishes Evil-Lyn and Webstor by making them carve a giant stone statue of him.
