The Jewel of Protection is an artifact featured in He-Man and the Masters of the Universe. The Jewel of Protection had been left under the protection of the inhabitants of Chandor Village by the legendary Gryphon two hundred years before the time of He-Man. During this time it was kept in the so called Shrine of the Gryphon.
Village elder Galen knew that if anything happened to the Jewel, the Gryphon would swiftly return to the village and curse it. When Trap Jaw and Beast Man snuck into the village and broke into the shrine to take the Jewel, the curse of the Gryphon soon proved to be more than just a legend.
The Evil Warriors hid the Jewel in the gardens of the Filmation in nearby Eternos, where it was found by a young page named Thad. After several adventures, the jewel fell into a river and began to hatch. It turned out to have contained a Baby Gryphon for all these years. Both the baby and it's parents were afraid of the water, but brave Thad took it upon himself to dive into the water and reuinte the two Gryphons, who happely departed shortly afterwards.
