Gems of Cronus

The Gems of Cronus were three powerful jewels created by the ruler of the Titans, Cronus. Each Gem gave Cronus a power and he placed each into a piece of armor; one in his helmet and two in his guantlets. With these gems, Cronus could control all of reality and bend it to his will. Due to this great power, Cronus went mad with paranoia and power, nearly destroying everything had it not been for his son Zeus defeating him. He was then stripped of the Gems and they were cast down to Earth to keep them out of the hands of his mad father.
