The Energy Crystals are a large set of crystals on Liotyr. When infused with gemstones, they have the power to create living Gems. They were first used by Gem and Jewel to create Ruby. Gem and Jewel created more Gems until 185,000 BCE. Ruby created the new Gems annually until 2089 BCE, when the planet was corrupted. The last Gem created by them was Pearl.
