Thousands of years ago, thirteen crystal heads were scattered across the earth – and they are greater and more powerful than anything we have the ability to manufacture today. Their workmanship is perfect: they contain no tool marks and have been cut against the natural axis of the crystal, defying the laws of physics. Some say they are artifacts from the lost civilization of Atlantis, some say they date back to the Mayans, still others say they were created by a higher intelligence.
Brought together, the Crystal Heads are said to contain vast knowledge and enlightenment capable of unlocking our most enigmatic ancient mysteries. Alone, each is believed to house radiant psychic energy, which has magical powers and healing properties
