According to the legend there are 13 Ancient Crystal Skulls made by beings not from this planet. When they are aligned they will open a portal to other realities. Some believe this has to do with Mayan calendar — which comes to end on Dec. 21, 2012.All modern Crystal Skulls are portals to the ancient ones. I became the caretaker of the 67 lbs Quartz Crystal Skull called STAR SIRIUS on July 23 2006 which is one of the largest crystal skulls. Star Sirius is a spiritual shortwave, when you put both of your hands on the skull you make a circuit it is giving you information and you are giving it information too.
