Satria Power Stones

"Power Stones" are the source of power of the VUDO Empire. With unknown origins, Powerstones possess a latent force that can interact with their owners through a "Changer", giving their owner the power of a "Satria", the legendary hero who protects the Earth from time to time. The seven Power Stones have been contested by the rulers VUDO, either by Rasputin or the Black Lord in VUDO's invasion mission to Earth.
