In the distant past, the Guardian of the Milky Way galaxy named Lanancuras began to harbor a desire for more power. Because of his connection to the galaxy, he was able to absorb parts of planets and add them to his strength. As a result, he began invading the worlds he was assigned to protect. In the wake of his destruction, a following of creatures from across the galaxy pledged allegiance to Lanancuras and became known as the Kadrians. Taking notice of his ever-growing power and followers, the other Celestial Guardians confronted him; however, he had become too powerful, and they were defeated. Unable to subdue Lanancuras, the Celestial Guardians each gave up a part of their power and combined it into a single new Guardian, Mushra. In a final desperate attempt, they used Mushra's core by transforming it into a powerful card with which to seal Lanancuras in a prison. The prison was created from the remains of planets that had suffered under Lanancuras' tyranny. Because planets are themselves large beings, their combined strength- along with the power of the card- was able to restrain him. Thus Lanancuras was successfully sealed in a large meteorite.
