- c. 1502: An ancestor of Kal-El's comes to Earth with several radioactive rocks from the planet Krypton. He falls in love with a Native American woman, thereby fathering the Kawatche people. This prophetic Kryptonian forges the prophecies in the Kawatche Caves, hiding several "parasites" from his homeworld within the cave walls and burying the Starblade so that it will take at least 500 years to recover it. Knowing that his destiny did not lay on Earth with the first of the Kawatche, Kal-El's ancestor bids them farewell, promising he (or rather his descendant, "Naman") would return to protect them all again. He then flies off, hides the sacred Stones of Power all around the Earth while building the reputation of a mighty "god" along the way, before leaving for Krypton once and for all, swearing to the natives of China that he would return for what is his one day.
