Four thousand six hundred years ago, an ancient civilization known as the "Star People" faced the threat of annihilation by "Silent Pollution," a force of nothingness capable of devouring memories, history, and civilization itself. On the salt flats of Ur, seven Mark-Bearers put the entire existence of their civilization on the line and "borrowed" a four-thousand-six-hundred-year reprieve from the "Cradle Protocol" System. This was no rescue. It was a predatory loan, a promissory note. Now that note is coming due.
