Solar Signs

Once every five hundred years all of the Zodiacs come to Earth for four days to mate with a mortal of their choosing. Once their four days are up, they return to their rightful place in the sky. From up in the sky the Zodiacs watch over their children, and when they turn twenty-five the children of the Zodiacs will join their celestial parent in the sky. Sadly, since the children of the Zodiac are only part celestial beings, they die and become shooting stars.
