The day twins were born to one of the lesser constellations was the day that E. Aster Bunnymund realized that one of them was meant to become the Spirit of Winter and Guardian of Fun years into the future of the planet known as Earth, having met the boy himself after becoming the Guardian of Hope and Spirit or Easter, and told the parents of the twins so which allowed him to take the younger of the two through space and time to where he needed to be.

It took him a while but Aster was able to find the place he was supposed to be and family he was meant to be raised by thus Jackson Overland Frost was born with all memory of him being erased from the past. As the boy grew, with no idea of whom he really was, Aster made sure to keep a close eye on him so he didn't come to any danger before it was time for him to become the Spirit of Winter and fulfill his destiny as the Guardian of Fun.
