Once upon a time Nicholas St. North married the love of his life, the woman we all know as Mrs. Claus. After the two founded the North Pole and became holiday spirits they had two daughters, the younger being Shiva, who both inherited their father's powers over winter. One day the beautiful winter spirit met the angel of the Night and the two fell in love and had Jack and Millie Frost. :) #riseofthetguardians #finalfantasy
