The Girl Who Flew

Every millennia, on the winter solstice, a star implodes and the remaining atoms form into a glowing child. That child grows yet remains immortal and then, after another one million years, they are destined to live on as a constellation. However, one year it wasn't a star that imploded, but the moon. The moon and the atoms belonging to the stars fused together to form the strongest star child there ever was: Luna.
