The First
She was the first it made. They spent a lot of time together before it made the rest of it's family.
It taught her an small portion of it's infinite magics and eventually stopped a bit after the accident(where she blew all her limbs off experimenting alone).
She eventually taught the rest of the Divine Powers simple and complex magic to take care of their assignments of the earth.
She was most devastated out of them all when it left. The relationship between them wasn't clear to the rest of the Divine Powers,
father and daughter, student and teacher or wife and husband but it was obviously very close. She's never been the same without it.
