Your father, Ouranos, had been trapped in his own domain, the sky, for thousands of years. How you were made was... a good question. Probably one you shouldn't ask.

Anyways, you seemed to be his favorite of his offspring, and had made some Nymphs have all the deities give you a sort of blessing as a baby.

But you also ended up becoming this generation's fertility goddess(or deity? Depends on gender).

You're maybe, like, 15 when he figures it out. You're 16, and sitting up in the clouds, eating something when you hear your father approach you from behind.
