Act 1

Serenity Jackson, the mother of the infamous son of Poseidon, Percy Jackson, has a life she never talked about. Her life as the rightful Queen Rhaenyra Targaryen first of her name.

She still is thinking about marrying Poseidon or not but it just reminds her of her old life. She can't choose, she doesn't want to go through this again.

What's wrong with Percy finding out who his mom is like in the past?
