He is a child, he is 11 years old right now. But thank you for reading.

He still is the son of Poseidon and Sally, but things happened, Hera took a liking of him and he end up being adopted by her :D (happened on chapter 10, so isn't too much of a spoiler with the synopsis)

I edited the chapter again

He still is the son of Poseidon and Sally, and in this story Sally is a daugther of Athena. Hera is still unrelated to Percy, but took a liking of him

Yes for both! :D

There is a harem, but things happen in the story that would be spoilers if I tell you who is in it. Sorry!

Yes! :D
