...yes and no. [How do you explain...okay, whatever, let's back up here.] That was Camp Half-Blood, a training camp for demigods. It's not that far from the Long Island Sound. But it's only for demigods of Greek parentage. My father is Hades. There's a second camp in California just outside of San Francisco called Camp Jupiter. It's a training grounds for Roman demigods. It's where Reyna's from, and where my half-sister lives. Her name is Hazel. She's a daughter of Pluto.

[...] I didn't know about Hazel until quite recently. About a year now, maybe a little more. But my other sister was a child of Hades as well.

[Was. You know how that goes. He tries not to linger though.] Gods exist. [He thinks back to the memory.] Jason's a son of Zeus, Will's the son of Apollo, Percy's the son of Poseidon and Annabeth's a daughter of Athena. The other people Jason mentioned, Piper and Leo, they're the daughter of Aphrodite and son of Hephaestus. Most demigods also have different mortal parents from their siblings.
