Quote from : The Last Olympian Book

Kronos couldn't have risen if it hadn't been for a lot of demigods who felt abandoned by their parents," I said. "They felt angry, resentful, and unloved, and they had a good reason." Zeus's royal nostrils flared. "You dare accuse-" "No more undetermined children," I said. "I want you to promise to claim your children-all your demigod children-by the time they turn thirteen. They won't be left out in the world on their own at the mercy of monsters. I want them claimed and brought to camp so they can be trained right, and survive." "Now, wait just a moment," Apollo said, but I was on a roll. "And the minor gods," I said. "Nemesis, Hecate, Morpheus, Janus, Hebe--they all deserve a general amnesty and a place at Camp Half-Blood. Their children shouldn't be ignored. Calypso and the other peaceful Titan-kind should be pardoned too. And Hades-" "Are you calling me a ?" Hades bellowed.
