[@Knight of Doom]

Hey hun, as much as I love the enthusiasm for the character; I cannot accept a child of Persephone as she is unable to have children without disappearing from existence. Her cabin (while she has one in the camp) is very much like that of Hera; it is there to honor her as the Queen of the Underworld and as a Goddess, however it isn't in use unless she herself chooses to stay in the camp.

As a side note though; while I can't accept a child of Persephone, you could always make a child of Demeter who is Persephone's mother.
