The Prophesied 7 have finished their quest. Leo has returned with Calypso, and peace has been restored to the demigod world. But the mortals don't know that. What do they think when our heroes show up in their world?
On their way home after their defeat of Gaea, the seven and Nico are hoping for some peace. But with the arrival of some unwanted visitors, and another Great Prophecy, they may never get any.
*started before the release of BoO, so does not quite line up with that sequence of events. Sorry*
