Though Persephone and Hades become closer than ever after she opens up to him about all she has endured, their peace is shattered when another truth is revealed: Apollo is Zeus's son. The announcement shocks the pantheon, and the king of the gods realizes that the would-be usurper wants Persephone's power to take the throne. Zeus banishes Persephone to the Mortal Realm and cuts it off entirely from the rest of the gods. This decree succeeds in undercutting Apollo's plan, but also inadvertently begins a decade-long divine cold war when Hades strikes back by shuttering the Underworld. With the gods scattered and weakened, Kronos uses the ensuing bedlam to finally escape his imprisonment and begin staging his own coup. Persephone has only one choice: Descend into the Underworld to try to defeat the power-hungry Titan, claim her rightful place as queen, and reunite with her one true love.
