The Inferno of Prometheus

To save Prometheus, she must give hope to a hero who has lost his own.
Pandora has crossed the Ages in search of Prometheus, defying gods and challenging Fate itself. But when she finally finds the ally she needs, she discovers Herakles broken by grief. Haunted by visions of the children he killed in a moment of madness, the greatest hero of the World no longer seeks glory or honour, only an end to his suffering.
Pandora offers him a new purpose: a mission beyond any he has ever faced. Together, they journey through time with the power of the Box, pursuing the one hope Pandora has never abandoned—the rescue of Prometheus.
Their path leads them into the infernal realm of Tartarus, a domain of demons, cosmic horrors, and the souls of the dead. And as wars rage across the Ages—between Titans and gods, between giants and Olympus—Pandora discovers that even rescuing Prometheus may unleash a catastrophe beyond anything she could have imagined.
Because even the greatest heroes cannot escape the price of defying Fate.
