On the brink of world destruction, as darkness swallowed up humanity’s last hope, seven heroes were summoned from another world. The gods themselves chose them, bestowing divine power to confront the power-hungry Demon King. A great war ensued. The ground shook, the sky split, and blood was shed to save the world. But just as victory was within reach, the seven heroes vanished—vanished without a trace. No graves, no ruins, not even a single person could remember their faces, names, or origins. The world was saved, but their history was lost. Only faint rumors remained: of forgotten heroes.
