Heroic Age unfolds in a distant future shaped by an ancient promise from the Golden Race, a civilization that once called other sentient peoples to join them among the stars. Three of those peoples answered and became the Bronze, Silver, and Heroic Tribes, while humanity reached space on its own and earned the name Iron Tribe. What should have been a shared cosmic future instead collapses into conflict, as the stronger races push humanity toward extinction and the Iron Tribe is forced to fight for its place in the universe.
The story begins when Princess Deianeira follows a prophecy left behind by the Gold Tribe and sets out in search of the mysterious being said to hold the key to humanity’s survival. Her search leads her to an abandoned planet, where she discovers a wild-haired boy whose existence could change the fate of the Iron Tribe and the balance of power among the stars. As Deianeira and the boy are drawn into a widening war, Heroic Age follows their uneasy alliance across space, with their bond at the center of a struggle that reaches beyond one species’ survival and toward the destiny of the universe itself.
