Terra was supposed to be humanity’s second chance. Instead, it became a world of endless migration, industrial expansion, and quiet survival beneath unfamiliar skies. Beneath the glow of three moons and the shadow of war, humanity struggles to rebuild itself across geothermal cities, underground systems, and forests that seem alive in ways no one fully understands. Regina has spent years trying to outrun the memory of Clement, the girl she loved and lost in the violent heart of Axion. Now trapped in a carefully constructed life beside her husband, Clio, and their fragile circle of survival, Regina finds herself haunted by old promises, political unrest, and the growing realization that the past was never truly buried. As tensions rise between the powerful territories of Terra and strange changes continue to spread through the population, old secrets hidden beneath the planet’s surface begin to resurface alongside something far older than humanity itself. On Terra, survival has always demanded adaptation. But some transformations cannot be undone.
