The Invaders arrived on Earth and spent generations manipulating humanity through Returners, sowing division and preventing the birth of Ascendants. Twelve planets had already fallen, and the Thirteenth Planet—Earth—was destined to share the same fate. In the distant future, humanity launched a final assault against the Invaders, only to suffer complete defeat. But at the last moment, Choi Taegun sent his memories back through time. Armed with knowledge of humanity’s downfall, he learns that strength alone is not enough. To save the world, he must find the Seeds of Ascension, change a broken society, and raise the disciples who will become humanity’s greatest hope.
