Long ago, colossal spirits with star-sized bodies held up the sky and roamed the cosmos, clan leaders of strange lineage broke open the void to forge new worlds, and Qi Warriors journeyed across the stars to teach mortals. Then, for reasons no one knows, that age quietly ended: the realms were cut off from one another and the giant spirits vanished one by one. Thousands of years afterward, a young man named Nie Tian draws on the might of that vanished era through a single drop of blood. The result is a 24-episode action fantasy ONA built on a vast, mythic backdrop.
