With dreams of paradise, humanity slaughtered them and stole their powers, opening the path to become more – to ascend. Instead, they nearly destroyed the world. Vast hive cities serve as the final bastions against the crumbling of reality. New Vultun is the greatest of them all, and within its borders, ascenders wage war to determine the laws of existence itself. The world descends ever deeper into ruination. Avo was born a weapon, a slave to his instincts and his masters. He and his brothers were made to burn New Vultun to ashes. Everything changes when Avo gains immortality and becomes heir to an impossible legacy. He must ascend the megacity of New Vultun. He must challenge the very tyrants that usurped the gods. He must finally free the world from chains.
