After a cataclysmic war of the gods, the last of humanity huddles in Bastion, a colossal ringed city. Beyond the outermost wall lies endless desert haunted by the souls of all the world’s dead. Trapped in a rigid caste system, Nuru, a young street sorcerer, lives in the outer ring. She dreams of escape and freedom. When something contacts her from beyond the wall, she risks everything and leaps at the opportunity. Mother Death, a banished god seeking to reclaim her place in Bastion’s patchwork pantheon, has found her way back into the city. Akachi, born to the wealth and splendour of Bastion’s inner rings, is a priest of Cloud Serpent, Lord of the Hunt. A temple-trained sorcerer, he is tasked with bringing peace to the troublesome outer ring. Drawn into a dark and violent world of assassins, gangs, and street sorcerers, he battles the spreading influence of Mother Death in a desperate attempt to save Bastion. The gods are once again at war.

Smoking Mirror spoke in smoke and stone. Having returned Mother Death to Bastion, Nuru flees to the inner rings. The Loa heretics seek to turn her to their own ends and topple the nahual from power. As Bastion crumbles, Nuru contemplates the ultimate blasphemy: A world without gods. Broken by his battle with Mother Death, Akachi awakens with renewed purpose. He must hunt the blasphemers who would destroy his beloved city. Armed with the Staff of the Fifth Sun he stalks Nuru through Bastion’s rings. The survival of all humanity rests on his shoulders. Nothing is as it seems. Smoking Mirror, god of discord and strife, plots behind the scenes. He manipulates gods and men alike in a game as old as time. From the lowest Grower to the gods at her heart, Bastion is once again at war.

Cloud Serpent spoke in death and venom. Half Bastion’s pantheon are dead, and more gods fall with every passing day. The underworld is ash, seared clean of souls by the Staff of the Fifth Sun. The nahual war among themselves, each sect battling to bring their deity to dominance. The veil is torn, the ghosts of dead gods, demons, and banished sorcerers clawing their way back into the city. Eternal Bastion is divided, her ancient stone crumbling. Left brittle and cracked by the death of her friends, Nuru swears to rid Bastion of parasitic gods. Wielding the Staff of the Fifth Sun, the deranged Mother Death riding her soul, she stalks the pantheon one by one. Fleeing his failures, riding the ragged edge of brain-burn, Akachi pursues his prey into the inner rings. If he doesn’t catch them before they murder the last god, all Bastion is doomed. For religion does not play a part in a civilization, it defines it.
