It's been a century since "the great consumption." Humanity has been devoured to the edge of extinction by the ever-ravenous Shivers - terrifying, shapeless creatures that latch onto their hosts, tormenting them over time before consuming them all at once. The last of civilization lives in the crumbling city of Atlas, where they subsist on processed insects and await their inevitable fate. Anthem is the city Exilist, tasked with trapping the Shivers and banishing them to the malevolent Deadlands outside the city walls. But Anthem is ailing and destined to soon fall victim to his own Shiver, a fate he's reluctantly accepted. As Anthem begins to withdraw from his world, a threat he's unprepared for comes hurtling home. If he is to save anyone, he will have to travel into the Deadlands in search of a remedy to tame these creatures. But no Atlas dweller has ever made it back alive, and Anthem must confront his own darkness before humankind is forever lost to the monsters in our shadows.
