The Orogenes, who wield earth's power, are the reason for life's survival; however, society shuns and exploits them. A red rift tears through the land in The Fifth Season, spewing enough ash to darken the sky for years. Without the resources needed to get through the long, dark night, war will erupt across the Stillness, and Essun will be forced to track down her missing daughter through this deadly, dying land.
