Following the trail of Nicol Bolas, the Gatewatch are brought to a desert plane of the Elder Dragon's own design, Amonkhet. There, they find a culture that worships Bolas, and a people who eagerly throw themselves into the deadly Five Trials in search of a promised afterlife. But all isn't as it seems, as the Gatewatch soon finds a deeper history of a plane that has suffered under the gaze of the "God Pharaoh" Nicol Bolas.
