Plot Summary

The narrative opens on the days following the last battle of Words of Radiance. Dalinar Kholin, the high prince of war, leads the Alethi people in fighting the enemy—the deity-like being called Odium. Dalinar also instructs the Alethi in adapting to their new environment in a colossal tower, Urithiru, that was once the home of the ancient Knights Radiant, an order of humans with mystical powers provided through their bonds with creatures called spren.

Creatures that the humans refer to as Voidbringers (who call themselves the Fused) have returned to Roshar, the planet where the novel is set and the home of the main characters, bringing their Radiant-like powers and fighting for Odium.
