Bridge Four is a bridge crew - later an elite military unit - that becomes the heart of Kaladin Stormblessed's story in The Stormlight Archive. Originally a group of expendable slaves forced to carry bridges into battle on the Shattered Plains, Bridge Four was transformed by Kaladin's leadership into a band of fiercely loyal soldiers. Their defiance of the brutal bridgeman system and their refusal to break under impossible conditions makes them one of the most celebrated groups in the series. After earning their freedom, Bridge Four's members become the personal guard of Dalinar Kholin and, later, some of the first new Knights Radiant in millennia. The crew's members - including Teft, Rock, Sigzil, Lopen, and Skar - each bring their own backgrounds and struggles.
