The phrase “watchers on the rim” is a recurrent motif in Wind and Truth. Szeth is the first character to use the phrase when he quotes a line often spoken by Dalinar: “‘Is that not what the Radiants are?’ Szeth said. ‘Watchers on the rim, as Dalinar says? A pleasant term for an unpleasant idea—people who must kill so ordinary men and women can live peaceful lives’” (373). Although Kaladin disagrees with Szeth’s cynical interpretation of the phrase, Szeth’s statement addresses the tension inherent in the motif. The author uses the concept of “watchers on the rim” to acknowledge the sacrifices that leaders and military forces must make to protect the things they hold dear.

Throughout the novel, different characters consider the idea and assess whether or not their sacrifices as “watchers at the rim” are “worth it” (479). The motif enhances the novel’s consideration of The Importance of Personal Accountability and Choice and The Lasting Effects of Trauma; these issues gain prominence as the characters wonder at the sacrifices necessary to achieve collective well-being and decide whether they are equal to the task. In Part 10, for example, Adolin and the deadeye spren connect with the phrase, reclaiming it and accepting the challenge inherent within it.
