Sprens are a fictional concept from the Stormlight Archive, a series of epic fantasy novels by Brandon Sanderson. They are described as small, glowing, and often playful creatures that embody the essence of emotions and natural phenomena. Each spren is linked to a specific aspect of the world, such as honor, wisdom, or fear, and they can be seen by certain individuals, particularly those who can harness Surgebinding powers. In the series, sprens play a crucial role in the magic system, as they are integral to the bond between Knights Radiant and their respective spren. This bond allows the Radiants to access unique abilities and powers, which are tied to the nature of their spren. The relationship between a Radiant and their spren is deeply personal and can evolve throughout the story.
