Fabrials are magical devices found in the world of The Stormlight Archive, a series of fantasy novels by Brandon Sanderson. They are created using sprens, which are ethereal beings that embody various concepts and emotions. Fabrials can perform a range of functions, such as healing, enhancing physical abilities, or manipulating the environment, depending on the type of spren used and the design of the fabrial. These devices are often crafted by skilled artisans known as Soulcasters or Fabrial makers. The effectiveness of a fabrial relies on the proper binding of the spren and the materials used in its construction. As a result, the study and creation of fabrials are important aspects of the magical system in the series.
