Nalthian is a fictional world from the Cosmere, a universe created by author Brandon Sanderson. It is known for its unique magic system called Awakening, which allows users to animate inanimate objects using a special substance called Breath. Each person in Nalthian can collect Breaths, which are vital for performing magical tasks. The culture of Nalthian is heavily influenced by the concept of Breath and the value placed on life. The society is divided into different classes, with the wealthy often possessing more Breaths. This creates a distinct social hierarchy, where the ability to use magic can significantly impact one's status and power.
