Nalthis 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 individuals to animate inanimate objects using a special substance called Breath. Each person on Nalthis is born with a single Breath, and they can acquire more through various means, enhancing their magical abilities. The culture of Nalthis is heavily influenced by the concept of Breath and its value. The people often engage in trade, giving away their Breaths for goods or services. The ruling class, known as the Nalthians, has a significant impact on society, and the political landscape is shaped by the use of magic and the distribution of Breath among its citizens.
