Zydn is a recent and distinctive given name created by American author Brandon Sanderson for his epic fantasy series "The Stormlight Archive," first published in 2010. It was originally intended as the name of a magical, intelligent entity called a spren in the world of Roshar, but has since begun to be used as a human name in real life, particularly in English-speaking countries. Its pronunciation is typically /ZID-en/, with no known meaning or history outside of Sanderson's literary universe.
