Sarrassian iron was a metal that was found on asteroids in the Aniras belt. Ancient Sith alchemists valued it in crafting weapons and armor, because it contained special particles that resonated with the dark side of the Force. In 35 ABY, the Symeong Albrekh used Sarrassian iron to weld the cracks on the helmet of Kylo Ren. It shared its name with the Outer Rim Territories astronomical object Sarrassia.
Sarrassian iron was first mentioned in Star Wars: The Rise of Skywalker: The Visual Dictionary, a 2019 reference book written by Pablo Hidalgo. In the Star Wars Legends continuity, Sarrassian iron first appeared in the 2011 novel Knight Errant, written by John Jackson Miller.
