Madog steel, a nearly indestructible and exceptionally resilient type of durasteel, was forged by Tem Madog, the Je'daii Temple Master of Vur Tepe. This material served as the main building block for a Je'daii's Force-imbued blade. Its supposed invincibility was disproven when Xesh, the Force Hound, shattered the Madog steel swords wielded by Sek'nos Rath and Hawk Ryo with his Forcesaber during their confrontation as the three Je'daii Journeyers.
