Gorshalach, (the Dark Render) was one of the the most powerful weapons in the universe. This massive greatsword was originally wielded by Sargeras while he was a member of the TitanPantheon. When Sargeras fell to his madness, Gorshalach, being semi-sentient, sundered itself into two 'Shatterbound pieces' to prevent the fallen Titan from wielding it. One fragment was claimed by Sargeras and reforged into Gorribal, while the other was claimed by Aggramar and reforged into Taeshalach. If both fragments are ever possessed by a non-evil being, they can be combined to reform Gorshalach.
