For those who do not know the Great Royal Sword of Stormwind is the blade of Anduin Lothar that was shattered when Orgrim Doomhammer defeated Lothar at Blackrock Spire, however we do not know what happened to the pieces of the blade.
What we know:
We know that Turalyon carried the broken sword into battle with him into Draenor and the blade he wields now kind of looks like a reforged version of the sword. However in the Blackwing Lair raid Nefarian drops a weapon called Ashkandi, Greatsword of the Brotherhood that is heavily implied to be a reforged version of Lothar’s blade, so one must ask, which blade is real?
My theroy:
My Theory is that Turalyon’s sword was forged using the hilt portion of the Great Royal Sword that he carried with him into Draenor. However sometime after the Second War, Nefairan recovered the blade portion of the sword that was broken off during the battle with Doomhammer and he used this to forge Ashkandi in order to help his own schemes, or even those of his sister Onyxia.
What are your thoughts on what happened to the blade?
