Stannis did claim to wield it, but that believe was mistaken and was pretty evident in the books. The books did seem to indicated that it was a relic and possibly some other sword, though there was nothing definitive.Maybe I'm confusing the books and the show but shouldn't Lightbringer already be a relic at this point? Didn't Stannis claim to wield it?
Haven't read the books for a while though so I could be totally off base.



but Arya and Sansa. Really though, wtf Arya?
I wonder if the Night King will think tactically, send it to King's Landing to attack and then all the people will assume it's Dany's doing, and her plans to get the people of Westeros behind her will go down the drain.
