re: GoT "Middle Ground" Thread - Between Seasons Edition ***Spoilers Possible***

Yeah there isn't much written about Dawn. Has it even been mentioned on the show yet? I use to think it was the original Lightbringer, but I have cooled on the theory recently.

To answer TigerintheNO's question, who knows at this point. I think that the main reasons that Valyrian steel works against them is that they were forged with magic & dragons breath. We don't know yet how Dawn was forged, just the rumor that it was forged from the heart of a fallen star. If magic wasn't involved with it being forged, then there is a chance that it can't hurt them. If I had to venture a guess, I'd say that it will probably be able to kill a White Walker.
