WARNING: Possible spoilers for Game of Thrones ahead. Proceed with caution.
With Season 5 of Game of Thrones having come to a dramatic close, fans of the show now have to wait until April 2016 for another fix of the Westerosi drama. With things really heating up in the back half of Season 5, it looks as thought we should prepare ourselves for one hell of a Season 6, and possibly the beginning of the longest and most devastating winter Westeros has ever seen.
However, one fan over on Reddit who goes by the username VarshaGT has a pretty cool theory about something which may help with the devastating winter Westeros is about to undergo: using the Iron Throne to help destroy the White Walkers.
What does the Iron Throne have to do with it?
VarshaGT theorizes that because the Iron Throne was constructed by a 1,000 swords all put together by the fiery breath of Aegon's dragon, Balerion the Black Dread, that the swords used in the construction of the Iron Throne may in fact be made of Valyrian steel. Valyrian steel is one of the few things known to kill White Walkers, alongside Dragonglass.
Therefore, if the Iron Throne was melted down and the metal was reforged into swords, an army (a small army at the very least) could be armed with swords that are proven to be able to kill White Walkers.
Why would this be awesome in the show?
Following the death of King Robert the War of the Five Kings broke out, with , Joffrey Baratheon, Robert's two younger brothers, Stannis Baratheon and Renly Baratheon, Robb Stark, and Balon Greyjoy all battling for the throne. If it so happened that the destruction of the Iron Throne, the very thing everyone was fighting to claim, was the only way to save Westeros, it would indeed be a very poetic end.
Furthermore the destruction would work in well with Daenerys' speech when she claims that she will break the wheel of the great families of Westeros (the idea being that the great families are all spokes in a wheel, each taking their turn at the top, crushing everyone below them)
Why it could be wrong
Of course with any theory there are strengths and weaknesses, and in this case the weakness is that we actually have no idea how Valyrian steel is actually made, with the last Valyrian steel sword being forged at the Doom of Valyria - approximately 400 years before the War of the Five Kings.
While dragon's fire was possibly used in the process, it is unlikely it is the only thing needed to make steel Valyrian, otherwise by that same logic many of the swords used in the fighting pits at Meereen would now also be Valyrian.
However weaknesses aside, this theory does have a sort of poetic and symbolic nature to it that would make it an awesome theory to come true in future seasons, perhaps it's even too good for the writers of Game of Thrones to resist. Only time will tell!
