As we know, Game of Thrones is a show which lends itself to fans coming up with a shit-ton of theories, from the confirmed (R+L=J), to the ridiculous (Tyrion being the son of Daenerys and Khal Drogo – yes, really).

One of these latest theories is pretty convincing though. It revolves around the Iron Throne itself, and how it might end up being the key to defeating the White Walkers.

In this 2014 interview picked up by redditor batteryramdar, George R.R. Martin confirms that Valyrian steel is forged using dragon fire. Valyrian steel is going to be extremely important in the last two seasons of the show, as we know it's one of the few things that can actually kill White Walkers. We've already got three dragons (thanks Daenerys), but magic and extremely advanced steel working skills (known only to the extinct Valyrians) are also needed to forge Valyrian steel. It could be that the only hope of learning how to forge new Walker-bashing weapons might lie with Sam and the things he's going to discover in the world's most gigantic library (it must be something important, right?)

But where this theory gets even more interesting is when we bring the Iron Throne into the equation.

See, as another Reddit user, aonf, points out, the Iron Throne is made out of regular swords which were fused together with dragon fire – and dragon fire is capable of turning regular substances into stuff that's capable of butchering White Walkers.

This means that if the Iron Throne was disassembled, there would suddenly be 1,000 ice zombie-ready swords at (hopefully) Jon and Daenerys' disposal to create an army capable of stopping Westeros from turning into a very cold Walking Dead spin-off.

It could be Sam that comes up with this plan (again, there's no way we've spent six seasons watching him do very little for him not to have some incredibly important part to play in this whole thing). There's also a ~hell of a lot~ of symbolism in the idea of ripping apart the Iron Throne – it's not like it's really caused anything more than a whole bunch of wars and deaths since Aegon the Conquerer decided a heap of sharp swords would be a comfortable thing to park his butt on as he ruled the Seven Kingdoms. Of course, this is just a theory, and could end up being total rubbish – but it's a pretty cool idea, and might make the perfect ending for when we finally have to wave goodbye to Westeros some time in 2018.
