10 Most Powerful Items In Game Of Thrones

6. White Walker Ice Blade

Things are about to get a whole lot colder, with the Wall and everything beyond it set to play host to some of the most critical moments in the entire series. The White Walkers will be at the heart of everything, until somebody finally gets to the heart of a White Walker. That task certainly isn't simple.

The ice demons come armed with clear swords, incredibly described by George R.R. Martin in the book series as being: "alive with moonlight, translucent, a shard of crystal so thin that it seemed almost to vanish when seen edge-on. There was a faint blue shimmer to the thing, a ghost-light that played around its edges." They're incredibly powerful, and will be used to carve a path all the way to King's Landing if that is the White Walker's journey.
