The epic conclusion of last night’s Game of Thrones episode “Hardhome” put a theory to the test: Will Valyrian steel defeat the Others? This is a question posed by both the books and TV series, but one that wasn’t answered until this episode aired (no, not even in the books). Sure, any Tarly can wield a chunk of Dragonglass and if they’re lucky enough they might even fell a White Walker. But now that Valyrian steel has been shown to be more than equal to the Others’ weapons, the royal houses of the Known World had best be polishing up their ancestral blades.
What is Valyrian steel? Why is it so important? And why is the ice-crowned, blue-eyed fellow known as the Night’s King so concerned with it? Let’s explore.
