Förmodligen inte
Kapitel 5 Samwell Tarly berättar för Jon Snow att han fann ett redogör för den långa natten som talade om den sista hjälten som slog andra med ett dragonblad och de kunde inte stå emot det och Jon undrar om dragonsteel hänvisar till Valyrian stål.“What about the Others?”
“I found mention of dragonglass. The children of the forest used to give the Night’s Watch a hundred obsidian daggers every year, during the Age of Heroes. The Others come when it is cold, most of the tales agree. Or else it gets cold when they come. Sometimes they appear during snowstorms and melt away when the skies clear. They hide from the light of the sun and emerge by night... or else night falls when they emerge. Some stories speak of them riding the corpses of dead animals. Bears, direwolves, mammoths, horses, it makes no matter, so long as the beast is dead. The one that killed Small Paul was riding a dead horse, so that part’s plainly true. Some accounts speak of giant ice spiders too. I don’t know what those are. Men who fall in battle against the Others must be burned, or else the dead will rise again as their thralls.”
“We knew all this. The question is, how do we fight them?”
“The armor of the Others is proof against most ordinary blades, if the tales can be believed,” said Sam, “and their own swords are so cold they shatter steel. Fire will dismay them, though, and they are vulnerable to obsidian.” He remembered the one he had faced in the haunted forest, and how it had seemed to melt away when he stabbed it with the dragonglass dagger Jon had made for him. “I found one account of the Long Night that spoke of the last hero slaying Others with a blade of dragonsteel. Supposedly they could not stand against it.”
“Dragonsteel?” Jon frowned. “Valyrian steel?”
“That was my first thought as well.”
Så medan vi inte har något definitivt svar verkar det mycket troligt att åtminstone den sista hjälten av de första männen använde Valyrian stål för att döda en vit walker.
