A legendary metal forged in the ancient Valyrian Freehold using dragonfire and magic. Valyrian steel blades are lighter, stronger, and sharper than ordinary steel, never need sharpening, and have a distinctive rippled pattern. The secret of forging new Valyrian steel was lost with the Doom of Valyria. A handful of Valyrian steel swords survive in Westeros as prized family heirlooms, including Ice (Stark), Longclaw (Mormont), and Heartsbane (Tarly). Like dragonglass, Valyrian steel can kill Others.
