Euron Greyjoy, the Crow's Eye, returned from a lifetime of reaving and stranger voyages with a hoard of Valyrian wonders. At the kingsmoot on Old Wyk, where the captains and kings gathered to choose Balon's successor, Euron flung handfuls of Valyrian-steel daggers into the crowd as gifts — blades most lords of Westeros could never hope to own, scattered like coppers to buy a crown.
He is said to wear a suit of black Valyrian-steel scale beneath his clothes besides, armour his own brother Victarion reckons would have cost a kingdom even before the Doom of Valyria.
Status: extant, in the hands of Euron and the men of the Iron Fleet.
