From A Wiki of Ice and Fire
Vigilance is a Valyrian steel longsword belonging to House Hightower.
Ormund Hightower, Lord of the Hightower, wielded the blade during the Dance of the Dragons, in which he fought for King Aegon II Targaryen. After the Battle on the Honeywine, he used it to knight Prince Daeron Targaryen, his squire and the king's brother, dubbing him "Ser Daeron the Daring" for turning the battle in their favor with Daeron's dragon, Tessarion.
Lord Ormund was killed by Roderick Dustin, Lord of Barrowton, during the First Battle of Tumbleton. It is unknown what happened to Vigilance afterwards.
