The Valyrian steel blade most commonly referred to as the "catspaw dagger" has become a significant object in the lore of Game of Thrones. It was the weapon we first saw in the hands of a hired catspaw assassin as he attempted to assassinate a comatose Bran Stark (Isaac Hempstead Wright) in season 1, an act that would spark the War of the Five Kings. It's also the weapon that ended the Great War against the white walkers when, in the final season, Arya Stark (Maisie Williams) used it to kill the Night King.
