Unnarr was a male Longbeard dwarf residing in Thorin's Halls. Sometime before the War of the Ring, he was one of the dwarves who participated in Dwalin's expedition to the Dourhands' lands, south of the city. He was Captain of the Guard in the city. At some point he asked a fellow Longbeard dwarf to recover the weapons that had been stolen from the city's armory cave and soon discovered they had been stolen by the Dourhands.
