Frár was one of the Dwarves who followed Balin from the Lonely Mountain on his expedition to retake Moria for Durin's folk. The Dwarves seemed at first to succeed in their mission, as they recovered their ancient home beneath the Misty Mountains. After only a few years, though, the Orcs and their allies invaded once again, attacking through the East-gate of Moria. The Orcs forced their way across the perilously narrow Bridge of Khazad-dûm, as the Dwarves lost ground in their desperate defence of the Second Hall at the western end of the span. Frár was among the Dwarves who fell in that battle.
