A Dwarf-smith of Khazad-dum in the Second Age who built the Doors of Durin (the West-gate of Moria) in collaboration with Celebrimbor of Eregion. The inscription on the doors reads "The Doors of Durin, Lord of Moria. Speak, friend, and enter. I, Narvi, made them. Celebrimbor of Hollin drew these signs."
