One of the Seven Swords of the Noldor, Dolkar Longarm's sword
Heruannon is a hand-and-a-half or bastard sword of more than usual length, made of watered steel, with a steel hilt and an acorn-shaped colourless gem for the pommel. Captured by Varkar at Lantalaure, part of Varkar's hoard at the Slaying, falling into the hands of the Wyrmslayers. It was returned to High King Doronond in Belamir in 1602 by Surya of Tellare.
