Dragon-helm of Dor-lómin
This article or section needs more/new/more-detailed sources to conform to a higher standard and to provide proof for claims made.
The Dragon-helm of Dor-lómin, also known as the Helm of Hador, was a visored steel helm, embossed and embellished with gold, that bore as its crest the head of Glaurung.
The helm was forged sometime between F.A. 260 and 300 by the dwarf-smith Telchar for his lord Azaghâl, who then gave it as a gift to Maedhros. He in turn passed it on to his cousin Fingon. In 423 Fingolfin, the High King of the Noldor, created the fiefdom of Dor-lómin and made Hador the first Lord of Dor-lómin. To celebrate the event Fingon presented Hador with the helm.
The Dragon-helm was crafted for a Dwarf and was too large and heavy for an Elf. Even Men found the helm was too massive, and only Hador had the strength to wear it. It passed through Hador's descendants until Túrin Turambar finally bore it to battle.
Túrin was monstrous in war and took one of his many titles from it: Gorthol, the "Dread Helm". The last clear record of the Dragon-helm is at the Battle of Tumhalad, where Túrin is known to have worn it.
