Around the year 260 of the First Age, Azaghal received the Dragon-helm from Telchar, a smith of Nogrod. The Dragon-helm was made shortly after the first appearance of the fire-breathing Dragon Glaurung. The visor on the Dragon-helm shielded the wearer from the Dragon's fire and enthralling gaze.
Azaghal was waylaid by Orcs while traveling along the Dwarf-road in East Beleriand. His life was saved by Maedhros, an Elf who was one of the sons of Feanor. Azaghal gave Maedhros the Dragon-helm in gratitude.
