Naugladur

Naugladur was the king of the Dwarves of Nogrod. He led the attack against Menegroth to capture the Nauglamír. Later he fought with Beren in the Battle of Sarn Athrad and would have slain him, but stumbled and Beren slew him to reclaim the Nauglamír. With his dying words he cursed the treasure that he was bringing back to Nogrod, which Beren dumped in the river.

He is not mentioned by name in The Silmarillion, however his name was revealed in The History of Middle-earth books.
