Eöl, always called the Dark Elf was an Elf of Beleriand and a metallurgist of high skill. He was a Sinda who lived in Nan Elmoth, nominally part of Doriath. A great smith and friend of the Dwarves of Nogrod and Belegost, Eöl devised Galvorn, a black metal of great strength and malleability, which he fashioned into armour that he wore when he went abroad. He forged two great black swords from a meteorite's metal, but had to give the sword Anglachel to Thingol as tribute for living in Nan Elmoth. The other sword, Anguirel, he kept for himself.
