§ Of Túrin Turambar The Silmarillion

In the time that followed Túrin grew high in favour with Orodreth, and well-nigh all hearts were turned to him in Nargothrond. For he was young, and only now reached his full manhood; and he was in truth the son of Morwen Eledhwen to look upon: dark-haired and pale-skinned, with grey eyes, and his face more beautiful than any other among mortal Men, in the Elder Days. His speech and bearing were that of the ancient kingdom of Doriath, and even among the Elves he might be taken for one from the great houses of the Noldor; therefore many called him Adanedhel, the Elf-Man. The sword Anglachel was forged anew for him by cunning smiths of Nargothrond, and though ever black its edges shone with pale fire; and he named it Gurthang, Iron of Death. So great was his prowess and skill in warfare on the confines of the Guarded Plain that he himself became known as Mormegil, the Black Sword; and the Elves said: 'The Mormegil cannot be slain, save by mischance, or an evil arrow from afar.' Therefore they gave him dwarf-mail, to guard him; and in a grim mood he found also in the armouries a dwarf-mask all gilded, and he put it on before battle, and his enemies fled before his face.
