and Galadriel his sister were the guests of Thingol their kinsman in Doriath. Then Finrod was filled with wonder at the strength and majesty of Menegroth, its treasuries and armouries and its many-pillared halls of stone; and it came into his heart that he would build wide halls behind ever-guarded gates in some deep and secret place beneath the hills. Therefore he opened his heart to Thingol, telling him of his dreams; and Thingol spoke to him of the deep gorge of the River Narog, and the caves under the High Faroth in its steep western shore, and when he departed he gave him guides to lead him to that place of which few yet knew. Thus Finrod came to the Caverns of Narog, and began to establish there deep halls and armouries after the fashion of the mansions of Menegroth; and that stronghold was called Nargothrond. In that labour Finrod was aided by the Dwarves of the Blue Mountains; and they were rewarded well, for Finrod had brought more treasures out of Tirion than any other of the princes of the Noldor. And in that time was made for him the Nauglam?r, the Necklace of the Dwarves, most renowned of their works in the Elder Days. It was a carcanet of gold, and set therein were gems uncounted from Valinor; but it had a power within it so that it rested lightly on its wearer as a strand of flax, and whatsoever neck it clasped it sat always with grace and loveliness.
There in Nargothrond Finrod made his home with many of his people, and he was named in the tongue of the Dwarves Felagund, Hewer of Caves; and that name he bore thereafter until his end. But Finrod Felagund was not the first to dwell in the caves beside the River Narog.
Galadriel his sister went not with him to Nargothrond, for in Doriath dwelt Celeborn, kinsman of Thingol, and there was great love between them. Therefore she remained in the Hidden Kingdom, and abode with Melian, and of her learned great lore and wisdom concerning Middle-earth.
But Turgon remembered the city set upon a hill, Tirion the fair with its tower and tree, and he found not what he sought, but returned to Nevrast, and sat in peace in Vinyamar by the shores of the sea. And in the next year Ulmo himself appeared to him, and bade him go forth again alone into the Vale of Sirion; and Turgon went forth, and by the guidance of Ulmo he discovered the hidden vale of Tumladen in the Encircling Mountains, in the midst of which there was a hill of stone. Of this he spoke to none as yet, but returned once more to Nevrast, and there began in his secret counsels to devise the plan of a city after the manner of Tirion upon T?na, for which his heart yearned in exile.
Now Morgoth, believing the report of his spies that the lords of the Noldor were wandering abroad with little thought of war, made trial of the strength and watchfulness of his enemies. Once more, with little warning, his might was stirred, and suddenly there were earthquakes in the north, and fire came from fissures in the earth, and the Iron Mountains vomited flame; and Orcs poured forth across the plain of Ard-galen. Thence they thrust down the Pass of Sirion in the west, and in the east they burst through the land of Maglor, in the gap between the hills of Maedhros and the outliers of the Blue Mountains. But Fingolfin and Maedhros were not sleeping, and while others sought out the scattered bands of Orcs that strayed in Beleriand did great evil they came upon the main host from either side as it was assaulting Dorthonion; and they defeated the servants of Morgoth, and pursuing them across Ard-galen destroyed them utterly, to the least and last, within sight of Angband's gates. That was the third great battle of the Wars of Beleriand, and it was named Dagor Aglareb, the Glorious Battle.
A victory it was, and yet a warning; and the princes took heed of it, and thereafter drew closer their leaguer, and strengthened and ordered their watch, setting the Siege of Angband. which lasted wellnigh four hundred years of the Sun. For a long time after Dagor Aglareb no servant of Morgoth would venture from his gates, for they feared the lords of the Noldor; and Fingolfin boasted that save by treason among themselves Morgoth could never again
