The Silmarillion

But in Dorthonion the lordship of the people of Beor and the country of Ladros was given to Boromir, son of Boron, who was the grandson of Beor the Old.

The sons of Hador were Galdor and Gundor; and the sons of Galdor were Hurin and Huor; and the son of Hurin was Turin the Bane of Glaurung; and the son of Huor was Tuor, father of Earendil the Blessed. The son of Boromir was Bregor, whose sons were Bregolas and Barahir; and the sons of Bregolas were Baragund and Belegund. The daughter of Baragund was Morwen, the mother of Turin, and the daughter of Belegund was Rian, the mother of Tuor. But the son of Barahir was Beren One-hand, who won the love of Luthien Thingol's daughter, and returned from the Dead; from them came Elwing the wife of Earendil, and all the Kings of Numenor after.

All these were caught in the net of the Doom of the Noldor; and they did great deeds which the Eldar remember still among the histories of the Kings of old. And in those days the strength of Men was added to the power of the Noldor, and their hope was high; and Morgoth was straitly enclosed, for the people of Hador, being hardy to endure cold and long wandering, feared sot at times to go far into the north and there keep watch upon the movements of the Enemy. The Men of the Three Houses throve and multiplied, but greatest among them was the house of Hador Goldenhead, peer of Elven-lords. His people were of great strength and stature, ready in mind, bold and steadfast, quick to anger and to laughter, mighty among the Children of Iluvatar in the youth of Mankind. Yellow-haired they were for the most part, and blue-eyed; but not so was Turin, whose mother was Morwen of the house of Beor. The Men of that house were dark or brown of hair, with grey eyes; and of all Men they were most like to the Noldor and most loved by them; for they were eager of mind, cunning-handed, swift in understanding, long in memory, and they were moved sooner to pity than to laughter. Like to them were the woodland folk of Haleth, but they were of lesser stature, and less eager for lore. They used few words, and did not love great concourse of men; and many among them delighted in solitude, wandering free in the greenwoods while the wonder of the lands of the Eldar was new upon them. But in the realms of the West their time was brief and their days unhappy.

The years of the Edain were lengthened, according to the reckoning of Men, after their coming to Beleriand; but at last Beor the Old died when he had lived three and ninety years, for four and forty of which he had served King Felagund. And when he lay dead, of no wound or grief, but stricken by age, the Eldar saw for the first time the swift waning of the life of Men, and the death of weariness which they knew not in themselves; and they grieved greatly for the loss of their friends. But Beor at the last had relinquished his life willingly and passed in peace; and the Eldar wondered much at the strange fate of Men, for in all their lore there was no account of it, and its end was hidden from them.

Nonetheless the Edain of old learned swiftly of the Eldar all such art and knowledge as they could receive, and their sons increased in wisdom and skill, until they far surpassed all others of Mankind, who dwelt still east of the mountains and had not seen the Eldar, nor looked upon the faces that had beheld the Light of Valinor.

Chapter 18

Of the Ruin of Beleriand and the Fall of Fingolfin Now Fingolfin, King of the North, and High King of the Noldor, seeing that his people were become numerous and strong, and that the Men allied to them were many and valiant, pondered once more an assault upon Angband; for he knew that they lived in danger while the circle of the siege was incomplete, and Morgoth was free to labour in his deep mines, devising what evils none could foretell ere he should reveal them. This counsel was wise according to the measure of his knowledge; for the Noldor did not yet comprehend the fullness of the power of Morgoth, nor understand that their unaided war upon him was without final hope, whether they hasted or delayed. But because the land was fair and their kingdoms wide, most of the Noldor were content with things as they were, trusting them to last, and slow to begin an assault in which many must surely perish were it in victory or in defeat Therefore they were little disposed to hearken to Fingolfin, and the sons of Feanor at that time least of all. Among the chieftains of the Noldor Angrod and Aegnor alone were of like mind with the King; for they dwelt in regions whence Thangorodrim could be descried, and the threat of Morgoth was present to their thought. Thus the designs of Fingolfin came to naught, and the land had peace yet for a while.

But when the sixth generation of Men after Beor and Marach were not yet come to full manhood, it being then four hundred years and five and fifty since the coming of Fingolfin, the evil befell that he had long dreaded, and yet more dire and sudden than his darkest fear. For Morgoth had long prepared his force in secret, while ever the malice of his heart grew greater, and his hatred of the Noldor more bitter; and he desired not only to end his foes but to destroy also and defile the lands that they had taken and made fair. And it is said that his hate overcame his counsel, so that if he had but endured to wait longer, until his designs were full, then the Noldor would have perished utterly. But on his part he esteemed too lightly the valour of the Elves, and of Men he took yet no account.

There came a time of winter, when night was dark and without moon; and the wide plain of Ard-galen stretched dim beneath the cold stars, from the hill-forts of the Noldor to the feet of Thangorodrim. The watch-fires burned low, and the guards were few; on the plain few were waking in the camps of the horsemen of Hithlum. Then suddenly Morgoth sent forth great rivers of flame that ran down swifter than Balrogs from Thangorodrim, and poured over all the plain; and the Mountains of Iron belched forth fires of many poisonous hues, and the fume of them stank upon the air, and was deadly. Thus Ard-galen perished, and fire devoured its grasses; and it became a burned and desolate waste, full of a choking dust, barren and lifeless. Thereafter its name was changed, and it was called Anfauglith, the Gasping Dust Many charred bones had there their roofless grave; for many of the Noldor perished in that burning, who were caught by the running flame and could not fly to the hills. The heights of Dorthonion and Ered Wethrin held back the fiery torrents, but their woods upon the slopes that looked towards Angband were all kindled, and the smoke wrought confusion among the defenders. Thus began the fourth of the great battles, Dagor Bragollach, the Battle of Sudden Flame.

In the front of that fire came Glaurung the golden, father of dragons, in his full might; and in his train were Balrogs, and behind them came the black armies of the Orcs in multitudes such as the Noldor had never before seen or imagined. And they assaulted the fortresses of the Noldor, and broke the leaguer about Angband, and slew wherever they found them the Noldor and their allies. Grey-elves and Men. Many of the stoutest of the foes of Morgoth were destroyed in the first days of that war, bewildered and dispersed and unable to muster their strength. War ceased not wholly ever again in Beleriand; but the Battle of Sudden Flame is held to have ended with the coming of spring, when the onslaught of Morgoth grew less.
