Ciríon, and éomer took again the Oath of Eorl. Often he fulfilled it. For though Sauron had passed, the hatreds and evils that he bred had not died, and the King of the West had many enemies to subdue before the White Tree could grow in peace. And wherever King Elessar went with war King éomer went with him; and beyond the Sea of Rhûn and on the far fields of the South the thunder of the cavalry of the Mark was heard, and the White Horse upon Green flew in many winds until éomer grew old.

DURIN’S FOLK
Concerning the beginning of the Dwarves strange tales are told both by the Eldar and by the Dwarves themselves; but since these things lie far back beyond our days little is said of them here. Durin is the name that the Dwarves used for the eldest of the Seven Fathers of their race, and the ancestor of all the kings of the Longbeards. 1 He slept alone, until in the deeps of time and the awakening of that people he came to Azanulbizar, and in the caves above Kheled-zâram in the east of the Misty Mountains he made his dwelling, where afterwards were the Mines of Moria renowned in song.
There he lived so long that he was known far and wide as Durin the Deathless. Yet in the end he died before the Elder Days had passed, and his tomb was in Khazad-dûm; but his line never failed, and five times an heir was born in his House so like to his Forefather that he received the name of Durin. He was indeed held by the Dwarves to be the Deathless that returned; for they have many strange tales and beliefs concerning themselves and their fate in the world.
After the end of the First Age the power and wealth of Khazad-dûm was much increased; for it was enriched by many people and much lore and craft when the ancient cities of Nogrod and Belegost in the Blue Mountains were ruined at the breaking of Thangorodrim. The power of Moria endured throughout the Dark Years and the dominion of Sauron, for though Eregion was destroyed and the gates of Moria were shut, the halls of Khazad-dûm were too deep and strong and filled with a people too numerous and valiant for Sauron to conquer from without. Thus its wealth remained long unrav-ished, though its people began to dwindle.
It came to pass that in the middle of the Third Age Durin was again its king, being the sixth of that name. The power of Sauron, servant of Morgoth, was then again growing in the world, though the Shadow in the Forest that looked towards Moria was not yet known for what it was. All evil things were stirring. The Dwarves delved deep at that time, seeking beneath Baraz-inbar for mithril, the metal beyond price that was becoming yearly ever harder to win. 1 Thus they roused from sleep 2 a thing of terror that, flying from Thangorodrim, had lain hidden at the foundations of the earth since the coming of the Host of the West: a Balrog of Morgoth. Durin was slain by it, and the year after Náin I, his son; and then the glory of Moria passed, and its people were destroyed or fled far away.
Most of those that escaped made their way into the North, and Thráin I, Náin’s son, came to Erebor, the Lonely Mountain, near the eastern eaves of Mirkwood, and there he began new works, and became King under the Mountain. In Erebor he found the great jewel, the Arkenstone, Heart of the Mountain. 3 But Thorin I his son removed and went into the far North to the Grey Mountains, where most of Durin’s folk were now gathering; for those mountains were rich and little explored. But there were dragons in the wastes beyond; and after many years they became strong again and multiplied, and they made war on the Dwarves, and plundered their works. At last Dáin I, together with Frór his second son, was slain at the doors of his hall by a great cold-drake.
Not long after most of Durin’s Folk abandoned the Grey Mountains. Grór, Dáin’s son, went away with many followers to the Iron Hills; but Thrór, Dáin’s heir, with Borin his father’s brother and the remainder of the people returned to Erebor. To the Great Hall of Thráin, Thrór brought back the Arkenstone, and he and his folk prospered and became rich, and
