After the death of Thorin in the Battle of Five Armies, Dain becomes King under the Mountain. He redeems the Arkenstone from Bard with a fourteenth of the treasure, which is used to re-establish Dale. Over the next three years, Bard rebuilds the city of Dale and becomes its ruler. The city begins to prosper again.
They all united against the common enemy, and so was fought the Battle of Five Armies in the valley of Dale. Thorin was killed in the battle, as were his sister-sons Kíli and Fíli. As his "rightful heir," Dáin succeeded Thorin as King under the Mountain, and King of all of Durin's folk.
Dain Ironfoot is their distant cousin who is next in line for the throne after Thorin, Kili, and Fili. Since Thorin, Kili, and Fili all die at the Battle of the Five Armies, Dain Ironfoot becomes the next King under the Mountain.
When Thorin died, he was buried with the Arkenstone. Orcrist was laid upon his tomb. The blade would glow blue if Orcs should approach; thus, they could not take the Mountain by surprise. Thorin was succeeded as leader of Durin's Folk by his cousin Dáin.
Thorin is buried with the Arkenstone and Orcrist; Kili and Fili, who also died in battle, are buried, too. One-fourteenth of the hoard is given to Bard and some is given to Bilbo. Bilbo leaves with Gandalf, Elvenking, and Beorn and spends yuletide with Beorn, staying with him till spring.
Thorin's Company of Dwarves AFTER The Hobbit | Tolkien Explained
Is Gimli the last dwarf?
Though Gimli has no children, he is not the last Dwarf of Middle-earth. After the fall of Sauron, his people continued to thrive in the Lonely Mountain. Gimli made his home in Rohan, in the Glittering Caves of Aglarond, and many of his kinsfolk came with him.
Thorin was disarmed when captured by the Elves of Mirkwood and Orcrist was kept there. However after his death, Thranduil returned Orcrist and placed it upon Thorin's tomb under Erebor, and it "gleamed ever in the dark if foes approached".
Their deaths and Thorin's did not end Durin's line, although did end the branch which had Thror, Thrain, and Thorin Oakenshield. Thorin's cousin, Dain Ironfoot, became King after Thorin's death. Dain's son, Thorin Stonehelm, became King after Dain died in the Battle of Dale. The line continued on after that.
Gimli is the son of Glóin who is introduced in The Hobbit as a member of Thorin Oakenshield's company, also being one of his four third cousins. Thorin himself is a direct descendant of Durin I, even becoming the King of Durin's Folk in his lifetime.
Thorin became the dwarf king at a very young age after the battle. However, Thorin never married nor had any children. The young dwarf king led his people out of Dunland and they finally re-established their home in the Blue Mountains. His younger sister, Dis, later gave birth to two children, Fíli and Kíli.
Fíli and Kíli were Dwarvern brothers and were also the youngest of the thirteen Dwarves who set out with Thorin Oakenshield's company, along with Gandalf and Bilbo Baggins, to reclaim the Lonely Mountain from the dragon Smaug.
Fíli is a Tolkien character who appears in The Hobbit and one of the sequel novels, Unfinished Tales. He is the older brother of Kíli, son of Dís, and the nephew of Thorin Oakenshield. He is a Prince of Durin's Folk who joins his uncle in reclaiming the Lonely Mountain from the dragon, Smaug.
Gimli was born in the Ered Luin in the Third Age, son of Glóin. Gimli had wanted to accompany his father on the quest to reclaim Erebor, but at age 62 he was deemed too young. He was a remote descendant of Durin the Deathless, chief of the Seven Fathers of the Dwarves and ancestor of the Longbeards.
The last we see or hear of Tauriel is her mourning Kíli, confessing her love, and kissing his lips. What happens next? No one knows. Peter Jackson never says, but Evangeline Lilly - the actress who played Tauriel - said in an interview that she thinks Tauriel returned to Mirkwood even though she was banished.
After the fall of Sauron, Thranduil fixed the southern boundary of his realm as the Mountains of Mirkwood, and his realm flourished well into the Fourth Age. He may have stayed on as the king of the Great Forest or left Middle-earth and departed to the Undying Lands.
From TA 2989 to TA 2994, the re-colonization of Moria was an attempted expedition led by Balin to re-take the ancient Dwarven Kingdom of Khazad-dûm. An initial effort was successful in reclaiming some of Moria from the Orcs.
Thrain I, Thrain II, and Thror are dwarves who live during the Third Age of the Sun and belong to the race of Durin. Durin's Line is one of seven original dwarf genealogies, and it's the main surviving Line after the end of the First Age. By the Third Age, even this family tree has shrunk in size.
Simply put, he was the only one available. There were only two dwarves at the council of Elrond, Gimli and his father Gloin. The Dwarves were fighting Sauron's forces constantly in their own campaign and couldn't spare many. Gloin was also much older now, it was absolutely his son's turn to go on a big journey.
With Thorin's death in the battle, Dáin became King of Durin's Folk and King under the Mountain, the first not of the main line. After the battle, Dáin thanked the Great Eagles for their timely intervention, crowning their chief with gold and swearing the Dwarves to everlasting friendship with them.
Death. After ruling as Moria's Lord for about five years, Balin was slain by Orcs on November 10 TA 2994, after going to look upon the Mirromere alone. His body was recovered after a battle, and entombed in the Chamber of Mazarbul.
Kili is based on the character of the same name from The Hobbit by J. R. R. Tolkien. He is also from the film version of The Hobbit by Peter Jackson. Kili has had one love interest: Tauriel. After he is resurrected, they marry and have a son named after his late brother, Fili.
In The Hobbit: The Desolation of Smaug, Orcrist is taken by Legolas when he and a group of Elves capture Thorin's company, and it is subsequently shown being wielded by Legolas when he fights Bolg and other Orcs in defense of Lake-town.
What happened to the Arkenstone after Thorin died?
After the battle, the Arkenstone was placed by Bard upon Thorin's chest within his tomb deep underneath the Lonely Mountain, and so was returned to the earth at last. Bard proclaimed that it until the Lonely Mountain fell, it would "bring good fortune to all" of Thorin's descendants.
The reason for this isn't because the three swords are unique, but instead because they are made from special Elven crafting materials, used in many Elvish blades.
