Though Gimli has no children, he is not the last
The seven surviving dwarves from Thorin's company likely fought during the Battle of Dale, or remained behind to defend the Lonely Mountain. The relative absence of dwarves in The Lord of the Rings can be attributed to Tolkien's focus on men as the future of Middle-Earth.
Lord of the Rings focuses its narrative primarily on the affairs of men, elves, and hobbits. Dwarves are a secluded race that lives in the mountains. As a result, Gimli is the only dwarf whose presence is really felt throughout the narrative. Gimli is an extremely important figure in Middle-earth.
Of these thirteen Dwarves, three die at the end of the novel in the Battle of the Five Armies: Thorín, Fili, and Kili. Ten survive. Of these ten, Glóin tells Frodo, seven remain at the side of Dáin, King Under the Mountain: Dwalin, Dori, Nori, Bifur, Bofur, Bombur, and Glóin himself.
Physically, Gimli was the strongest member of LOTR's Fellowship, and that's because Dwarves were the strongest race in Middle-earth. During Lord of the Rings' Council of Elrond, it was decided that Frodo would take Sauron's Ring to Mordor and destroy it in the fires of Mount Doom.
Though Gimli officially wins the kill count at the Battle of Helm's Deep, there is an argument that, in the films anyway, Legolas is the real winner due to the sheer numbers of Uruk-hai we see him fell during the battle – including all of those upon the huge siege ladder he sends crashing to the ground with a well- ...
They're not immortal. The Undying Lands do not confer immortality on mortals. This was the big lie that Sauron told to Ar-Pharazôn the Golden to persuade him to attack Valinor: that those who went there became immortal.
Although Gimli knew that Moria could be dangerous in the book, he did not know about Balin's death in The Lord of the Rings: The Fellowship of the Ring movie possibly due to slow communication and Dwarves' perception of time.
It suggests this may have been a philological joke on Tolkien's part. Dwarves were long-lived, with a lifespan of some 250 years. They breed slowly, for no more than a third of them are female, and not all marry.
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.
Gimli is 139 during the events of The Lord of the Rings. Dwarves have an average lifespan of 250 years; thus, being young and strong, he was selected by Elrond to represent the Dwarves as part of Frodo's company.
So when she allows this incredible rarity to Gimli, she essentially gives him the three hairs that Feanor demanded of her, because she has looked into his soul and found that he has a good heart and that he desires them for nothing more than to treasure the beautiful days he spent in her lands.
She doesn't give him one, but three. Three strands of her hair. This is why Legolas is smiling in that scene when Gimli tells him what Galadriel's gift was. He's smiling because he knows the significance.
After Thorin's death, his cousin Dáin II Ironfoot of the Iron Hills became king of Durin's folk; and when news reached Durin's folk in the Ered Luin that Erebor was retaken, it is believed that most of them moved to the Lonely Mountain. Therefore, Thorin's hall became a sub-realm of Durin's folk.
While in the book Fíli and Kíli are said to be the youngest of the thirteen Dwarves in Thorin's company by at least fifty years, Ori is instead the youngest within The Hobbit films. His weapon is a slingshot; In The Fellowship of the Ring, his skeleton is shown holding the Book of Mazarbul beside Balin's tomb.
All he knew was that Moria had been evacuated because of something called Durin's Bane, and that it still lurks inside. And while he does know that Orcs attacked the Dwarven kingdom, it was many years ago, and so he hoped they were gone.
The longest living Dwarf was Dwalin who lived to become 340 years old, 80 years older than the second oldest Dwarf. Hobbits lived a very quiet and uneventful life compared to other races and since they had the habit of drawing their family tree their age distribution is fairly narrow.
Gandalf's age is impossible to determine, but he's likely existed for at least 10,000 years, making him much older than Legolas.
The Ents appear in The Lord of the Rings as ancient shepherds of the forest and allies of the free peoples of Middle-earth during the War of the Ring. The Ent who figures most prominently in the book is Treebeard, who is called the oldest creature in Middle-earth (a description also given to Tom Bombadil).
It told how Balin discovered Durin's Axe, and established a small colony, but it was overrun by orcs and Balin was killed by an orc archer in Dimrill Dale. Thus he died in the same place as his father, having been self-proclaimed Lord of Moria for less than five years.
Thrór was murdered as he entered the East-gate of Moria, leading to the War of the Dwarves and Orcs. Even after the end of the War, many Dwarves refused to reclaim Moria, partially because of the Durin's Bane. Years later however, the Dwarves managed to reclaim the Lonely Mountain.
Their language of Khuzdul is a secret that they don't share with outsiders, so writing it on a public door wouldn't have been allowed. As such, the choice to have Moria's password be in Elvish both reflects the friendship between the two peoples and Dwarven culture.
Eventually, Legolas came to Ithilien with some of his people, with his father's leave, to live out his remaining time in Middle-earth helping to restore the devastatedforests of that war-ravaged land.
Though the Undying Lands can be viewed as heaven, going there doesn't mean death. It is a paradise, yes, but it is not necessarily the end. As far as we know, those elves go on to lead beautiful immortal lives in the Undying Lands.
Gimli's attempted destruction of the One Ring was most likely added to visually demonstrate to viewers that the ring could only be destroyed by the fires of Mount Doom, but it unintentionally became one of the most important moments for one of the trilogy's heroes.
