Fíli

*Fíli and Kíli were nephews of Thorin, who was the elder brother of their mother, Dís. They were also nephews of Frerin, grandsons of Thráin II, and great-grandsons of Thrór. Fíli's most distinguishing feature was his long nose, the longest of any of the Dwarves in Thorin's company.[2]

As the youngest Dwarves, Fíli and Kíli had the sharpest eyes, and were often sent scouting or searching. It was they that found the Front Porch while in the Misty Mountains.[3]

With the other Dwarves, Fíli and Kíli encountered spiders and were later imprisoned by the Elvenking Thranduil.[4] They escaped the cells thanks to Bilbo, traveling down the river in barrels until they reached Lake-town.[5] The brothers accompanied Thorin and Bilbo to Lake-town while the others rested by the river.[6]

At the feet of the Lonely Mountain, Fíli and Kíli scouted Ravenhill and found the Front Gate with Balin and Bilbo. Also, with Bilbo, they found the side-door leading into the mountain.
Both brothers were killed while defending the mortally wounded Thorin Oakenshield in the Battle of Five Armies, and all three were later buried with honor.
When Kíli is surrounded by several Spiders and is left with no weapons to defend himself, Elves, led by Legolas and Tauriel, arrive and rescue Kíli from the spiders. Later, Tauriel notices Kíli holding a small talisman and inquires about it. He tells her that the talisman reminds him of the promise to return he made to his mother, Dís. They begin to talk, with Tauriel telling of her Elven love for the stars, and Kíli telling of the time he saw a great blood-moon (presumably a lunar eclipse), while Legolas listens unobserved from the shadows.

Soon the Company is rescued by Bilbo, using barrels from the wine cellars to escape. In the river they are stopped by the Elven-guard, who swing shut a portcullis across a narrow place in the river to block their passage, when suddenly both Elves and Dwarves are attacked by Bolg and his Orc troops*
