Dwalin

Dwalin was one of the Dwarves who traveled with Bilbo and Gandalf. Tolkien borrowed the name from Dvalin, a Dwarf from Norse mythology. Son of Fundin and younger brother of Balin, Dwalin is one of the least mentioned Dwarves in The Hobbit. He was the first Dwarf to arrive at Bag End. He wore a dark green hood and a golden belt and had a blue beard. Like his brother he plays the viol. Dwalin lent a green hood and cloak to Bilbo when they set out on their journey. After the death of Thorin, the halls in the Blue Mountains were claimed by the Dwarf Warlord Skrógrim, a Dourhand. Dwalin led the rebellion to take back Thorin's Halls and served as the king of the halls.

Dwalin supposedly died in Fourth Age 91 at the age of 340, very old even for a Dwarf.
