Dwalin
Dwalin was the first dwarf to enter Bilbo's home.
He had a blue beard tucked into a golden belt, with
very bright eyes under the dark-green hood of a hooded cloak.
He was having tea with Bilbo and they were on the
third cake, when his brother, Balin, came next, also alone. They seemed
to get along well, chatting at the table like old friends.
Of the thirteen dwarves, four came to help Bilbo
serve the food the moment he wished for it aloud: Balin and Dwalin with
Fili and Kili.
