An AU where Dwalin is devastated by the deaths of Thorin, Kili and Fili, and the departure of his brother, Balin, to Moria with Ori. He’s so upset that he decides to retire and leave with his viola for dwarf villages, singing the Bard's Song to little dwarves and anyone who wants to hear it. In one of the villages he meets a dwarf woman, falls in love, brings him happiness, and moves with her to Blue Mountains where he reigns on behalf of Thorin. He marries her, lives the rest of his days in the Blue Mountains and has 10 children.
