I'd love to read a fill with Arthur Baggins, hobbit, being dragged along by a company of dwarves. And when they get to the Lonely Mountain and he confronts Smaug, he finds a dragon egg...which hatches into a baby dragon - Alfred - who promptly decides Arthur is his 'special person'.

The rest, like if you leave everyone else canon Hobbit characters, or fill their places with other characters, up to author-anon!
