If you'd care to toddle on off to here. It's a fic in three parts, and it will all be posted by New Year's. It's a bit heartening, a bit depressing, a bit family!angst, and a bit 'I really needed to figure out this head canon'. It's Arwen, with a lot of Elrond, Lindir, Aragorn, the twins, Bilbo and a bit of unconscious Frodo thrown in. And it's movie canon.
Now posted above on LJ!
