It was called To Be Free From Pasts and Shadows by tyger-me-happy. Boromir is the "bad guy," Legolas is the slave, and Aragorn is the "good guy" if you will.
lothy even recced it, many moons ago. Someone made a parody of it and I wonder if/suppose that's why the author took it offline again, even though I really liked it. :( Does anyone have a copy of the fic, or any leads on where the author is now? Even a new author penname or titles of other stories they wrote would be helpful in tracking them down! There's a lot I can do with that in a Google/Ao3 search. I'd love to contact them to get a copy for my own personal use.
Many thanks in advance!
(P.S.: And yes, this is a "throw away" journal because I'm still a little embarrassed about liking slavefic... even though I clearly do like it a lot, lol! >_>; )
