Set during the final chapter of the manga/the corresponding Brotherhood episode. Ed has made his offer to Truth. What if Truth refuses to accept it? Equivalent exchange. A toll must still be paid…
Not a death-fic, nor a parallel universe fic, or anything of that sort, though obviously an alternate ending of sorts. Be warned, though—said toll will be pretty brutal. Relationships will be implied if they do crop up, all pretty much canon.
