In the first comment fic meme, there were two beautiful ficlets set in an AU in which the rebellion never happened and Stannis took the black (http://gotexchange-mod.livejournal.com/829.html?thread=16189#t16189). Tbh, I'd just love to see more fic written in that verse because I find it incredibly interesting, the conflicts between Night's Watch!Stannis and young bastard Lord Commander Jon.
