sgarecfinders | Looking for Dark Toned Mcshep fics and Great World Building (Reply)

I'm in a dark mood and therefore am looking for Dark toned John/Rodney fic. I'm very open on what causes this darkness. It can come from the characters or relationship itself or it can be the world around them. If it is the second I'd like it if the world building is well done.

The only thing I DON'T want is heavy drug addition. That bothers me. Anything else is fair game. Seriously. :D

I actually DO prefer happy endings, but in this case if it doesn't that is ok. Just warn me if isn't.

And while I'm at it, any other good recs you have with well done world building (light or dark) would be great. :D

Thank you so much ahead of time.
