I can appreciate the concept, and even the execution, of dark!fic, but I'm so much more a 'fluff' sort of person that I tend not to save links or info on any of the darker stuff, unless it's incredibly exceptional. There were a few that struck me, but I'm sure you've seen them as I'm a rather recently-joined member and they weren't really hard to find.

EDIT: More music is ALWAYS welcome. Skim back a bit and you'll see I've offered some, as have several others in the not too distant past. :)
