I've recently been enjoying two AU 'verses: The Sammy Verse (http://shangrilada.livejournal.com/7345.html) and the 3 Kings Verse (http://cosmic-medusa.livejournal.com/tag/3%20kings%20verse), and I'm wondering if there are other AU verses of similar caliber.  The writing and characterization in these stories are superb, and I think I've become a tiny bit spoiled.

I'm happy with most pairings or characters, show or RPF. I'm not picky about pairings as long as it's well-written, has believable characterization, and is compelling. I'm not looking for anything too dark.

In order to help with recs and tagging, I mostly read J2, Jeff/nearly anyone, wincest, Dean/Cas, Sam/Cas, I tend to prefer a sprinking of Gabriel. I'll also read het, but I know, the offerings are few and far between.

I think that covers it.  Thanks for any recs!

(Mods, I think I've covered it all in the tagging, and hopefully didn't go overboard.)
