Hi, going crazy looking for this. It is an AU follow up to "Turn of the Wheel" series by Gekizetsu. The follow up itself, I believe, is written by another author. In it, Dean never loses his wings and the elementals are still at war with each other. It is post apocalyptic in tone, I think. Decidedly slash. Sound familiar?

I was wrong before, the author is Gekizetsu. Great story, thanks for the help.
