The short not spoilery version, Tony was a warlock, Steve was some sort of paladin or something, I think Bruce was a mage? There was a epic fight of some sort, I'm forgetting with who... maybe Loki? Natasha and Clint are there too. I forget if Thor was.
Tony was like the FEARED warlock but really it was just because he figured that since everyone believed that he was EVIL just for being a warlock, he might as well live up to it. He'd fled his 'clan' which were all mages I think? Steve had worked with Howard and there was angst there of course. He also had some sort of screwed up curse on him that the more Tony used his powers, the more they killed him? I think Tony had like, a village of misfit toys type place he managed. There was a happy ending with Steve taking Tony back to Howard after the epic battle and Howard cured him?
Oh yeah, Bruce was a werewolf and when everyone freaked out about it Tony defended him.
It's driving me nuts, anyone remember this fic/have it bookmarked anywhere?
