I'm looking for a specific fic I read a while ago, like at least a year ago I think, that's essentially canon movie-verse except that it eventually comes out that Tony has some pseudo-magical ability... he's a Smith or a Maker or... I'm not sure what it was called, but anything he makes is actually an item of power. Tony is still Tony so he's sort of annoyed by the idea that magic has anything to do with what he does. This all becomes important when they figure out why Loki asked Tony to make him a gift of a Starkphone earlier in the fic.
Please please please can anyone help, I'm desperate!
ETA: Resolved! The series I was looking for was The Saga of Hug Fortress, which... I'd like to fervently recommend, but it's a WIP that is unlikely to ever be finished. ;_;
Thanks for your help!
