You've discovered Alter!Series! ^_____^ (Random aside plug since you are reading A!S and seem to be open with your pairings: If you follow the links through the non-cannon section there, you'll find 'House of Smex' houseofsmex which is the home of the RoyxEdxAlxRizaxMasuta OT5!)

And while we are plugging comms faulty_wish is another great joint AU, with lots of fun twists and Ed torture. :3
