Hi! So I need help locating a fic, it's stukony centered in middle aged au, abo dinamics and as far I can remember Sarah Roger's is queen mother, Steve is the future king and bucky is his mate, when they go to war with the Stark kingdom that is under Obie tiranical rule they find Tony the prince alone in the castle no servants or anyone there just him waiting for them in the trone room and of course they take him with them and Tony is supposed to be Bucky and Steve Omega.
