Looking for "Tony moves to the moon" fic
I'm looking for a fic on AO3 I read a long while back, where Tony (After the civil war?) sells off Stark Industries and dissapears. When Thanos attacks earth and earths heroes are defending, he appears and after they win its then revealed that he moved to the moon, created a home for himself there and created more "scifi" like creations like a portal (That he also used to get to the battlefield?) and other Star Trek inspired inventions
