I will admit I'm not caught up entirely but I'm a lil surprised no one has mentioned Godfeels by SarahZedig (and co)? Might be better to hold off until post-epilogues but the first part of the fic series was written pre-epilouges so... uuuh I'm thinking of what people haven't said... theres "The Collected Tales of Our Glorious Originators and Their Journeys Through Time Immemorial" by purplebard

and

okay so you have to work with me here bc it was abandoned because canon shit happened that made things a lil bit weeeiiird... but The Serendipity Gospels by urbanAnchorite... ooh TSG how I miss you so... don't listen to anyone who says The Locked Tomb series is a serial numbers filed off rewrite of TSG they are EXTREMELY different outside of like general writing style/humor and like duos being a thing and space conquest I guess but also not reaaaally?? But like you know something has its claws in you when years later you just go "damn... I wish we got to see how that would have resolved...."
