trying to find a fic in a fit of nostalgia

hey all 2 of my followers im not even in this shit anymore but i remembered this one fucking amazing fic and i can't find it anywhere??? it was a series and it went really deep into equestria's history and i think there was a focus on rainbow dash and her ancestry (her wings got ripped off at some point)? idk man it mightve been deleted but that was my 8th grade self's Golden Standard of Fic and im feeling nostalgic. anyone got any idea what fic it was?
