I remember reading this story a while ago back in 2013. Anyway, the plot is this:

The Elements of Harmony are called up to fight against some evil, and during that process, they end up time traveling back to the past. Princess Celestia and Luna cannot find a spell to rescue them from their eternal imprisonment in the past, so the Mane Six eventually live out their lives in the past.

I knew that one of the tags was "sad" and I believe the title was in Latin. I just need to know what this story is, because I'm trying to find it everywhere.

Was it Que Sera Sera?

Yes.

Thank you very much. Its pretty hard to find on this site, especially with the odd title. I can finally re-read the story.
