I need help finding a story again. Two, this time. One where Twilight tries to rescue a journal from a fire but is stopped by Rainbow. After, she runs away for a few years before returning with a group of strange ponies.
The other is where Twilight somehow finds herself in a place beyond Equestria, I think with her horn broken and the creatures and ponies there protect Equestria.
CURSE MY TERRIBLE MEMORY!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

How's it going, everypony? I'm looking for a certain story and I can't remember what it's called. I know that it's about Twilight and Flash starting their own kingdom after the wedding in Canterlot and everyone thinks she's dead.
It starts with Flash a freeing with her suspicions about Cadence, then they go to the library and end up leaving. But I CAN'T REMEMBER THE NAME!!!!!!!! HEEEEEEELP MEEEEEEE!!!!!!!!!!!!!!! If you know, or think you know, can you message the link? I'd be so grateful.

I need some ideas for what to do with Sunset In Mother Nightmare. Just message me or comment if you have any ideas.
