On a seemingly normal day, the Mane Six and Starlight are called to the castle and summoned by the map for the same incident - ponies are going missing all over Equestria, including a few of Celestia's elite guards. Nervous for their safety, specifically Fluttershy's, Discord tags along with them past White Tail Woods to investigate, and find some things that maybe should have stayed in the past.

Sidenote: I wrote this story A LONG TIME AGO before season 8 and 9 and pre-Cosmos comic arc. So it takes place before all that then.

Fluttercord if you squint. Kind of dark.

I'm also a filthy millennial who loves the found family trope and giving villains deep backstories, especially when they don't need them.

Discord, retired General for the Solar Army, lives alone in his apartment next to one that seems perpetually empty.

That is until Fluttershy moves in, and the two slowly become friends.

Just as they begin to border on something more, war comes back to Equestria's borders. Discord finds himself back in his former position, in peril and on the verge of having to reveal one of his deepest secrets. With Tirek on the rise and the country - the person he loves coming into danger's grip, he may have no choice. But there are secrets even deeper than his, ones that could change the tide of history.

(Death and Violence in later chapters and some flashback things, but nothing too crazy. Additionally, warnings for PTSD in later chapters as well)
(back at it again even though FCAAU is unfinished, but this has been sitting part written on my drive for two years now.)

MLP:FIM/Anastasia. Ten years ago, Lord Tirek attacked the Royal Family in Ponyville. While he was sent back to Tartarus, their family was broken by the loss of one of their Grand Duchesses, Fluttershy. Now, orphan Flowing Grace is on a journey to find out who she is, and who her family is, along with the help of Discord and Shining Armor. Fluttercord Shining/Cadance Celestia/Sombra.
