He didn't deserve another chance after what he did, but he got one. He got the forgiveness he never expected, from the last pony he ever expected to get it from. In gratitude to her, he writes her a letter, thanking her and her friends for everything.
His mind and heart laid bare both to himself and those who read it. He has the freedom he truly wanted.
But you know what? Just a letter isn't enough. No, he must tell her himself.

https://www.fimfiction.net/story/143483/a-draconequus-guide-to-immortality
At her coronation after-party, Twilight gets a little freaked out at the prospect of growing into her new life, especially one specific aspect of it. She knows better than anyone that talking her problems over with a friend can help tremendously, but she doesn't have many friends with whom she'd be comfortable talking about this particular problem, let alone ones who would really understand what she's going through.
...unless she broadens her definition of "friend."

Forever Young by Hyperexponential
https://www.fimfiction.net/story/99216/forever-young
Nopony ever said the friendship between Fluttershy and Discord would be an easy one. The difference in their life expectancies doesn’t help, but that’s a problem Discord can fix with a snap of the talons—that is, until Fluttershy finds out.

Why Me? by Viking ZX
https://www.fimfiction.net/story/207113/why-me
So, four days ago, Tirek brought Equestria to its knees—with my help—only to turn on me—which I really should have seen coming, but that's hindsight for you. And then some stuff happened involving—of course—rainbows, ugh, and now I'm here. Helping pay off my debt to the nation by fixing things which may or may not have been broken by me in the first place, like a good draconequus should.
Problem is, doctor, I've been finding myself preoccupied as of late, and I really just can't see why...

Discord's Day by SpinelStride
https://www.fimfiction.net/story/185927/discords-day
Discord has a problem. He has a tendency to not think through his actions all that well, poor impulse control, and no ability to figure out how others will feel about what he does. Even with a friend helping him, sooner or later he's going to do something that'll get him stoned or hit with a reforming spell or whatnot. So what's he to do? Ask the smartest pony in Equestria for a solution, of course!
He probably wasn't expecting to get "Have Celestia let you rule Equestria again" for a response.
No one else was probably expecting to enjoy it.

What he didn't know was that in this future, he has been reformed and the ponies there think he's somehow lost his memory and are determined to refriend him. Gag!
Meanwhile, the reformed Discord is teleported to the past, facing very hostile ponies and a world of Chaos his past counterpart had created. Chaos is a wonderful thing and he was all up for having some fun but what was the point if he had nopony to share it with?

https://www.fimfiction.net/story/167397/order-chaos-chaos-ordered
Bored one evening, Discord suggests to Celestia that they spice things up by seeing who's best at doing the other's job: he'll handle keeping things harmonious, and she'll be there to throw a big ol' spoonful of chaos into the mix whenever she feels like it. To his surprise, she agrees to do it. He's certain he's got this one in the bag—after all, how hard can something as boring as harmony be?
He shouldn't have underestimated his opponent.
Discord the Archduke by AkumaKami64
https://www.fimfiction.net/story/373858/discord-the-archduke
Discord never betrayed Equestria for Tirek, aiding in returning the magic to all the drained unicorns. As a result, Celestia deems him ready of a "small" gift: The Archduchy of the Everfree, technically making him the highest noble under the princesses.
Naturally, this shocks everypony, including Discord himself. Now of course his lands will some have some chaotic magic and strange laws in effect, but that doesn't mean he doesn't take the noble thing a little seriously. Why is anypony's guess, but it'll be entertaining to watch.

Reformation Buddies by Metool Bard
https://www.fimfiction.net/story/229060/reformation-buddies
While lounging around Twilight's castle and airing some friendship-related grievances, Discord stumbles across a magic book containing letters from an inter-dimensional pen pal. As it just so happens, this pen pal also had sinister designs for Equestria, but was quashed by the Elements of Harmony. What's more, she's made amends since that day, and she's now Twilight's friendship student. Eager to bond with someone who can relate to him on a personal level and grow into a better draconequus, Discord packs his bags and heads off to the human world with Twilight's semi-blessing. His mission: Befriend Sunset Shimmer.
However, his plan has a bit of a snag. See, Sunset hasn't been keeping up with Equestrian events, and she never got the memo about Discord turning over a new leaf. As such, she believes that his sudden appearance doesn't bode well for Equestria, Canterlot High, or herself. Not only this, but the Sirens are privy to Discord's return as well, and they see this as a golden opportunity to bounce back from their own recent defeat. Well, Adagio does, anyway. Sonata doesn't want to live in a world that makes no sense, and Aria would rather maintain what little dignity she has left by not getting involved (or so she claims).
So while Discord is trying to earn Sunset's trust and show her what a good friend he is now, Adagio is trying to get in on an evil scheme that doesn't exist. And while that is going on, Sonata is appealing to the Rainbooms behind Adagio's back, hoping that they'll make Discord go away. With so much miscommunication thrown into the mix, you just know that hijinks are inevitable. Good thing Aria made popcorn.

Now Tirek's imagination is stretched to its limit with just how horrible Tartarus can really become.

https://www.fimfiction.net/story/167698/dearest-fluttershy
Discord has lived for quite a long time. Centuries as a ruler, a millennium as a rock, years as a reformed draconequus, it all gets very tiring. A nap is exactly what he needs.

After all, any being that is truly important will live forever. Discord would never associate with anything less.
Definition of Insanity by LDSocrates

Mortal life is too short to hold a grudge for long. Immortal life is a different story. And even the greatest of the great have sore spots.
The Keepers of Discord by Hoopy McGee
https://www.fimfiction.net/story/25125/The-Keepers-of-Discord
You'd think that being trapped in stone would mean that, if nothing else, I could get some peace and quiet. Unfortunately, it seems that Celestia has other ideas.
She has appointed these ponies... these 'Keepers', as she calls them, to keep me entertained during my incarceration.
Honestly? I'd prefer the boredom.

One hundred eighty years before the first Nightmare Moon incident, the United Republic of Equestria is ruled by two prevailing parties and simply switches hooves between them every few years, as the citizens get more impatient and indecisive.
In the midst of the worst depression in Equestrian history, an egregious scandal befalls the United Party when the president of the country is found guilty at her trial following her impeachment, obliterating her and her party, and cementing any future victories of the Royal Party and their leader Princess Celestia.
Out of apathy, the United Party chooses Disce Cordis as their new leader - a strange draconequus with a piercing stare, an odd accent, and who can't even pronounce his opponent's name properly. He appears innocuous and ineffectual enough; but as his campaign goes on and he starts to gain more popularity, his strange speech and manner makes the citizens of Equestria suspect that, perhaps, the welfare of the Union isn't what is first and foremost in his mind.

He does cause a lot of chaos though, to the faithful student of Celestia, who had eagerly taken over the task of watching over and teaching Discord by giving him a home under her own roof, in the process hoping to learn more about his species, powers and motives but surprisingly learning much more about both himself and her head... Which puts her in pretty amusing situations most of the time.
An adventure of a silly one sided (???) love and a look into the heart of Twilight Sparkle.
