Twilight has the power to change the biological structure of anypony, or anydragon into something else. And, after seeing Rarity fall over other stallions, Spike the dragon wants Twilight to change him into a pony so that he could finally have a chance to be with the mare of his dreams. She gives in and casts a spell on Spike, turning him into a pony. However, this spell is temporary, unless Spike gets his cutie mark within three days.

But becoming a pony for the sake of Rarity comes at a price; Twilight Sparkle will lose her one and only number one assistant, something that is dear to both her and Spike.

My family was killed, I have lost the last person I dearly cared about, and now the Royal Guard, the Ponies of Ponyville, and Celestia are out to kill me just because of me being a pony-changling hybrid! What else do I have to lose? I could just end it all and be done with it! But I can't if there is the slightest chance of me seeing Luna again, then I must do what I can to see her again! Even if I must wait for as long as she is banished then I must wait for her. Don't worry princss, I'll be seeing you soon....

Celestia and Luna have a argument so big, they aren't even called Sisters anymore. Now Equestria is joining the army to vote who is the best ruler: Celestia, or Luna? War is among us, and Luna has found a way into the human world...as well as Celestia. Now with a huge crossover with humans, video games, and anything else you can think of, the war will get bigger and stronger. Here's the bad part: when the Mane Six tried to join the army to stop their distruction, they are put on different sides, and slowly losing their friendship.

Will the Mane Six be able to fix their friendship and stop war once and for all? Will the Solar Empire win the war? Will the New Lunar Republic win this war? And who else is coming to battle? Read this amazing and very long story as you discover...who wins.

YUP! This means, put your OC's bronies, because this...is going to be a very...very huge story. Featuring any cartoon that comes into the story. When you see anything that has green, that means you get to pick which is a good idea. Do you vote for the Solar...or Lunar...or any other team that appears?

The New Lunar Republic are fighting back against the Solar Empire, secretly and evasive. The fight between who should be the true leader of Equestria is causing an uproar from civilians. Who will become the victor whilst the defeated are exiled or maybe even killed? Maybe both sides will face an untimely loss and none of them win or lose? Inspired to write this from the cover art.

After finding out about the disappearance of Flurry Heart, Shining and Twilight can only guess someone fillynapped her.
But who would do such a thing?
A past villain?
A random monster?
A new foe?
Only one thing's for certain.
They will find her, no matter how awkward it might get.

When Twilight loses control of her magic, she finds herself in the realm of the the eternally damned, Tartarus. In order to survive she is forced to learn and change. However, when Twilight finally escaped from Tartarus, how will Equestria deal with a Twilight who has been forged in hellfire?

Author's Note: I want to point out that the Dark and Gore tags are not all consuming. They are there only by necessity. There are going to be some dark material in here, but nothing grim.

On the same note, Twilight is the only anthro in the story, and there is an in-story reason for it, so don't let that big nasty Anthro tag scare you.

One final thing. It has been some time since I've done any real work on this story. To make clear how long, this portion of the author note was added July 5th, 2019. This story is currently sitting in that little area between "Hiatus" and "Cancelled". Time will tell if I revitalize it.

The World of Tartarus Forged.

Although he may or may not have been expressly forbidden to, Star Swirl the Bearded (who had not quite grown into his facial hair at the time) has on occasion peered into the future. He beheld the return of Nightmare Moon, of Discord, of Sombra, and worst of all, to him, he beheld the loneliness of his immortal Tutor and Master, Celestia.

Then, he saw a way to fix it all.

...so long as he doesn't get caught.

When a drowning Twilight Sparkle is pulled from the ocean by a group of salvagers, she receives news that changes her life: she is now two-thousand years into the future, and Equestria no longer exists. Instead, there is the kingdom of Centuria, ruled over by the seemingly immortal tyrant, King Ganymede.

In this new world, unicorns are a rare sight and advanced technology is shunned by the general public. Twilight finds allies in Kevrana, a salvager with a heart of gold, and Hadran, Kevrana's suspicious and cynical brother. As a war brews in the land, Twilight, with only her new friends and legends of a strange place called the Vale to guide her, must set out to unravel the mystery of how she came to be in the future, and whether or not she can ever return to her own time.

Shout out to MarioDS01 for letting me use the idea!

There were many things Chrysalis was prepared to lose. Her hive, her children, and her crown were not amongst those things. Fleeing her old home, with no one to turn to and nowhere to feed, she stumbles across a town she didn't know existed.

From serendipity hatches an opportunity. From opportunity, progress. And perhaps, one day, even redemption. It is a long way off. There is a lot for her to confront, both in her past and future. But she has a lot of time in exile.
