This story is a sequel to Days of Wasp and Spider

Believed dead by their creators, the ponies that will become Celestia and Luna have broken their mental conditioning and escaped into the wilderness. Here they plan the revolution that will free all ponykind, knowing that it is only a matter of time before their ruse is discovered.

Back in their underground arcologies, the ponies' erstwhile masters deal with the consequences of the escape, all the while unaware that something lurking at the bottom of space-time wants them all dead.

Before Luna became Nightmare Moon, there was Discord, and before there was Discord there was Sombra, the tyrant King of the North. He was the only foe who was vanquished without the Elements, but by the Two Sisters with divine magic all their own. They lost a city; it was taken by the mad king's magic.

After years among the three pony tribes, the Two Sisters fight their first great foe all by themselves: King Sombra, the tyrant King of the Crystal Empire. Nothing goes as planned, everything, and everypony are not as they seem.

The price for this oversight is the future.

A few years after Luna's return it seems that Equestria will finally know an era of peace and appears to be on the verge of a new renaissance. Ponies are blithely happy, as they are often.

Luna is recovering, and happier than she's been a long, long time.

Celestia is miserable. She's faced with unexpected changes, like always. It never really mattered until she was faced with something (or rather somepony) she wasn't sure if she could cope with, and everything that came with him.

Now, it feels like she is watching the world fall apart. Her world.

Spartans never die, they're just missing in action. This has never been more true for Jorge-052 as, after activating the slipspace drive that was supposed to kill him, he is instead flung into a strange world where war is but a distant memory. Will the aging soldier be able to adapt to this new peaceful planet? Or will his only salvation be found in finding a way back to his own chaotic universe?

It has been a few months since Twilight and her friends went to help save the Crystal Empire, and Twilight had to use dark magic to find the Heart. And ever since she got back, Twilight's been acting strange spending most of her time muttering to herself, hearing voices, and locking herself up in her now 'off limits' lab basement.

P.S. seeing how many corrupted twilight fics there are, I'm sorry if anything I write is from your stories.

SF (canon species only; no humans) Ponies were magically and genetically engineered to be the perfect servitor race. They are powerful, adaptable, intelligent and completely under the control of their creators. A laboratory accident frees one such pony from her mental chains, but how can one mare save herself and the rest of her kind if she doesn't even know she's a slave?
This is not the Equestria you know and these are not your little ponies... not yet, anyway.

A Soot-Covered World, book 1.

After being introduced to Dark Magic, Twilight has used it to her advantage multiple times(using it for Zecora's potion, finding the Crystal heart). Twilight starts to experiment with it, causing her to grow obsessed. She's noticed that its beginning to change her. She must stop herself from succumbing to the darkness before her friends loose her forever.

Princess Celestia has been keeping a dark secret from her subjects for a very long time.

It's not an easy truth to tell, but if anyone can accept her after learning it, it will surely be her most faithful student.

Would you rather die, or become a slave to darkness?

NB: This is a continuation of a comic dub I found on youtube. You can find the link here and there. You MUST watch it before reading this, otherwise it won't make any sense haha. Also, I'm yet to come up with a decent description of this so it may change at some point, as will the tags.
This takes place in the same universe as the IDW Comics that featured Rarity turning into Nightmare Rarity.
Dialogue sentences that appear in italic is the conglomerated voice that gets mentioned, so don't get it confused with normal dialogue or words that appear in italic in the middle of other sentences.

When Pinkie Pie breaks into the Mentally Unstable Wing of Ponyville Hospital, she finds out that everything is not what it seems.
