Tartarus. A burning plane of existence made to punish the damned and evil. And ruling over this pit of hellfire is Hades, Lord of the Dead and God of the Underworld. And while torturing souls and abusing his two minions Pain and Panic are always good fun, he's grown bored. With his plans to rule Olympus and destroy Hercules down the tube, he needs a new aspiration in his un-life. And since he needs to buy some groceries, Ponyville seems like the perfect place to go shopping. And maybe make an ally or two for his newest plan to take over Olympus. If he doesn't burn them all to a crisp and steal their souls first.

Twilight cast a spell and got herself turned into a filly. Luna has tricked Celestia into believing there is no cure, and now as Luna tries to 'find a cure' Celestia has to look after Twilight the Alicorn; filly version. And heaven knows Alicorns are not born often for a reason.

While walking home from work, through a thick blanket of snow you find a little filly name Luna laying in the snow. Would you take her home or leave her alone to freeze in the snow?

[Featured on EqD and FiM Fiction] It is that time again, the dreaded flu season. Not even Princess Celestia, the ruler of the sun and day, is safe from it. When Celestia contracts the flu, what pony could possibly nurse Celestia back to health? Why none other than her dear, loving sister of course! Enter Nurse Luna!

Between crazed guards, a palace staff desperate to please their rulers, and a crazed unicorn running around, no pony is safe from this madness.

This isn't where I belong. I left all this behind years ago, moved on with my life. But a mare from my past brought me back, and now she won't let me go. So I'm stuck here, trying to make the best of it with ponies that don't understand me, don't even like me. But when something moves in the darkness, and when things go wrong in the cold, dead night, they'll turn to me to try to set things right.

Why? Because once a police pony, always a police pony.

There is now a side-story: A Hard Day's Nightmare Night

When the day of Twilight's true destiny finally arrives, can Celestia fulfill an ancient promise to save Equestia's past, present, and future, even it means saying goodbye to Twilight forever? How can Celestia refuse her mother's last wish?

Discord lounges around Canterlot Castle without a thing to do. A reformed life has taken every surprise out of life. Until Celestia drops the bomb on him: He has a daughter. And what's more is that Celestia wants him to reunite with her with Twilight's help.

One night in Canterlot, a filly Twilight Sparkle gets kidnapped and her family needs to save her.

Or do they?

Special Thanks to asylum1388 and GeodesicDragon for proof reading.

Based on a certain Pixar Movie Scene.

Celestia wants Twilight and her friends to loosen up a little bit around her. Luna just wants to try the hard cider. During a surprise visit to Sweet Apple Acres at the tail end of cider season, Princess Luna has just a bit too much to drink, and when she makes a rather inappropriate joke, Twilight comes to the very uncomfortable realization that she has never seen Celestia excuse herself to use the restroom.

Do Alicorns always possess wings and horns? Or are they born 'normal', like the others? Are they really normal, anyways?

Celestia, Luna, and Cadence might not have always been this way. They had to earn their true colors.

This is at a time when they're still fillies, so no confusion is aroused.

New characters will be added upon being introduced in the story, so um... derp.
