What if pony princesses were actually highly social carnivores?

What if a National Geographic team began following them around to film a documentary?

What if nopony saw anything unusual about this?

A metaphor about growing up. Or possibly a metaphor about living in a surveillance society. Or maybe just a very, very weird idea that needed to become a story.

It has been one of the closest guarded secrets of Canterlot's royalty. Deep in a specially constructed dungeon, surrounded by warding spells and powerful magic barriers, exists an enigma. Within a cage that could only be described as something out of a nightmare, it waits and watches all of Equestria. A creature that cannot age, is immune to disease, does not thirst nor hunger, and resists all injury. But, it also holds secrets and knowledge that could safeguard the kingdom. Its powers are frightening, but it is civil enough for debate when patience permits.

Princess Celestia has sought counsel with the creature before, enduring it making deal after deal for its services. The Princess walks a fine line when dealing with it, knowing full well anything could give it an advantage despite its imprisonment. She has had to go back on her word in these dealings, and from this a deep animosity between them has been born. It is a necessary evil as she is convinced this is a being capable of untold evil far and above anything Equestria has ever dreamed of. So long as it remains within the confines of its cell, her kingdom is made safe. So much magic has been woven to ensure that, there is little chance of escape.

So long as the magic holds, there is no danger. So long as the cage remains strong, the nameless creature stays enthralled in his cavernous dwelling. If that were to change--if the magic failed--not even the wisest could say. But one thing is assured, it does not bode well for Equestria.

Twilight Sparkle broke time when she got her cutie mark. Now Twilight and Sparkle are sisters from another time. Twilight is hailed as the potentially greatest light magician of all time, and already has a reputation as a hero by the time she goes to Ponyville. This isn't her story, not primarily.

Sparkle is an orphan - her dark magic killed her parents. She lives with her brother in Canterlot's industrial sector because they can't afford anything better. She can't leave either. She's a natural dark mage; while Sparkle won't go mad like Sombra, her reputation is hardly any better. Worse, the law doesn't see her as a good pony.

The fact that the dead don't stay dead around her, or that Thorn - Spike's double - is an undead, soul-eating abomination, are other matters altogether.

(Also has some Slice-of-Life, but fimfiction tags won't let me put it with Adventure.)

"My name is Sunset Shimmer, and there are two Twilight Sparkles who are both madly in love with me.

Please help."

Twilight tries on her first pair of glasses, and though she enjoys them, something goes wrong. Anypony who merely looks at her faints on the spot, and she must figure out why before the entire city of Canterlot is compromised.

Celestia said it herself, that Twilight Sparkle is no longer her student. While wandering around in the city of Canterlot one day, Her Highness stumbles upon Trixie's local stage show. To Her Highness, there seemed to be much potential behind the mere performer's act, and soon found it hard to resist taking Trixie under her wing.

Would Trixie even be up to the challenge?

Princess Celestia's School for Gifted Unicorns is the center of magical research in Equestria. Since Apple Bloom developed a love of potion making and an interest in the theory behind magic, she recognizes what an honor it would be to study there. But that would also mean being the only non-unicorn student to ever attend, leaving her friends and family, and moving to a strange city... and that's if she can pass an entrance exam designed to select the most magically gifted unicorns.

Spike has never wanted more than to be Twilight's number one assistant. But when Twilight points out that there's a pony right in front of him who needs an experienced assistant even more than she does, it means considering a life where he's making the most of his talents... but one without Twilight by his side.

For both of them, facing hard decisions are just part of growing up.

Celestia was always a "family mare". She always held up families as one of the greatest social institutions in the country. She is famously good with children. All of Equestria looks to her almost like some great parental figure. But for some reason she has always been childless herself.

Perhaps it's time to change that. She is, after all, married to the most wonderful mare she had ever known.
