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.

It was just one slurp that started it. That heavenly taste, that powerful punch to the gut! Raven was lost before she even knew what happened, carried away on waves of caffeine and power.

Luna should guard her coffee more carefully.

Done for a patron.

Seven years. For seven years she was neglected. In that time, she was underpowered, defeated by a nag in the moon, defeated by an evil bug roach, a victim to tentacle vines, defeated again by the same evil bug roach as before, as well as many other slights and insults in between.

All she wanted was one episode of her own, one to show her glorious personality in all of its radiant glory. Unfortunately, it was not to be. Her impressive record as the longest living and serving monarch (now diarch, lots of love to dear, dear Little Luna), brokering peace and prosperity the likes of which no other nation could hold a candle to! Or a sun, for that matter.

Time to do something about that.

The ponies of Ponyville grew fearful of a being that lived among them. Wielding the weapons of his people, will they finally band together and claim victory over him once and for all? Or be shot down in defeat?

There are a number of compounds the human body is incapable of synthesizing; these are found only in red meat. To save a dying human, Twilight asks her friends - except for Fluttershy - for advice.

My name is Twilight Sprinkle, and my passion is donuts—from the delicate morsels I serve at elegant cocktail parties to the hearty pastries enjoyed by hard-working ponies who get up early. I don’t have friends, I don’t have books, and I sure as the sun don’t have any wings. I don’t care whether you’re here for revenge, for romance, or for a favor. My name is Twilight Sprinkle and I’m not who you think I am, so either buy a donut or get the hay out of my store!

The most wanted villain in recent memory, having been captured by Starlight Glimmer, has been requested by Cadence to be put up for redemption.

The catch?

Chrysalis has to choose a husband from a list the Princess of Love has crafted after three days and two (mostly) sleepless nights of coffee fueled discussion. Energy drinks were consumed. Donuts suffered inglorious fates. Prince Blueblood was put in charge while the sisters delt with lending a hoof in deciding the fallen changeling queen's fate.

Her other choices?

Celestia wants her turned to stone.

Luna wants to send her to Tartarus.

Stone, Tartarus, or marriage. Those are her choices.

Cadence won't let her choose the first two.

Dear Aggy. A popular advice column loved by many. Many believe her to be one of the most amazing mares to have ever lived, and she offers the most sensible advice about love. Some ponies even believe that it must be Princess Cadance writing from a pseudonym.

Nopony would ever believe the truth, that Miss Aggy is actually Maud's pet rock, Boulder. Of course, being a rock, he needs a little help from Maud to answer his mail and write his responses.

An entry in the Weedverse?

Dear Aggy needs your letters!

This story is a sequel to Metroid Equis

With the culmination of events on the BSL Research Station, Samus Aran is finally able to come back to Equestria, Planet Equis; to come back home. Much has changed in her absence, but it is still the friendly, peaceful, welcoming planet and nation that she left behind two and a half years prior. With the Space Pirate threat neutralized and the secret, illegal Metroid militarization programs destroyed, it appears that Samus can finally take another massive breather with her friends and enjoy some well-deserved rest, recovery, and relaxation. The galaxy is finally at peace.

At least... for a short while.

A new enemy, one much closer to home, soon rears its head, threatening all of Equestria and Equis with complete and utter annihilation. Their mission: revenge. Samus will fight with all of her being alongside her allies against an enemy who would like nothing more than to see all that she holds dear, including her home planet, completely razed. In so doing, her cunning, ever determined enemies unleash a weapon so unexpected, so eerily familiar yet horrifically foreign that even Samus herself just might prefer the late Ridley or the SA-X...

This story is a sequel to How to Hug a Five-Hundred-Foot Tall Dragon

It was supposed to be a routine flight over the desert, just a relaxing trip to stretch his wings out. He'd done it a thousand times before.

This time, it wasn't so routine.

Sex tag is for innuendo. No clop.

Part of the Hellpiercer 'verse, but knowledge of that story is not required. Reading the direct prequel How to Hug a Five-Hundred-Foot Tall Dragon is advisable, however.
