"So, what's this big idea of yours," a muscular menacing centaur, asked.
Standing atop the old ruins of a once grand building a trio of creatures young and old, looked beyond the sea of trees below them to see a billow of smoke and a plume of fire dancing before them.

To the right of the centaur was a small filly, her mane frazzled and limp as the rain-drenched it, it's color seemingly gone as the slight tint of blue could hardly be seen by the dirt and grime within it.
She smiled at the red centaur with an innocent grin, "Like I said Mr. Tirek," she began, "my plan is like a game of chess-" the young filly looked down at the same bright lights that emitted from a certain royal city, the sounds of roaring celebration emitting as well, "and like a good game of chess we have to take out the pawns if we ever want to get closer to the Queen..."

There was a level for criminals in Equestria; if they commit crimes against the public they would be sent to jail or prison, if they tried to harm, or kill, Celestia or any of her other royal delegates or family, they would be sent to a dungeon in the recesses of the Cantorlot castle, or face exile. But there was a special place for those that did both, and had magical prowesses that matched up to beings like Celestia, Luna, and even the now reformed Discord; a place far, far away from the monarch's subjects where they could no longer do any harm. That special little place was Tartarus, a small prison-like holding hall that could be described as, extreme detention by young colts and fillies who have heard of the place.

Rather than normal prison cells, most of these dangerous creatures we placed in animal cages, which was fitting considering most of the inhabitants of the cells were animal-like creatures

Well, all except one; in the very back of the prison, guarded by a black Cerberus, a red centaur about the same height as Celestia sighed heavily with an annoyed look. Tirek, who nearly consumed all of the magic in Equestria and had a physique of a muscular greek-god, was now reduced to living in a small cage and had the appearance of a withering old man. It had almost been three and a half years since Twilight Sparkle and her friends defeated him, he was so close to finally taking over this world but, like many other villains before him, he had his plans halted once again by the Elements of Harmony.

Although this would have greatly annoyed the centaur, that memory wasn't his current thought of annoyance; to the right of Tirek was a small cage that, surprisingly, had a small, cute, pink furred filly who hummed a tune with a happy smile. This innocent looking filly was CozyGlow she had a smile the could warm anyone's heart, was a bit of a ditz, but would always try to ratify her mistakes. But that was just an act, the moment you turned your back, her large doughy eyes and an innocent smile would be replaced with a more menacing, almost demented smile.

As for why such a filly was placed in Tartarus rather than some sort of juvenile center, well, let's just say that attempting to take-away all magic from Equestria is a big no-no.

The young filly continued humming, much to the annoyance of the skinny centaur, as she bobbed her head from side to side.

"Cozy Glow" Tirek called to the humming filly, however, she continued to hum completely ignoring the greatly annoyed centaur, "Cozy," he called again in a louder volume, once again, no response, "Cozy!" he yelled in irritation, the filly continued to hum.

Tirek's face had reddened, even more than usual, at the blatant ignorance of the small filly, "Listen to me you little imp, If you continue to ignore me, I'll flay your skin, and tear out your nerves!" For about the fourth time, she ignored him, realizing the uselessness of continuing this tirade, he ceased his yelling and turned away from the filly.
Just as he did that, the fillies eye's slowly opened, letting out a long yawn as well. She turned to the frustrated centaur with a wide smile, "Good morning Mr. Tirek," she said happily.

"How can you tell the time of day, when there is not a window in this hellhole of a prison," he replied with a sigh, "Also, It's Lord Tirek"

Cozy placed a hoof on her chin, "Lord huh," she parroted. The small filly giggled at the assertion, "For someone like you I don't think that title fits you anymore."

"And what is that supposed to mean!?" he growled, "I'm the most powerful being in this worthless world-"
"You, were, the most powerful being in this worthless world," Cozy corrected, causing the skinny Centaur to glare at the filly, "Oh calm down Mr. Tirek, I was just trying to pass the time."
"Why," he questioned, "You do understand we are here for all eternity right? There is no point in doing something so useless"

"You say that like my plan is over,"

Tirek, at the sound of those words, looked over to the small filly, "What do you mean?"

Cozy turned her head away from the red centaur and stared at the tall double doors that led to the outside, "Everything was going according to plan," she began, "Even if the elements somehow found a way out of this place, all the worlds magic would have been gone-" Cozy furrowed her brow, as she began to remember a certain group of six "But those six cogs, ruined it, had everything went right I would have been ruling this place with an iron hoof and everyone, even non-ponies, would have been under my control. But those, cysts," her voice became oddly deeper and emotionless "because of them, all that planning all that work of having to kiss up to uptight, arrogant, ponies-" suddenly, Cozy's expression changed back to her usual happy, cutesy expression, placing both of her hooves over her cheeks "Everything went exactly as I expected!"

Tirek continued to stare at the filly, somewhat confused by her words, "I don't follow"

Cozy cleared her throat before she began her explanation "You see Mr. Tirek, during my plan over at the academy I had formulated two alternate ones; I'll be honest, I was very confident in my planning, but I just wanted to create some...insurance, in case the other one fell through-" she proceeded to look around the room, "and by the looks of things, it seems that phase one of my alternate plan is going to begin!"

After hearing her explanation, the former lord, looked at the filly with a doubtful expression, "And how do you expect we go about that?" he commented, "As I have stated before, we are stuck here, I doubt you could account for such an escape from a place such as this."

Rather than reply to centaur's remark, Cozy proceeded to tear off a piece of her...fur? Underneath the tape-like fur cover, there were two small bottles: a small brown-tinted glass bottle, and a small, clear glass bottle. Tirek cocked his eyebrows in suspicion at what Cozy was doing but was soon answered when the small filly proceeded to unscrew the top of the brown glass bottle and drizzle the substance from the bottle onto one of the bars, and in an instant, the bar slowly began to corrode stopping only half-way and flattening the corroded part, which allowed Cozy to safely exit the cage with ease.

Tirek stared at the filly with a stunned expression.

"You know, it's a good thing that the royal guards are so incompetent," the filly walked over to the centaur's cage and began to sprinkle a bit of the same substance that melted the bar of her cage, doing the same to Tirek's cage.
Although they did not entirely melt away the bars were weak enough for the centaur to break the cage open, and exit his cage.

With a slight look of delight, Tirek proceeds to stretch his arms and legs out with a large grin, "Well, I must say," Tirek began, finishing up his stretches, "you certainly are full of surprises."
"What can I say, like a game of chess you have to think about alternate routes before going for the easiest one," after saying that, the small filly pulled out yet another surprise.

"A spoon," Tirek questioned, his eyebrow cocked, "what are you planning to do with that, exactly?"
Once again, rather than answer the centaur, Cozy lifted herself into the air and quietly flew over the three-headed guard-dog, as to not wake them up, and landed next to a sleeping cockatrice.

Cozy then proceeded to poke the beast with the end of the utensil and said beast immediately awoke and went into defense mode.

Cozy stared down at the animal with a demented look, "Time for phase two!" Cozy grabbed the rooster-dragon by the neck and pushed it down onto the ground, its head sticking out of the cage right under the filly, who had raised her spoon high above the beast's head.
