"What do you want?"
The dark blue equine looked at you and simply rolled up your sleeve to reveal something on the back of your hand.
It was a six-pointed star, with two bats crossing each other beneath it, two bombs on the sides, a single smoke bomb on the top, and the anarchy symbol in the middle.
"I don't remember ever getting that..." You said, you don't even recall seeing it on your hand when you first got here.
"You got it after you knocked out roughly 20 guards and nearly killed about five." She paused, and looked you in the eye. "Here we call this a 'cutie mark.'"
Your face began to contort, and your lips began to curl and the incredibly ridiculous name.
"It symbolizes what one is good at."
You let out a bellowing laugh. Good at bats? Good at bombs? You knew how to use the damned things, but they weren't some hidden talent.
"Right. I can use a bat, make bombs, make smoke bombs, and cause anarchy. So what?" You say, turning your attention towards the exit.
"This is what I need you for, you see-" She was immediately cut off.
"Luna! Are you down there?"
The blue equine smacked her face with her hoof and drug it down. She then put on the best smiling poker face you have ever seen.
"Yes sister! Coming!"
With that, she left.
Flabbergasted and very confused, you slump down and sit on the floor. all of this is simply overwhelming to you. Odd, weird, talking ponies have taken you hostage. You really hope this is just some sick and twisted drug trip. You doubt that, but you really hope it is. You begin to think you simply went insane, so you're going to play along with these ponies for now. You wonder if they removed your weapons from you.
You feel around, and there are no bombs left in your coat. You sigh and feel around your pants. Nothing. You decided to give up hope and flop on your stomach a sharp pain shoots through body. You roll on your back and rip open your jacket.
How you missed it, you had no idea, but strapped in your hidden pocket were your bomb-making tools and a small bomb left. Inside also was a note, you pulled it out and read it in your head.
Use this for your escape, the gate should be open.
~Your savior
You look at the bomb. If you used it now you would blow the chain off along with half your body. Apparently that's what these tools were for. You were about to begin working on the bomb when loud steps began descending the stairs, panicking, you stuff everything back in the jacket.
The tall white one walked down, giving the worst evil eye you've ever seen.
"My sister tells me you are not a threat, simply scared. I must insist that nopony in the castle ever had the intention of hurting you, but you brought that upon yourself."
She sighed. Clearly this was not how she wanted to start the conversation.
"I'm releasing you by request of my sister. I trust her decision that you are true of heart, but mind you..."
She walked into the cell, and looked at you face to face.
"Do one thing to harm my little ponies, and you will regret it for the rest of your natural life." With that, she unlocked your leg, and smiled at you. You could tell it was a fake smile, but it was threatening and comforting at the same time. Kinda like that off presence... "I will show you to your sleeping quarters."
She signaled you to follow, which you were reluctant to, especially after a performance like that. You stood up and cracked all possible bones that could be cracked. You began to follow her, much to the dislike of apparently every guard in the castle. They gave you the evil eye wherever you went.
----------------------------------------------------------
Luna sat in the guest sleeping quarters closest to her own. Two doors down was where she would sleep, and in this room the strange human would sleep. She had fooled her sister into trusting the human, which she prided herself much on.
At this point in time she had no interest in overthrowing her sister.
Simply forcing her to step down willfully.
Well.
Not quite willfully.
She'd simply not give her a choice.
She turned her attention to the sack of weapons in the corner of the room, and the sword sitting next to it. She was going to assign the human the position of her personal guard. The sword weighed about as much as the bat, and she needed you be able to use it. Being immune to most magic, you were damned near the most powerful being in Equestria, even if you had no magic of your own.
She smiled a wicked smile, and began thinking about how she would explain her plan to you.
----------------------------------------------------------
You arrived at your sleeping quarters shortly, after nearly having to beat down about five guards who thought you were holding "Celestia" hostage.
What a weird name, Celesita...
Your thoughts were cut off when she loudly announced you were at your room. You thanked her and ran inside the room quickly.
You slammed the door shut and let out a breath you didn't realize you were holding. You put your head back against the door and close your eyes. An awkward walk to your room the say the least. Half the time you were sure either a guard was going to try and kill you, or if the 'princess' herself was going to eradicate you.
Thankfully, neither happened.
"Good, you're here."
Your whole head flinched, and your eyes locked onto the source of the voice.
The damned blue equine.
"You're 'Luna' I take it? Celestia seems to really trust you, but that trust seems misplaced. Why did you let me go?"
"I suspect it's time I told you my plan."
You sat down on the bed, and looked at her while she sat on the couch across from you. By the look on her face, you're going to have to topple another government.

Sorry for the short chapters, guys. I've got a busy summer and finally found a day off to write this for you. Hope you enjoyed.
