After they gave me a rather awkward introduction into the concept of a 'sheath', we all seated ourselves in a comfortably furnished room in the crystal castle, to contemplate what we would do next. After all, the giant protector of all of Equestria had now shrunk down to the size of a normal Dragon.

"Okay, maybe this isn't as bad as it looks. Maybe we can find a way to revert this?" Twilight said while walking in circles in the middle of the room.

"Twi, calm down, yer twilightin' again." Applejack commented.

"I know, Applejack, I know. It's just that I don't even know what happened and walking in circles helps me think."

"Yeah, I don't know... To me, it just seems like you're running in circles." Rainbow joked.

"Oh, har har. Now's not the time for bad jokes, you know?" Twilight said, annoyed.

"Hey, I can make jokes whenever I want to! Besides, it seemed like we needed to lighten the mood in here a little."

Rainbow and Twilight went on arguing about the time and place to make jokes. Well, actually it was mainly just Twilight lecturing Rainbow, but that's only a fact on the side. I quickly tuned them out anyways and went to have my own little chat with a certain deity, who would certainly know a thing or two that I needed to have explained.

Yo, Navi, you there?

"Yes."

Whoa, hey man, where have you been? I thought you left me when I couldn't reach you back there!

"I went to get a cup of coffee. Really needed it."

Ah... well, whatever. Yo, Navi, I have a little problem here, can you please help me?

"What problem? Do you mean your size?"

Yep.

"Uh... Yeah... you know, that's... kinda my fault."

What? How so?

"Do you remember when I brought you into this world and gave you that Dragon body?"

Well, yes, why?

"Well, euh, I kiiiiiinda was a lazy fuck when I did that."

... Come again?

"Do you want the full explaination?"

If you don't mind?

"Ok, here goes: So, first off, normally every entity in every universe has ONE form and one only. Everything and -one which/who can change their appearance are doing just that, changing their appearance. Think of it as changing your skin in a computergame. Anyways, that applies to everything. Every rock, every tree, every living being, they all have ONE form. They all have. All, except you."

Wait, what?

"Yeah, you see, you also only had one when I brought you here. However, I didn't change it into a Dragon form like you might believe, but I actually just had this empty Elemental Dragon lying around. I gave it some sick stats, made it albino and slapped it into your list of main forms. When it came to your old form, I was about to remove it, but I thought 'Nah, he can't change his forms anyways and maybe this'll come in handy sometime'. Welp, fast forward to now and your contact with the mirror. You see: normally this mirror just does what the changelings do and changes your outward appearance to that of a human. However, you already had a human form, so the universe just used that, slapped whatever of your abilites it could translate into it and voilá. That's why you looked like your old self over there."

Ah. Certainly explains some things.

"Yeah. However, there were a few more things going on. You see: every universe keeps a checksum of every entity, which, like the name implies, is the sum of all of its abilities and attributes. When you went into the mirror universe and your abilites were transferred into your old body, everything except your size was transferred. That's because the size can only ever be changed within a certain range and yours was far beyond that limit. However, it was okay since, like I said, every universe keeps its own checksum, so it translated what it could, created a new cheksum and everything was fine... Until you went back. You see: when you went back, it didn't change your form again, but did the standard procedure of making the texture change. You were listed as an albino elemental dragon? You became an albino elemental dragon. Good, now to the cheksu- ERROR. Yep, your cheksums didn't match, which normally wouldn't have been a problem, since it could easily be corrected by adjusting the corrupt value. However, like I said before, size can only ever be changed within a certain limit and since you were beyond said change limit, the universe did the next most logical thing and dumped your excess points into your lowest stat... Your virility."

Wow... To be honest, this all sounds strangely like computer problems to me.

"You probably can't even imagine how close that is to the truth. Also, did you know that you didn't make that trip just once?"

... Ok, now you're just pulling my leg.

"No, I'm serious. You made that trip like fifty times or so. The problem is that some of your stuff was already improperly translated when you first came here. Then, when you made your second dimensional travel and you had to be translated again, everything just went apeshit. What followed was a long chain of trial and error for me to seek out what went wrong in your essence and correct it. To top it all off, you actually died a few times when that rapper guy slapped you, because your abilities had been wrongly translated. Then, when everything was finally fixed and I saw you NOT die from that punch, I just told myself 'alright, time for a break' and got myself a BIG share of coffee."

Whoa... ehm, sorry...

"Ah, don't be. Not your fault, after all. Oh and also: since you now have both of your forms activated anyways, I made it so you can change between them. Just think of how you want to be big again or whatever and it will automatically be set as a trigger."

Oh really? Thanks man.

"You're welcome. Also, you should probably stop zoning out. I think Twilight's trying to get your attention."

I stopped zoning out and saw Twilight waving a hoof in front of my face. I smiled sheepishly and said: "eh, sorry, zoned out for a moment."

"Yeah, I noticed." Twilight said flatly. "Anyways, what I said earlier: we could probably try to cast a growth spell on you or something, but I can't guarantee that you get back to your old size and shape."

"Ah, don't bother, I already know how to get back to my old self." I just said.

"Yeah, well, we could als- what?" Twilight spun around and looked at me quizzically.

"I said, I already know how to get back. Don't worry about it. But speaking of worry: there's one thing that bothers me: where did that rapper guy go?" I asked.

"What do you mean, 'where did he go'? where should he have gone?" Twilight asked back.

"Well, Sunset and you said that there was no more darkness around, but you also said that this whole group was tainted, including that guy. I can't remember him showing up at the concert at all, so it's unlikely that he got hit by your rainbow blast. That leaves the question, where that guy went."

everyone glanced at each other, trying to find answers in each other's gaze. Finally, when none was found, Applejack spoke up. "Ah, don'tcha worry. Ah'm pretty sure that Sunset can handle 'im."

Meanwhile, in a stereotypically dark cave, a yellow stallion was was making his way into its depths. His cutie mark were two golden capital Bs with two vertical bars going through each and he was wearing a brown beanie. His head hung low and he was muttering things to himself, while he steadily marched forward, albeit a little slowly, probably to gain more time to come up with something to say to whoever he would be meeting here.

Finally, he reached a large, circular cavern, which was dimly lit by a multitude of torches that were placed around the wall. Or at least the walls were lit. The room itself largely remained dark, especially the middle. He walked on, before he halted on the border between the flickering light and the darkness.

"So... I see you have returned." A low, growling voice suddenly pierced the silence.

The stallion jerked back a bit when he heard it and looked down even further. "Y-Yes, my master. B-But, I, uh... I don't really have good news." He said, forcing himself not to start rapping.

"I know. Have you not listened when I explained your task? You were meant to fail. Now, what can you tell me about his strength?"

The stallion slightly lifted his head. "Well, uh it looked like those sirens wre no match for him. They just were slapped down whenever they went in." He jerked back slightly, when he noticed that he accidentally let a rap slip through. However, his master seemed to be in a good mood, since his slip was met with no consequences. "They then tried to blast him with the magic of the light because I think they mistook him for a creature of the night. It didn't do much, not even a light smack and when they were done he just sent their message in full right back. I also tried to punch him myself with my fist, but all it did was hurt myself while he took it like I missed."

"Well, what did you expect? His body may have been changed, but he was still a Dragon. Him having light magic now is certainly a nuisance, but nothing that I can't handle."

The earth suddenly started to rumble ever so slightly and one could make out a few glints in the darknes, where the light from the torches momentarily reflected from the moving body of the entity. One could not see what exactly it was that was hiding in the dark, but one could easily tell that it was of formidable size.

"All in all, the outcome is within acceptable parameters. You know what to do next. Meanwhile, I will go out and have a little snack."

The stallion nodded as his master moved past him with heavy, loud steps. All one could see was that suddenly, the light from the torches on the other side was blocked out by something massive moving past. When the light got through again and the loud steps had stopped, one could hear loud flapping sounds, which the slowly faded into the background.

When he finally heard the sounds of his master's departure, Big Bang himself started to move. After all, his master had given him a task and he would be an idiot if he were to disappoint him.

A few miles away, there lay a small rock farm, inhabited by a loving couple and their two daughters. It was nighttime and everypony was already in bed. that doesn't mean, though, that everypony was also asleep.

The last harvest had been a very good one. they earned a lot of money, which they quickly and intelligently invested into more efficient means of farming. Now, as a little celebration for the success, the couple decided to have a little fun tonight. after all, two fillies were good, but a colt would truly be a blessing.

Of course, their daughters knew what was going on. They didn't have a choice after all. the walls of their house were rather thin and their mother tended to make her pleasure well known, especially when reaching her climax. A loud, high pitched moan/scream finally indicated the end of the action and the stallion slumped off his wife's back, down onto the mattress. His wife mirrored the movement, falling over so that she would face her husband.

Both were heavily panting and the matress under them was stained with the liquids that were to soon become their third foal. They scooted closer to each other and kissed each other passionately. They broke the kiss and continued to stare, both feeling the pleasure of the other and both happy with their lives.

Suddenly, the earth was a shaken by a loud rumble. the farmer got up and went to the window to look outside, but he didn't see anything. A series of similar rumbles followed, seemingly coming closer, before they finally stopped. He squinted, thinking that he saw something, but it was simply too dark. Then, finally, he saw a large shape standing directly beside their house, moving what looked like its head upwards, before smashing down into the roof.

Screams could be heard, as their daughters's room was exposed. the farmer quickly ran over, but he was too slow. All he could see when he finally reached their room, was a massive, black jaw that grabbed hold of both his daughters, before it yanked backwards, throwing them into the air.

They both screamed as they sailed upwards, before making their way back down, directly towards the waiting maw. the farmer could only look in shock, as both of his daughters were devoured by this monster. Meanwhile, it started to move again, to the other side of the house. The sound of cracking wood was heard again and the farmer knew exactly, what that meant.

"SILICA!!" he screamed the name of his wife, while running outside, trying to come up with a way to save her. However, similar to his daughters, he could only watch. His wife struggled, tried to get away with her life, while she was held firmly between two glinting rows of sharp teeth. She struggled, she screamed, she cried and begged and then... she went limp. The teeth severed her spine, cutting her clean in two, before the maw closed and both halves were lost forever.

The farmer was filled with shock and grief, which soon turned into pure, heated rage. He looked around him and saw his pitchfork leaning against the wall behind him. In a purely rage-filled decision, he picked it up and threw it vaguely to where he guessed the monster was standing.

A metallic 'cling' could be heard, followed by a few thuds where the pitchfork hit and bounced off the ground again. Then, there was silence. A light wind picked up, seemingly coming from right in front of him, which was odd since the farm was located in a nearly completely surrounded valley. When he finally realized where that wind came from, it was already too late and the last things he saw, were two glinting rows of sharp teeth, which suddenly appeared from the darkness in front of him.

Author's Note

Yes, I had to spend 1k words just to let Navi have a little rant. Why? Because why not. Also, in case it isn't obvious: no, those rock farmers were not the Pies.

And before you comment about it: I know that the quality of this one is slightly lower than that of the previous chapter, but that's just how it goes with these build-up chapters.
