THE FOLLOWING IS AN AUDIO TRANSCRIPTION FROM SITE 291b’S INTERROGATION ROOM 7, NORTH AMERICAN BRANCH.
INTERROGATION SUBJECT: SUNSET SHIMMER, #313787 - SS
LEAD INTERROGATOR: AGENT SUSAN GREEN - SG
START OF RECORDING
SS: Hello! (Slamming of the walls and table is audible) Hello! Anybody? Let me out! It’s dark in here, let me out!
(Lights turning on is audible)
SS: W-where am I?
(Door opening is audible)
SS: Wh-who are you? And where am I? Are you police? Look, if this was about that parking ticket, I was going to pay next Friday.
SG: Have a seat, miss.
(Chairs moving audible)
SG: I said, have a seat.
(Chair moving audible)
SS: Who are you? And what is this about?
SG: Name?
SS: Excuse me?
SG: Name; for the record.
SS: Sunset. Sunset Shimmer.
SG: Occupation?
SS: College student.
SG: Species?
SS: Excuse me?
SG: Species. Nationality if you will.
SS: (A pause) Canadian?
SG: (A pause) Hmph. World of Origin?
SS: I’m sorry, but I’m not sure where you’re going with-
SG: Ms Shimmer, do not take me for an idiot. You’ve hit strike two lying to me; your third may be your last.
SS: (A pause) I want my lawyer. I don’t know what I did, but I have rights.
SG: On the contrary, Ms Shimmer, you have no rights. You are an illegal alien by every definition of the word. And if you continue to fail to cooperate, drastic measures will have to be taken.
(Sounds of tinkling are audible. Subject was noted to be reaching for her necklace trinket.)
SG: Do not bother trying to cast magic here, Ms Shimmer. We have our ways to nullify its effects in this room.
SS: (Sounding terrifed) Who are you? CIA? CSIS? FBI? MIB? Some other secret shadow organisation?
SG: Something of the like. If you want answers, it would be best if you cooperate and maybe then you’ll get your answers sooner than later.
(A pause)
SG: Let’s try this again; Species.
SS: (A pause) (Low voice) Pony. Subspecies, Unicorn.
SG: World of Origin?
SS: Equus. Country, Equestria.
SG: Purpose for being here?
SS: It’s… It’s complicated.
SG: Try me.
SS: I… I came here as a result of a tantrum. I wanted revenge on my teacher, so I came here to find a means to do so.
SG: I’ll put that as hostile intent.
SS: No, it isn’t like that!
SG: Isn’t it? You travelled here to plot your revenge. You brought with you a magical artefact from your world to abduct and enslave a portion of the population to act as an army to invade your world. Doesn’t that sound like hostile intent?
SS: I didn’t mean to… I mean… I didn’t want to… That was the past. I’m different now. I’m trying to make amends-
SG: What you are now does not matter in this inquiry. What you were and your intent was is the focus of this inquiry.
SS: Why?! Why does that matter to you?! And again, who are you people?!
SG: Well, to answer that question, Ms Shimmer, if the world is at stake due to the reckless actions of an individual who clearly doesn't know any better, it matters to us. As to who we are? We are the Secret Global Intelligence. We are the people who ensure that this world isn’t torn apart by outsiders, the supernatural and beyond. So when you ask if your actions in the past that resulted in numerous potential world ending events matters; to us, it gravely does. No matter how you feel about it now.
SS: … How much do you know?
SG: Oh, more than enough to sanction your termination. But that’s not why we’re here.
SS: Then why are we here? Why am I here?
SG: You’re here because you are a threat. You’re here because five years ago, you set in motion events that are slowly ending our world as we speak.
SS: What?
(Papers within a folder unshuffled is audible)
SG: (Slamming a set of papers in front of the subject) Five years ago, you brought into this world an artefact that is magical in nature and used it to mind control more than three hundred students and staff in an attempt to invade your world of origin; all while morphing into a class 3 demon.
SS: Th-that was the past! I’m no longer like that. I’ve changed! I know I’ve screwed up before but-
SG: You are not paying attention, Ms Shimmer. We don’t care if you’ve changed. In fact, we don’t care if you won’t or can’t repeat what you’ve done before your reformation. What we care about is what you’ve set in motion.
SS: W-what do you mean?
SG: Question: What happens when you introduce a new rule of reality into another world with their own fixed set of rules?
SS: I… Well… I mean, magic exists in this world, even before I came here. Your myths, your lores, your legends; a lot of them told in similar ways across the world is proof that such concepts exist. The geodes I’m wearing is proof enough of a form of magic beyond Equestria. There couldn’t have been any harm with bringing the Element of Magic here.
SG: (Sigh) Ms Shimmer, did you even consider the Rules of Compensation?!
SS: The what? Rules? Compensation for what?
SG: Wait, do you mean to tell me you travelled into this world without considering the consequences?
(A pause)
SG: Oh my God. (Slams the table) You came here without knowing the rules?!
SS: I… I… I was mad back then, alright?! Celestia denied me of becoming an alicorn so I ran here to prove I could achieve beyond what she couldn’t! I see now it was stupid of me, but- What?
SG: Oh believe me, you have no idea how far your stupidity has done to damage our world.
SS: W-what do you mean?
SG: First thing to know of inter-dimensional travel are the Rules of Compensation: What is lost cannot be regained, only compensated. When one is added, something must be lost to compensate. When you add an ice block into a full glass of water, excess water spills out to compensate for the mass. When you lose a cog from a machine, it must be replaced to keep the machine functioning. (Yelling) When you brought your magic from your world into ours, what the Hell do you think was going to happen?!
SS: Y-you mean… All that magic that appeared after Twilight left. The Sirens, The Everfree, our surges of magic. They were a direct cause of what I did?
SG: It wasn’t just magic, you know. Have you ever wondered why you’ve never met your counterpart for the last seven years?
SS: I… I’ve never really thought of that.
(A file thrown onto the table is audible. The file contained information about this world’s Sunset Shimmer.)
SG: We did some digging. It seemed after you stayed here for two years and you weren’t planning to leave this world, our reality had to correct the anomaly that was you and remove our Sunset Shimmer, as compensation.
SS: (Subject was reviewing the file) (Gasping) Oh sweet Celestia. A car accident?
SG: Read further, there’s more to it. The accident killed her whole family and two others. We found out they were on their way to a hospital after discovering a tumour growing in her for two years. Just about the same time you entered our world. And no, medical reports state that her family never had a history of cancer nor was her lifestyle the cause of such development. It just showed up one day out of the blue.
(Heavy breathing from the subject was audible)
SS: (Hyperventilating) I did this?! But that’s impossible! If that’s the case, how come nothing happened to Twilight in this world or Equestria’s?!
SG: Simple, she didn’t become a permanent resident in this side of reality. You on the other hand trapped yourself here for two years before your next chance to return. And you did for a brief time, only to bring back with you a magical artefact. That was the very night the accident happened by the way. That drive to the hospital for her surgery could have saved her. But when it became clear that you intended to stay, compensation had to take effect. We have no control over this. You did.
(Sobbing became audible)
SG: But her case is of little relevance in comparison to the magical artefact you brought here and activated.
SS: (Sobbing) There’s more?
SG: Of course there is. When you activated what you called The Element of Magic, you ignited a shift in our world. By activating a powerful artefact that is a centrepiece of another world, you added a new rule to our world's laws of reality. And in doing so, our world’s laws are slowly being overwritten. It starts small, like it usually does. It starts in one area of the world and slowly spreads like a plague as more people gain access to it. Little things like spontaneously growing wings in the middle of a concert to large things like artificial storms. Normally, our organisation could contain such an outbreak, but the more it is used the more it spreads, and we could not be everywhere at once.
You’ve been here long enough to know that our world is not as harmonious as your old world. How do you think the world as it is now will take the existence of magic of your scale? Machine guns, tanks, jets, battleships, even nukes will become obsolete. Third world countries and more unscrupulous ones will no doubt take advantage of these new changes to our world. Then every nation across the globe will be in an arms race, followed by civil wars and a third world war. And from there it could only get worse.
(Crying stopped)
SG: The more everyone continues to use magic, the more rules of our world will be overwritten by your magic. Eventually, our solar system will cease to function the way that it should due to magic; tossing every planet, moon, asteroid, comet, and more out of orbit. We don’t have anyone like Celestia to hold the planet, let alone the Sun into orbit. Best case scenario is that we’ll be tossed out of orbit into the cold space outside of our solar system. Worst case, we’ll collide into the other planets, moons, or even the sun itself.
SS: (Sounding horrified in a low voice) H-how long?
SG: We’ve been trying to contain the magic ever since it caught our attention during what you called the Friendship Games four years ago. Since then it spread too far for us to contain effectively. If it continues to spread like it does now, we estimate within this decade the entire North American continent will be contaminated with Equestrian Magic. The whole world within the next decade. An economic collapse caused by the magical arms race will follow within the second decade, followed by civil wars across the planet. The third decade, all nuclear weapons will be fired and/or tossed like garbage after being proved to be obsolete. Within that decade, World War Three with an estimate of one-third of the planet’s population wiped out. Fifty years from now, the moon will stop spinning around us. And in less than a century, about eighty years from now, the planet will lose orbit from the sun, followed by the rest of the solar system. By then, we would have wiped each other out from the wars.
SS: (Crying uncontrollably) What have I done?! Oh dear God, what have I done?! I doomed us all! I doomed us all! Applejack. Rarity. Rainbow Dash. Fluttershy. Pinkie Pie. Twilight. … Hic. I’m sorry! I’m sorry! I am so sorry! Hic. … I killed you all!
(Screaming cries are audible for five minutes before dying down)
(Water poured into a cup is audible)
SG: (Sigh) As much as I would like to offer you my sympathies, our organisation doesn’t have the luxury to waste anymore time.
SS: (Sniffling) What time? You said so yourself, you can’t contain the spread. (Sobbing) Oh Celestia, I killed my friends, I caused my counterpart’s death, I doomed this planet. Just kill me already.
SG: Oh believe me, I want to. However, that's not my call.
(A gun and badge slammed onto the table is audible)
SG: As for you dooming the world, I did say we have a hard time trying to contain it. You on the other hand seem to have a knack of finding them.
(Sobbing stops)
SG: You have two choices Ms Shimmer. Option one: We terminate all known elements of Equestrian magic from this world, which includes you, your friends, your schools, this entire region of the continent in an effort to contain the spread. Option two:
(The badge and gun shoved towards the subject is audible)
SG: You and your friends will join the organisation. Your knowledge, experience and knack of bumping into these things will help us contain and eliminate Equestrian magic from the planet completely. You will disclose all information you have to help us find what we’re looking for and you will be trained as field agents to respond in containing any and all traces of Equestrian magic. The choice is yours.
(A pause)
SS: I… I’ll do it. If it means making up for what I did, I’ll do it. Although, I can’t say for the rest of my friends. They’ll need to know the situation.
SG: Oh trust me, they know. We’ve interrogated each of them already. They all agreed so long as you do. In fact, they’re right behind this glass mirror watching.
(A thud behind the mirror was audible)
Pinkie Pie: (Muffled voice) Hi Sunset!
SS: (Snorts) I guess I don’t have much of a choice then. I’m in.
SG: Good. We’re done here then.
(Chairs moving are audible)
SS: By the way, I didn’t get your name.
SG: I’m Agent Susan Green. Welcome to the SGI.

Author's Note
Happy Spooktober folks! 
For those of you curious, yes this story's explanation of the Rules of Compensation is the same on for my Words of Advice from the Many Worlds of Twilight fic. This fic is more of a test run on how the rules work (and if it sounds right).
Let me know what you guys think in the comments below. More chapters from my other stories are on the way.
