Meanwhile in the Changeling kingdom...
Chrysalis was minding her own business when a group of battered and bloodied Griffins and Changelings stumbled through the door of her throne room.
"My queen, The human has escaped! We've looked for it everywhere, but we could not find it!"
"What do you mean by 'Human' drone?" Asked Chrysalis.
"Well..."
about half an hour of explaining later...
" So what you're telling me is that in trying to defeat Equestria, You summoned an extremely powerful and angry being here, gave him the power to destroy us all, and then let him get away!!!?"
"Ye-yes your highness"
"And which one of you thought this was a good idea?"
One of the griffons decided to finally open their mouths and say something.
Well, It was none of us, The decision way made by the most powerful mages from our own respective nations. Who are currently in the process of being buried.
"I see, is there any way to stop it?"
"Unfortunately, that knowledge was lost when it killed our mages, it was last seen heading towards the equestrian border."
"It, could be trying to ally with them, We must stop it immediately!, Griffon ,go to your emperor and tell him to mobilize his army. We march on Equestria at once, and- Wait, Where are the Dragons?"
Well...They are currently out searching for the Human, We will have to wait until they return."
"Unacceptable!, send one of your griffons to kindly ask their lord to join us."
"Understood, your majesty."
Meanwhile in Ponyville...
The main six led William to twilights library, and As he walked He began to realize something.
"Uh, interesting question, but why are all the buildings here painted pink?"
This resulted In only a shrug from Twilight. Who seemed all but disinterested in his criticism.
"Holy ####," William changed the topic. "I can't believe I'm actually here, and of all the people in the world, I have to be the one to make first contact." He thought to himself, chuckling just out of earshot.
Twilight looked around the room, and then back at William.
"I don't think any of these chairs could support your weight."
"No worries, I'll just stand." Almost as soon as he had said that he felt an aching pain course through his legs. Causing him to wince.
"AGGGGH..."
"Are you alright darling?" Asked Rarity, setting a hoof forward and squinting at him.
As soon as William hear that his face darkened, "Never call me 'darling' again. Understood?"
"And why is that?"
"That is a long story, one that I neither have the time nor want to share with you."
"And I think I'll just sit on the floor. You would be surprised what several days of nonstop physical activity can do to a person."
Twilight got out her notebook. "Alright, First question, what are you?"
"I am a human and I am currently 16 years of age."
"I've never heard nor read about your species anywhere, you are already almost as tall as Princess Luna, and you're only sixteen years old?!"
"Yup."
"Fascinating."
"Alright, second question, Where did you come from?"
"This is going to take a lot of explaining."
"I live one the outskirts of the city of Sacramento, The the state of California, Which itself is located in the United states of America.
Where Is that?, I've studied maps of the world since I was a foal, and I haven't seen or heard of anywhere titled that."
"And what do you mean by state?"
"Get comfortable, We are going to be here awhile. It all started about 300 years ago in my home dimension."
"Wait! what do you mean by home dimension?"
"SHHH! I'll tell you when I'm done with this."
About an hour and a half of American history later...
"And That's how my home nation became the dominant power on our planet. And also, in my opinion, the coolest power on our planet."
At this point Fluttershy was hiding In the back corner of the room, quivering. While the rest of them were lining up front, looking like they were about to fall off their seats."
"Your country, It's so...violet, How can you live like that?"
"The fact of the matter is, Twilight, and the rest of you. That our country is pretty much as good as it gets in our world, don't even get me started on the middle east, or north Korea. You see, Our country was born out of Tyranny and oppression, and it's founders took it upon themselves to make sure that would never happen again."
"I understand, my last question, Where did you come from?, a while ago you said, 'Home dimension' What do you mean by that, and don't think I didn't notice that armor of yours, or that weapon you have in your paws."
"Hands, Not paws, I take great offence to that."
"He sighed, I was trying to keep it a secret, But Here it is I suppose. It started out like any Friday evening would in my world..."
Another 20 minutes later...
"And then I met a unicorn by the name of Greystone..."
10 more minutes later...
"And so here I am now."
He noticed immediately that his story had done nothing to calm the six's mood towards him.
"Y-You killed all of them?" Questioned Fluttershy. "Well, Yes, and I did it for what I consider the greater good, and now that I'm here, You best not waste me, and I would really like it if you could figure out how to send me home."
"Oh, and Fluttershy, Can you please stop freaking out over Everything?, its not like the whole world's out to get you...at least not all the time."
"I'll See what I can do", Responded Twilight, "As for now, make yourself at home here, just don't break anything."
"And as long as you don't hurt anypony." Said applejack
"So long as they don't hurt me first, but then again ,why would they?"
"Thank you all." He peaked through the doorway and noticed that they had managed to calm the townsfolk back down.
"At Least I'm safe for now, Although, I have a feeling that it won't for very long."
He left the library and stepped out into the town square.
"Look on the bight side, at least I'm surrounded by adorable talking horses."
"At the unfortunate cost of me having to put of with all these stupid colors everywhere."
He put his hand on his forehead and groaned.
"I'm starting to think this was at least in part, a bad idea." Angered, he stomped off, murmuring obscenities to himself.
