Equestria Corrupted

Hey brony pals! GreatHeart_the_Brony here with my second story about GreatHeart. This one will be completely different from my first, and hopefully just as popular if not more so. In this story- what am I doing? I'm not going to spoil anything. Enjoy.

Chapter One: Hidden Power

GreatHeart walked into the library.

"Hey, Spike, is Twilight around? I need to ask her something."

Spike poked his head out of a room.

"Yeah, she's downstairs experimenting with something. She said not to be disturbed unless it was important".

GreatHeart nodded and walked down to where Twilight was working with a machine.

"What is it? I told you not to disturb me unless it was important." she turned around. "Oh, it's you GreatHeart, what is it? I'm pretty busy."

"Well earlier today I was walking through the town square with Rainbow and all of a sudden I let out a burst of magic which did a lot of damage, and I wasn't even thinking about using magic. Then when we were having lunch I somehow fired a spell which burnt a hole through the wall. I was wondering if you could help"

Twlight thought for a moment then pulled out the machine she had used to monitor Pinkie for her Pinkie Sense.

"Strap yourself in and I'll see what readings I get. I'll look for erratic magical outflow and see what we can find out."

"Okay" said GreatHeart, and he got set up. Twilight turned the machine on and looked at the readings.

"Everything seems to be normal...wait...yes, there...got it!"

"What?"

Twilight turned. "There seems to be a lot more magical power in you that there should be, so much in fact that your body can't contain it fully.

GreatHeart nodded. "That would explain the outbursts of magic. But what could have caused it?"

"I'll keep examining the readings, in the meantime you can go, but be careful."

GreatHeart walked out and looked around in the library to see if there were any books he might want to read.

Suddenly a beam of magic shot from his horn, setting one of the shelves ablaze. He watched in horror as the fire spread. He fired a spell to try and contain it, and then rushed for a bucket of water, which he poured over it- and Spike.

"Not again", GreatHeart moaned, and left.

Two days later

GreatHeart has locked himself in his house to try and stop any magic doing damage. The accidents had got worse and worse, and Twilight still couldn't figure out what was causing it.

A knock at the door startled him, and looking out he saw Rainbow Dash. He unlocked the door.

"Hi Rainbow."

"GreatHeart, come with me. Twilight got a letter from the Princess saying that she knows whats wrong with you."

Canterlot

GreatHeart stepped out of the train, and turning he saw some guards ready to escort them to the princess. Security had been increased since the issue wi Facade, but GreatHeart wondered what the guards could possibly hope to do against a power like that.

As they walked through the town, GreatHeart suddenly realised his horn was glowing.

"Get back! All of you!" he shouted, and tried to stop it, but it was too late. A beam shot out and impacted a house, which glowed gold and exploded, sending ponies flying. GreatHeart watched in horror as spells destroyed the centre of Canterlot.

When they stopped the immediate area was in ruins. GreatHeart rushed to the palace and into the throne room.

"Princess, please tell me what's wrong and how to stop it before I kill somebody accidentally."

Princess Celestia looked up.

"GreatHeart, remember when the Elements of Harmony were used on you to give you the power to defeat Facade?"

GreatHeart nodded.

"Well, I believe some magic from them resided in you, and that is what is causing this problem. There is too much magic in you for you to control."

"How do we stop it?" GreatHeart asked earnestly.

"I don't know, at least not yet. Discord says he's working on something, and Twilight is working non stop. We will find a way to contain it, but I've got some bad news."

"What?" GreatHeart said, his heart sinking.

"As I'm sure your aware, at the moment you are too dangerous to be with other ponies. There's only one place I can think of that ponies would be safe from you, and that's the prison."

GreatHeart nodded. "I don't mind staying there for a little while, but I really hope you find a solution soon."

"We will do everything in our power to fix this problem."

GreatHeart nodded once more and followed the guards down to the prison.

That night

GreatHeart lay on his cells bed, staring at the roof, which was already covered in scorch marks from spells.

Upstairs, Princess Celestia, Twilight, Princess Luna, Midnight Moon and Discord were all at work.

"Princess, how about using the Elements again?"

"No, that would just make it worse. Luna, do you have anything?"

"No, sister, I'm afraid not."

"Discord, what exactly are you 'working on'?"

"Thats for me to know and all of you to find out, but i should be done in a couple days."

The five worked for a few hours, then all but Discord and Luna went to sleep, Luna going to do her duties as Princess of the Night, and Discord still working, a small smile on his face, and his eyes flashed once.

There we go, first chapter of a new story. I can guarantee that none of you know what's coming next, but you are welcome to try. Bye for now! /)
