Fires of hell- Pre Purity's Disruption!
A lawless place, uninhabitable for ponies, home to some of the worst imprisoned threats, and an Alicorn, who was at peace, woke up after walking for half a lifetime.
This is Prince Firestorm, a 4500 year-old Alicorn, who has a deep red coat, jet black mane, with a red strike going through both his mane and his tail, with a supernova for a cutie mark, he was the most powerful Alicorn in living memory, and he knew it. That was what landed him in this terrible place, so why was he here if he was at peace?
Using his magic, he had made a doppelgänger, who represented his anger, and fury, an exact opposite to him, his name? Lord Diablo. This Alicorn was powerful, and had an awful temper, and he tended to hang around Firestorm, just to annoy him.
Diablo lit his horn black, and started a thunderstorm. Lightning began crashing down around them.
"What's the point diablo?"
"Because it's fun! And I can annoy you at the same time!"
"Oh why don't you piss off!" Firestorm yelled, and he bucked Diablo, sending him flying a few hundred yards forward, and he disappeared, and appeared behind him and they both crashed to the ground.
"Gods sake diablo, you could control this place! Why are you still clinging on to me?!"
"You know what? Your right! I'm stronger than you! I can have this place. Give it a new regime!" and he disappeared in a blast of black lightning
"Great, what have I done..." he sighed, and then continued walking.
A few weeks later...
Firestorm was resting in a burnt tree, when he saw diablo flying overhead, followed by an abundance of residents of the slip, he sighed and leapt off the tree and started walking. Then diablo appeared in front of him.
"Oh hello copy"
"It's Diablo, is walking the only thing you've achieved?!"
"I've been here for 2500 years, you've been here for 250, and since this place is endless, a walk was what I wanted to do, it's calming"
"You sir, are a fag" Diablo laughed.
"Piss off" Firestorm said, he then rejoined the front of the slip residents in the sky. Then, a portal appeared in front of him, and Celestia appeared on the other side.
"Your time has come Firestorm, your sentence is served"
"Thank you Celestia, I'm coming through" he said, as the portal widened. Diablo then saw it, and swooped in and shot through, and it quickly shut.
"Shit!" he said, and then desperately attempted to re-open it. Sparking his horn, quick bursts came out of it, and then stabilized into a strong light, and a line of light appeared where the portal was.
"COME ON!" He yelled, as the light began to creep across his body, and he was soon enveloped in a bright red light, he was unlocking his true potential. As he prised the portal open, and released the power, and flew straight through, back home.
He arrived in the throne room, and he saw Celestia bound by arcane chains, and diablo was tearing canterlot apart. (I'll be back Celestia) he thought, as he leapt out of the window, and flew towards six ponies that were running from canterlot, he cracked a sonic boom, and slammed down in front of them.
"Turn around"
AN: Sorry this one is short, I had the idea, and then I couldn't continue it, so here you go :)
