My Little Pony - The Legend of Friendship (MLP remake with male OC added)

Season 5 Intro - Free again

Canterlot...

Ponies were unconscious on the ground, the Royal Guard was defeated and even Princess Celestia, Princess Luna, and Princess Cadance were all banished to Tartarus. This was all done by Tirek, an evil creature who wanted to steal all the magic from Equestria. He was at first weak but with the help of Discord, the Lord of Chaos, who was supposedly reformed and intended to deal with him before he grew too strong, he managed to steal the magic from almost every pony in Equestria. This allowed him to grow far stronger than anyone else and made him almost invincible.

Princess Celestia however, knew what to do. She knew that Tirek was after the magic of the three Alicorn Princesses and came up with a plan. The three Princesses had to give up their magic so that Tirek would no longer be able to steal it. They entrusted their magic to Princess Twilight Sparkle to keep it safe. She was the element of Magic so she would be the only one who could control all of this magic and maybe even stand a chance against Tirek if she learned how to use it.

Tirek was not aware of the existence of another princess but Discord recently informed him about it. Only moments before, the two went to Ponyville, Twilight's home, to go after her Alicorn Magic, ready to take it away from her. They left Canterlot in this sad state. There was nopony who could even attempt to stop Tirek and Discord. There was almost nopony left to even stand.

Almost nopony...

Inside of the Canterlot Dungeons, one pony was completely unaware of everything that happened. He was locked away, cut off from the outside world, left into a prison cell so that he could no longer harm Equestria in any way.

"Hey!" Could be heard echoing through the empty hallways of the dungeon. "Is anyone there!?" The pony shouted through the hallway again.

Normally, ponies from the Royal Guard were constantly patroling around the hallways, even if there was only one pony locked away at this moment. But no one was there anymore, which was the reason why this one pony got more and more aggressive and annoyed.

That one pony was holding his cell bars and tried to look around the hallway to see if there was anypony who could talk to him. "Hello~!?" He shouted once more only to get his own echo back, followed by silence again. "Argh, forget it!" He then said before he gave up to waste his energy.

The pony inside the cell was a Unicorn stallion with a dark-purple colored coat, a dark blue W-shaped mane, with yellow stripes on it, dark blue eyes, and a dark blue mist cloud as a Cutie Mark. He also had a device on his head that prevented him from using his magic. It was the former leader of the Storm Wings and a member of the Outcasts: Mystic.

After the plan of Fade, another member of the Outcasts, failed, he was imprisoned because unlike the rest of the members, he did not regret any of the things he did. His hate for Princess Celestia made him dangerous, and when it comes to magic, he was pretty strong as well. If would have set free, then Equestria would be a much more dangerous place.

The Unicorn was walking around his small cell until he got tired and just laid down on his bed, looking out of the small window that was a few meters above him.

"It's been a while since I saw a Royal Guard wandering around here," he said in a bothered tone. "Usually, I can hear them out there from this window but it's so quiet. First, one after another left those hallways, then everything outside became quiet, and now there is nothing. I usually have some of them checking up on me at this time of day. What is going on!? Did those Changelings attack again!? No. I would be able to hear all those Changeling if they attacked this place, right?"

It was confusing Mystic but at the same time, he didn't care too much what happened. If there was anything that was out there attacking Canterlot, then it was not his problem. If Princess Celestia would suffer from this, then even better. The stallion decided to close his eyes and take a nap, nothing else he could do anyway.
