"He needs to go back"

"What do you mean? He's already dead, I claimed him and cleansed him, he stays with me"

"Did you even check his flank when you were doing that barbaric bathing ritual of yours? Or were you too caught up in the moment you stupid little bitch"

"SHUT UP! He's MINE you ASSHOLE!"

"We'll see about that, He has a destiny to fulfill, and I'm going to see it through"

"No! Stay ba-*SNAP*AGH! My wings!"

"Next it'll be your horn, now let me through"

"F-fine, but he'll be a complete mess in the living world, the cleansing does take a toll"

Sombra had the sudden sensation that he was being lifted from his bed. He attemped to struggle against it but he was so tired. . . All he wanted to do was sleep and forget the pain. He hit the ground with a thump.

He could only see an outline of the figure that had taken him from his bed and eternal sleep. It had a large pair of wings and a horn.

"Wha-What do you want?"

"You to make a choice"

"Why?"

"You have drive, I like that in ponies, I need you to finish your job"

"But that's impossible. . .I already have my cutie mark, my destiny"

"I have bigger plans for you. . .Do you think you just died because you screwed up?"

"Uh"

"Everything happens because I plan it or a plan exists for it, Somber Heart. The rise and fall of empires, of countries, of individual ponies. Don't you understand? It's futile to say no, because you're going to say yes. As I predicted my younger sister banishing me from MY realm of existence. I had no plan for that, thus my influence is limited to mortal beings who delve into dark magic. I'm giving you another shot at life, as yourself, rather than rot in here for eternity"

Sombra was dumbfounded, here was an alicorn claiming to control fate itself. He wanted to say no to the bastard and set the record straight, that Somber Heart was not a cosmic plaything, but at the same time he wanted to see if this 'master of fate' could bring him back to life.

"All you need to do is say 'yes' and I shall whisk you away into a new body to fulfill your destiny."

Sombra decided that it was now or never.

"Yes"

It was 4 o'clock in the morning in Ponyville. Nopony was awake at this godawful hour of the morning. But if they were awake the would have seen a stark white silhouette set down a unicorn with a black mane and a grey coat of fur, the most unusual feature of him was his slightly curved horn. His cutie mark was a set of four black gems pointing in four different directions. He lay asleep in the market square.

Market was to start in four hours.
