When I awoke, my mind was ablaze with the intense hatred that had been born within a dream. The mare at the door said nothing of my new demeanor, nor of the fact that instead of opening it, I simply burned the door to cinders. I did the same with those to the training hall. Sombra awaited me there, but before he said anything about what to do to the targets, I broke shards of crystal from the walls, and blew them into the targets hard enough to embed them into the crystal walls behind them.
Sombra raised a brow, as if his interest had been peaked. I didn't even have to look at the attack dummies in order to destroy them- a simple thought and they all turned to ash and smoke, except for one. That one was levitated into the air, and thrown against the target with the long crystal jutting out, which effectively gored the doll through the back and out the stomach.
"Hm," said my king. "Tell me, boy. Why is it you have improved so significantly overnight?"
"Many reasons, my lord." I said evasively. "But the chief among them being loyalty to you."
King Sombra was obviously pleased with such an answer. Unbidden, I followed him out of the training hall. He lead me to a seemingly featureless wall, which, at his touch, dissolved into shadows. I followed him inside the room that was revealed, where he stood before me with a strange black amulet, set with a small red gemstone.
"This is the Alicorn Amulet." He explained, levitating it over to me. "It grants the one wearing it much power, and cannot be removable by anyone other than the bearer."
"My king, why would you not use such a treasure to supplement your own power?" I inquired.
"It is impossible for one such as I to do so, I'm afraid. For you see, boy, while I may appear to have a corporeal body," Sombra lifted a crystal to his neck, and it passed right through as if he were made of mist. "I lack the capability to wear such an object. I require crystals to create a new body, and a large quantity is hidden beneath in Canterlot's Crystal Labyrinth. That is why I required you. I needed you to wield the power so as to storm Canterlot-"
"And eliminate the Princesses, leave the throne vacant, and give you an opportunity to craft a new body from the labyrinth." I finished. "A chance for vengeance for me, a kingdom for you-"
"And a wonderful panic for me!" Discord said, clasping his paw and claw around my stomach in a hug.
My first natural instinct was to headbutt my assailant. My second was to question where they'd come from, but since it was Discord, that could be anywhere. Still, I was pleased to hit the god, even if it did earn me a glare from my king.
Obviously the two were working toward a common goal. I could see how both benefited from the one-pony siege, though I was not happy that Discord was. But, if Sombra was working with him, I supposed I could as well, for some time. After giving a fake, reluctant apology to the draconequues, I turned back to my king.
"So, to be clear- I am given an opportunity to destroy anyone who gets in my way, and kill Celestia and her sister?"
"You are correct." Sombra said, clasping the amulet around my neck. So much energy. So much potential. And all of my rage to direct it with.
The mare walked in, with a kind of black cloak in her mouth. She threw it over my head, the hood hiding my face. It was probably for the best that no one who knew me saw me was I entered Canterlot. With my coat greyed (for reasons unknown to me) and my eyes now like hers, green and purple, it may arouse suspicion.
Perhaps after removing the double monarchy, I could deal with Discord. After that? There's no doubt I'd be appointed some position of importance. I could have, I could do whatever I wanted. No one could stop me.
