I am King Sombra, the true ruler of Equestria! I am the bringer of darkness and ruler of shadows. All shall bow before me!The land of Equestria looks pretty and nice on the outside, but I always knew the truth. Even as a colt, I knew that the world is a cruel and brutal place. Only the strong survive. And I am stronger than all! I deserve to rule this world!
I first rose to power when I created the Alicorn Amulet. I used it to strengthen my magic so that it would become tantamount to an alicorn's. Not that I wasn't the greatest sorcerer that ever lived, of course. I am King Sombra! Nopony can stand against my might!
With the amount of power I had at my disposal, I could have easily stopped wars or created cures for terrible diseases. But I was never interested in any of that. A king needs a kingdom to rule over. Or in my case, an empire. I enslaved those pathetic Crystal Ponies with ease, and immediately set about trying to expand my rule. That was when those two upstart alicorns interfered. By some cheap, dirty trick, they banished me from my own empire and encased me within the ice of the frozen north, stealing my amulet from me in the process. I had the last laugh, though. I made it so that the empire would vanish with me, and bring me back with it when it returned.
When I come back, and I will come back, I'll make those puny princesses pay for what they did. It shouldn't be too hard. Before too long, I'll have complete control over the minds of every inhabitant of this world. Every stallion, mare, colt, and filly will be my slave. Then they'll do whatever I want them to do. If I tell a pony to kill his children, he'll do it. That should be fun to watch. I also like the idea of making them all fight a war with each other...
Some ponies may resist. Let them try! I will crush them all. I will take their families from them. They will try to beg for mercy while choking on their own blood. They will learn too late that my victory is inevitable.
My subjects will die of old age eventually, like all pitiful mortals do. Because they won't feel love anymore, there will be no more babies. So I'll just have to force them to make some. Then I'll have an endless supply of slaves to torture, more lives to make a living Tartarus.
This is all in the future but the future is always coming. Just as day turns to night, shadow will rise and extinguish all light. At the end of time there will be only darkness, and I will rule that darkness. It lasts eternally and so will I. I will become a god! There will be no end to the beautiful suffering! I am King Sombra! Fear my name!
