Somewhere, beyond the realm and existence of Ponyville, where no physical life could ever even hope to exist, there was a force of darkness, floating through the realm. The darkness manifested itself into a shadow; a shadow of pure fear and terror. In the darkness, two large green eyes opened and there was a loud snarl. Then, the sound of menacing laughter could be heard as the voice in the darkness began to speak.
"I see........ you have finally arrived.... (Chuckle)..... good, very good. Yes, it is I, Sombra..... King Sombra.... I'm sure you have questions. I will not answer any... after all, why should I? But I suppose I could answer just one little question....... How am I alive? Well, it's quite simple really........ Yes, I may have been defeated at the Crystal Empire.... shattered like a glass bottle..... however, I never died.... You see, if you're going to kill a unicorn as powerful as me, you better do it right..... While I may have been physically killed, I was able to live on spiritually because of one simple thing....... my horn."
"Because my horn was never destroyed, I was able to keep my magic alive, thus keeping me alive..... I became one with Equestria, I merged with the atmosphere, I I became a part of life itself...... I've longed for my return for so long now...... during that time that I have been trapped, I have watched over a certain pony..... a pony who has grown with power since my defeat...... a pony who has been through many things...... a pony who has faced the many dangers of life...... a pony who is worthy to die by my hooves...... Yes...... Twilight Sparkle..... or should I say, Princess Twilight Sparkle....... (Evil Chuckle)....."
"You've grown so much since my defeat, Princess....... My have you been through a lot..... Defeating Tirek, befriending Starlight Glimmer, defeating Queen Chrysalis, taking out the Pony of Shadows, reforming Tempest Shadow, defeating the Storm King, and recently imprisoning Cozy Glow...... not to mention you are a unicorn no longer..... now, you are an alicorn.... Yes, you've had quite a fascinating life..... I wonder, what is it that keeps you going? What is it that gives you the power to fight off against the evil of Equestria..... You've caught my interest, Sparkle...... in fact, you've earned my respect...... anypony that earns my respect is something special indeed..... all the more of a reason to kill you....."
"(Evil Chuckle) I know what you're thinking Sparkle...... how could I possibly kill you? After all, now that you're an alicorn, you have been granted the gift of immortality..... quite troublesome if you ask me...... However..... there is still a way that I can kill you..... Alicorns can indeed be killed, quite easily as a matter of fact..... it just requires the right item...... a simple stone...... a stone that can resist magic..... a stone that can pierce through magic...... a stone that is quite common, yet rare...... Luckily, I know where to find such a stone....... unfortunately....... the source of the stones was destroyed a while back, but I watched the pieces get scattered..... I know where one of those pieces is..... all I need is one single speck of that stone, and your life is damned......"
"Now I know what you're wondering..... why am I after Twilight Sparkle and not Spike or Princess Cadance or anypony else? It is quite simple..... Yes, Spike may have been the one to bring the Crystal Heart to Cadance...... Princess Cadance may have been the one to use its power to defeat me...... but who was it that led the charge against me? That's right....... Twilight Sparkle..... it was her that led the charge..... it was her whose leadership resulted in my defeat.... it was her who damned my soul...... therefore, all credit goes to her..... I long to get my revenge on you, Princess Sparkle.... You were the one who killed me..... You were the one who took away my victory..... You were the one who stole everything from me..... and you will be the one to die at my hooves......"
"You really thought it was over just because I was dead? Did you really feel like it was safe just because of my defeat? Did you really think you would stop me just like all the others? Do you really think I'm just like the other 'villains' that have crossed your path? I was never given the time to bring my power down onto Equestria..... I was never given the chance.... I was never given the opportunity to enact my revenge..... All because of you..... Twilight Sparkle......"
"You are such an incredible pony, Princess..... A pony with so much potential..... A pony with such a bright future.... I will be the one to take everything from you.... just like you took everything from me..... I will crush you..... I will shatter you like glass..... I will overthrow your kingdom..... I will obliterate your school..... I will kill everypony you have ever loved..... I will be the one to finally kill the Princess of Friendship..... your legend will die at my hooves...... You and I, we are destined to be..... We are destined to die by each other's hooves..... You..... Are...... MINE....."
"I long to finally meet you properly Princess.... our battle will be legendary.... it will last for ages..... It will be our greatest moments in life..... I will rip out your heart..... I will crush your body to nothing..... I will break you..... You will fall dead at my hooves..... You will die..... Your reign..... is coming to a close..... Twilight Sparkle....."
"However, I cannot enact my revenge while I am trapped here..... but I don't need to worry about that..... there are two ponies coming to set me free.... one of them I will leave to endlessly wander and roam all of Equestria in her endless search to find me..... the other..... I will guide her to me.... She will set me free.... I feel like you have earned a second chance...... a second chance to get your revenge..... together...... I am sure we can finally be rid of those ponies..... Equestria.... Will...... Be..... Mine....."
"Come..... free me.... Chrysalis..... free me..... free me..... free me...... free me..... free me....."
King Sombra's words echoed throughout the vast empty void he was in. If you were with Sombra at that moment, your whole body would have shook due to the power in Sombra's voice. Despite being trapped in this strange realm, Sombra's voice was able to travel through to the outside world of Equestria. Now, it was only a matter of time. Sombra grinned as he waited to be set free. Soon, Equestria would be his.
