Heart of Darkness (King Sombra x Reader)

Siege

Sombra looks down at me, a sinister smile playing upon his face. He steps down from his throne, looming over me and casting a long shadow over my bowed form. 

"Ah, it feels good to be myself again, to have my form restored to its former glory," he says, his deep voice echoing in the cavernous space. He places a hoof under my chin, forcing me to look up at him. "Such a devoted little servant..." he murmurs, his eyes scanning over me with a glint of amusement and possessiveness. "You have done well, Autumn Rose. You have proven yourself to be a valuable ally... and a useful tool in my arsenal."

I smile up at him, but with a flash of his horn and a crackle of dark magic, I find a chain around my neck. "Hey!" I protest.

Sombra only chuckles darkly as the chain appears around my neck, a devious glint in his eye. "Oh, don't think I didn't take precautions, my dear," he says, tugging on the chain to pull me closer. "You're my little servant, remember? I can't have you wandering off just yet."

I watch as he attaches the other end of the chain to his armor, and I gulp slightly, almost wanting to cry. "Y-you can trust me, my king!"

He snorts, amused by my statement. "Trust? Hah!" he laughs, tugging on the chain again just to make me stumble. He leans down toward me, a mocking grin on his face. "Trust is for fools, and you, my little pet, are just a tool in my hand. And I always keep my tools on a tight leash."

"Ah!" I cry out slightly as he tugs on the chain. "B-but then I look just like one of your crystal slaves!" I whine.

Sombra snickers, a cold and unkind laugh escaping his lips. He yanks on the chain again, pulling me closer so I'm practically pressed against his side. He reaches down and runs an armored hoof along my chin, tilting it up so I'm forced to look at him. "That's exactly the point, my dear," he replies, his voice dripping with mockery. "You are my slave. Just like the rest of them. And just like them, you will be chained, collared, and leashed."

"But, everything I did! I did this all for you!" I keep protesting.

His expression darkens slightly at my protest. He yanks on the chain, the metal digging into my skin and making me gasp. He leans in close to my face, his eyes full of cold cruelty. "You should count yourself lucky, little one. You have done a lot for me, I'll admit. But that does not make you special, and it does not mean you are not my slave."

He grabs my chin and forces me to meet his gaze, continuing to address me. "You belong to me. Your purpose is to serve me, to do what I ask, and to obey my every command. And nothing will change that." He chuckles darkly, pulling me even closer. "You are no better than my crystal slaves, and the sooner you accept that, the easier this will be for you."

I whimper and bow subserviently. "Y-yes, my king... but I still get my special place by your side, right?"

Sombra studies me for a moment, a smirk playing at the corners of his lips. He laughs softly, clearly enjoying my submission. "That is true. You are not like the other crystal slaves. You are unique. You have potential." He reaches out and runs a rough hoof along my cheek in a gesture that could almost be affectionate. "You will enjoy a special place by my side. A place of honor and privilege not granted to the others. You will be my... favorite."

I smile with glee. "Let's go, then. Take back your empire," I urge.

Sombra chuckles and secures the chain attached to my neck to his armored body. "Oh, we shall, my little pet. We shall... and it will be glorious." He turns and strides forward confidently, pulling me along behind him by the chain.

He leads me through the labyrinthine halls around the Crystal Empire, his strides long and confident. I stumble to keep up with him, the chain around my neck pulling taut in his grip. "You should be honored, you know," hey says, glancing back at me with a smirk. "Not many ponies have the privilege of being tied to my side like this."

"Y-yes, my king," I respond quickly.

Sombra laughs at my response, clearly enjoying my obedience. "Good answer, my little pet," he replies, tugging on the chain just to make me stumble again. "You're learning quickly, which is a good thing."

He comes to a stop in front of a massive pair of double doors and turns to face me. His expression is serious, all traces of mockery gone. "Now, you must understand. You are about to witness something few in Equestria have ever seen."

I gulp as he severs the chain so he can go take over the Crystal Empire with his dark magic. Sombra shoots me one last glance, his eyes glinting with a hint of warning. "Behave yourself," he says, his voice a low rumble. "If you wander off, you will be punished. Understood?"

"U-um, I think they want to stop you," I say, pointing ahead of me to none of than the Mane 6, my old rival, Twilight Sparkle, who looks extremely shocked to see me standing next to Sombra, leading them.
