Curing the Darkness {Private with diokno44}
 

A bright light... A bright, loving light... That was all it took. Everything was over. The control... the darkness... the crystals... All undone by those ponies...

Sombra didn't recognize his surroundings. It was dark. It was cold. Chains decorated his legs and around his neck. His horn was broken. He couldn't feel the magic. It hurt just to attempt. Everything was different. Everything was different.

No... No! THE CRYSTALSSSS! H-He needed the crystals! He needed the darkness! No, nono, no! It was all wrong! "Crystalssss... crystalsssss.... CRYSTALSSSSS!" Sombra roared. He fought against the chains and writhed in pure rage. He wanted out! He was a king! He was a god! He needed to be set free! He needed the crystals! The crystals! CRYSTALS!

Eventually... his anger faded. He got himself tired. It was stupid to continue. Sombra allowed himself to become numb to his thoughts. He simply rested on the stone floor, staring at the door of his cell. Someone would come for him...

(Is it alright is Sombra was Celestia's student once and had feelings for Luna?)

Princess Luna trotted towards Sombra's magic proof cell. The dark unicorn had somehow managed to reassemble himself a few miles from the Crystal Empire, no doubt because a piece of him, his glowing red horn, had survived. "Ah, you're awake." She stood I front of the cell.

( Mmm, I prefer Sombra to be a separate entity. I like the idea that he was once, long ago, a fairly kind king, but corruption got to him. He could've known the sisters, and had some feelings for Luna. )

Sombra's blood soaked, ruby eyes stared up at the Princess of the Night without emotion. He felt as though she were familiar... But the darkness clouded his mind. He could not place her. "Crystalsss..." No, words... It had been long since he had engaged in social contact. There was no such need in commanding those worthless crystal ponies. "... ssss... sssssuh... so.... ah... I... aaaaam..." This was harder than he remembered. "Mmmmmy... horn..." He raised a shaky hoof to touch the broken stub where it used to be. "Where..."

"Your body is still reforming itself." Luna said, leaning down, "I came down here for two reasons, one, to see how you were doing." She smiled, "Amd to announce I have appointed myself your rehabilitator." She giggled.

Sombra stared on from behind the bars. He was a king reduced to rubble. A god without power. A shadow brought into the light. This alicorn had the nerve to ask him how he was doing? At the next statement, he narrowed his eyes. Rehabilitator? He was not ill. He was not going to change. "Yyyyou... are... desssspic...able... I... am... Sombra... I do not... require... rehabilitation..."

"Oh yes you will, and we're starting from the beginning." Luna levitated over a foalish pink diaper and changing supplies over, "Trust me, you'll like it." Quickly, she magically powdered and diapered the former dark king. "There we go." She cuddled Sombra. The diaper was enchanted so he couldn't remove it himself.

The beginning? Finally, emotion flashed in those cold eyes of his. Sombra couldn't run because of the chains. He snarled at being cuddled by Luna. His strength was weak, so even as he attempted to push her away, nothing happened. "You... despicable... Release me this... instant."

"Hush." Luna popped a pacifier into Sombra's mouth. She subtly,cast a spell that would not only weaken Sombra's bladder and bowel control to almost nothing, but would also slowly remove the corruption of dark magic.

Sombra growled around the pacifier. Upon Luna's probing of what magic Sombra had left, the stub of a horn he had sparked with black, purple, and green auras. They quickly dispersed. He pulled the pacifier out and tried to throw it. It didn't get very far.

"Don't worry, once your rehabilitation is done, you'll feel much better." Luna giggled, pulling out a bottle of cool milk, and popped it into Sombra's mouth, holding it in place, "Now drink up sweetie."
