Twilight's body changed, she passed out from the changes. She looked very similar to her old self, however there where white 'cracks' going across over her chest area. Emitting a glow of white light. Her eyes emitted a white magic in a similar way that Sombra has his amethyst colored magic flowing out of his. Her cutie mark changed, the purple stars on her flank where white instead of purple. Her eyes seemed to shine through her closed violet eyelids, her horn ended with a bit of whiteness, aswell as the feathers on her wings ending with much the same.
Sombra immediately looked away from this, he hated seeing the light. He always thought light was his enemy, did he just create his worst enemy? Unfortunately for him, probably. But he could still feel a good degree of evil within Twilight. Did he just make Twilight sparkle an evil light pony? He didn't know, but this was not how he wanted this to end up. He unchained Twilight from the black crystal alter and picked her up. She felt just so light to him. A part of him felt that she was...cute. Although he wouldn't let that get to him. He had another plan.
He walked down a passageway to another part of the cave he was in, this was his base of operations, far below the icey wastes where nopony would look. He was going to attempt to mind control Twilight. He looked around this other part of the cave, looking for a...stasis chamber of sorts. He placed Twilight inside of that, she froze still, not making a single move. She was totally under his whim now. He knew for sure that this time there is no way he could possibly lose, but he won't let that get the best of him. He just hopes Twilight won't be uncorrupted / uncontrolled or turn against him somehow.
Sombra's horn glows a deep purple, and a purple beam hits Twilight. He starts taking control over her, Twilight whimpers in her sleep as this happens. Once that is finished he takes her out of the chamber, and wakes her up. Twilight stands next to him. Ready to take orders from him. He tells her of his current plan: Take over the Crystal Empire, and free the umbrum.
He cannot do that himself this time though, as he knows Cadence and Shining armour would be prepared for that. With Twilights understanding of magic, they will fall this time. Twilight looked at Sombra with a look of admiration in her eyes. He grinned and gave her some knowledge about his dark magic and some of his spells, such as turning into smoke, and opening up his sealed and hidden staircase. Only him and her will be able to open it, he also tells Twilight the way out, and says that he will be here waiting for when she returns. He orders her to leave for now. She complies, no questions asked.
Sombra cackles, and vanishes into the darkness. Twilight finds her way out, it takes a good deal of time for her to leave, once out she is encountered by the numbing cold of the Crystal empire's winter. She puts up a barrier and starts heading towards the crystal Empire.
Twilight was in a deep cave system one day, exploring the depths of the deep dark caves. Little did she know this would be her downfall. She felt like she was being followed, she looked around to see who it was but didn't see anyone until the last moment until she blacked out suddenly. Seeing the corrupted eyes of King Sombra. She had no help this time. How foolish of the little princess.
She awakened tied down to a black crystal alter of sorts, purple and green flames illuminated the dark cave. King Sombra was standing over her, this absolutely horrified her. "Hello Twilight...." he said to her, his voice dripping with corruption and darkness. Twilight was stunned and in fear.
"Such a strategic mind...defeated Discord...Nightmare Moon...Tirek..." he says with an evil grin. "Even me...but not this time..." he said. Twilight felt something on her horn. Black Crystals. She also saw her element of magic with black crystals imbedded on it.
"Your time of having this is over..it is mine now...so are you Twilight..." an evil cackle resounded through the cave, it echoed quite loudly. Twilight knew nopony would help her this time.
Twilight started to hyperventilate. "Sombra...why are you...doing this to me...? Why me...?" Sombra grinned evily. "Its the way things are meant to be..." he said, his horn glowing a deep red, blood red. Twilight had never seen anything quite like this. She didn't see King Sombra so talktive before.
"Sombra...please....don't!" Twilight screamed. Sombra didn't reply to that, the deep red glow surrounded Twilight, she could feel her mind and body changing in a way.. she was becoming something she never wanted to become. Something equestria who
She tried her best to resist this. Sombra was penetrating her mind, she was resisting fiercely, she was the element of magic afterall, but that wasn't going to last forever and she knew that. It took a few more minutes until Twilight finally gave out. Sombra was much stronger than she anticipated, and that was her downfall there.
Sombra's 2nd coming when he was blasted to bits was nothing but a test to gauge the power of his opponents. His 'death' was a complex illusion, he now knew the spells they used against him, the ponies who are against him at the current time and who they are, and now he is prepared for his 3rd coming. With Twilight at his side nothing can stop him. However the effects of this spell weren't replicating Sombra's ways of corruption, they were making Twilight's evil side come out. She was going to be a great asset for King Sombra and a grave threat for the forces that oppose him. Equestria will feel the wrath of the tyrant king, with Twilight by his side. Celestia's mistake.
