One light is all you need to free yourself from
total darkness
It had only been a week of this hell, maybe more, Twilight lost track. She learned things she never wanted to know, like how it feels to be cut open. Every time Sombra came in he always put on the collar, the waves of pain it gave was enough to pull tears from her eyes, and the fact that she was all ready practically being kill before hand made it all the more worse. She was barely hanging on to herself, but she had a plain. After Sombra claims her body he will most likely destroy her soul, or banish it, but she had to get out of there! Even if that meant leaving her body behind. Over her time here Twilight was able to pool some magic within her for when the time comes to escape, and it seems like it was today.
King Sombra entered but he was not fallowed by Hope, which means it was now or never.
Sombra looked at his captive, her body was battered and bruised so greatly that he knew it was time. Her bones have been broken into powder, her fur a bloody mess, her horn creaked at multiple locations, scars ran up and down her whole body. But her eyes still burned with pure determination and strength, though not for long.
Shadow tendrils exploded from the ground and wrapped around Twilight and started to go into her mouth and eyes.

Twilight was surrounded by black, as more pain then she ever felt corsed through her body, the tendrals were trying to pull her vary essence apart. Though they were now in her body, where the magic blocking ring has no effect. She blast a wave of magic through everything, as the tendrals recoiled she bolted through the darkness. More tendrals formed and tried to grab her but she was in home turf now, nother could mess with her here, expessialy with the pool of magic she had been saving the whole time she was held.
She felt the shadows take over her body as her spirit ran to the only safe place left, the centre, where everything flows through, the greatest area of magical power. That's where everything was pooled, her magic and the spell.
When she got there she charged straight into the centre of it, not a single shadow could or would fallow her there. She charged the spell and it over took everything that tried to block it, as her soul fled her body. Sombra watched as a glow appeared around her body and disappeared just as quickly, he knew what that was. And he knew he choose well. With the vessel ready he just had to insure that the soul can never return to the shell.
There was only one person that could hold the chosen case, the only one that was alone with her.

Twilight looked around, everything was pure white, crisp and clear. It worked she escaped then she heard it.
"Maybe if I just get rid of this thing."
"No you can't. You promised."
Things moved fast and thankfully, Hope Shard got out through the portal. Twilight focused her magic and thought of the Canterlot thrown room. And in a flash of light they were safe.
