Stolen Power {an UNDERTALE fanfic}

Chapter one: what have i done

Frisk's eyes close slowly as she fell asleep. Hoping another nightmare wouldn't come to torture her in her rest.
Toriel quietly shut the door, leaving frisk in peace. And suddenly, she was there. In front of toriel again, a sharp blade in her right hand, and wide grin on her face. She could feel her body moving towards her, not under her control. She slashed at the figure with all her might, leaving a dark streak across her chest. She fell to her knees as she mumbled," y..You really hate me that much..?" Toriel said as she collapse completely, incinerating into a pile of DUST.

Frisk frantically shot up from her pillow. she felt cool sweat trickling down her face. She buried herself in her covers, sobbing and screaming repetitively. Toriel rush to the door, nearly knocking off its hinges. "My child! Are you alright?!?" Frisk look up at her letting out a sigh of relief.

Sans came rushing down the hall and dashed into her room, too fast. He slammed his skull against the wall. He fell backwards and hit the hard ground with a loud THUD. Frisk laughs lightly as toriel rushed over to him, picking up by his blue hood, and plopping him down on the ground.
"F-frisk are you *pant* alright? *Pant*" Sans asked. "I'm alright, it was just..... A nightmare..." Her voice quieted as she finished her sentence. Sans stared at her startled. "Another one? Geez kid you seem to be having nightmares every night now."Sans said, a concerned look on his face. Toriel started to speak"well if everything's alright then I insist you get back to sleep. It's almost midnight for heaven's sake!"she said gently but impatient."okay Mom... But um, Sans?"
"Yeah kiddo?"
"Could you umm... Stay with me tonight?"
She asked quietly.
"Uh, sure kid.."
Sans said as he stepped over to a cushioned Chair by the bed.
"I'll be right here" he said as he sat down. Toriel smiled, then made her way down the Dark Hall, swaying the door behind her, leave it open just a crack.

Frisk slowly doze off, but Sans, being very startled by the incident, stayed awake for quite a while. After about an hour, he decided everything would be fine, and set his legs and back on the arms of the chair, his head laying on the pillow on the opposite side of the bed.
Thankfully frisk who was sleeping peacefully, had a wondrous dream. She was rolling around on a luscious Green Hill, playing among the golden flowers and the buttercups. She suddenly saw Sans dozing in the flowers a few feet away from her. She playfully decided to roll over to him, unaware of this was causing her at her to actually roll over on the bed.

She spun until her hand swung around, Landing forcefully on Sans face. Sanses eyes open slightly, and being very startled indeed, his left eye turned a bright neon blue. Frisks hand barely twitched but one of her fingers moved ever so slightly. It swiped directly through the path of the blue smoke like substance rising from his eye and.....

BAM

An enormous wave of electric shock shot through her body. She shot up from her bed so fast she swung around and slammed against the hard floor. She was barely breathing as tears streamed down her face.

She was shaking rapidly. Sweating her eyes wide and full of tears. She resisted the enormous urge to scream, hoping she hadn't woken Sans. But of course, he was fast asleep.

She crawled over to the wall, barely able to move her arms. She thought about resetting, but soon remember the promise she made to Sans. She could never break a promise, especially one that meant so much to a dear friend. Another shock of pain shot through her upper body, violently tearing at her skin and nerves. She leaned against the wall gasping for air.

Her eyes directed across the room to the other side to see a large broken mirror. The shards of it splattered around could barely give off her reflection, but in the corner of one of the few shards still on the frame,

She saw it.

Her eyes.

They were pools of black tar. Blacker than the night sky. In the center of her left eye the neon blue smoke rising from the bright Circle in the middle gave it away.

She had absorbed Sanses power.

She couldn't help it. She screamed out in pain as a blue light penetrated her. It hurts so bad. She buried her face in her knees and she screamed in pain once more. San's awoke in a panic, rushing over to her rapidly, but she refused to let him see her face, or look at him at all.

She felt herself being picked up and carried. She was set down on her bed, but she shut her eyes as tight as she could. She was shaking so badly. Frisk felt a cool bone finger stroking her face gently, but she didn't open her EYES.
