This is a collection of stories set within my personal variant of the Transcendence AU from tumblr. They're more along the lines of experiments. Chances are I'll often go back and edit, maybe even rewrite, a bunch of these every few months or so.
He could still remember the pain. The pure, indescribable agony which had come with the death of Bill Cipher; pulsating, aching in his bones and spreading through his blood like wildfire; he'd passed out, unable to process it, or he would have, if it allowed him to be unconscious. He found it was impossible to ignore that kind of suffering, even with the most severe of biological responses backing him up. Cipher, invading his mind and almost kicking out his very soul from Dipper's own body, attempting to possess his body forever, the strain of retaliating, of keeping—him—out. Dipper thought he would die. Dipper fell to his knees as the dream demon perished, not quite there anymore, simply letting whatever was going on go on. He could see Cipher, when his eyes rolled back in to his head; could feel him disintegrating from existence. The most trying ordeal of his life. 'Difficult' was not a strong enough word. The first death he ever witnessed and it wasn't even a human.
Dipper clutched at his arms, crossed over his chest. His back pressed against the cot he lied upon, he'd been sent to the E.R. of the nearest hospital to Gravity Falls. He didn't know what excuse had been given for his condition, for all he knew he was being toted as a victim of some angry bear's advancement. He didn't care, whatever was said about him, he just wanted to sleep. He couldn't, though, his brown eyes were wide and staring at the white ceiling above, the scent of sterility flooding his nose, giving him a sense of the surreal. Was he truly here? Was it really all...he was battered and bruised, sides slashed to bits, who could have guessed the levels of violence a demon would resort to in their darkest hour. He'd almost been certain there was internal bleeding, not because of any hard fall he'd taken, of everything he'd gone through falling from a great height was not one of them. No, he was convinced of internal bleeding because he could sense it, experienced the insane frenzy Cipher succumbed to while partially inside of him.
However, when tested and examined by professional doctors, it turned out that there wasn't any internal bleeding. He was hurt, but not fatally so. Cold cloth was placed over his gashes, to stem the pour of blood, then bandaging. He was told he was in shock, he had no reason to disbelieve the nurses; he sat there listlessly. His friends and family were alright. Why wasn't he more relieved? Cipher was gone. Never able to threaten a person again. But something was amiss. He hadn't the slightest clue what. Something was blank in his memory—something big. The throbbing headache in his skull didn't help. He attempted to no avail to think, to uncover what seemed to him the last great mystery to solve—what else went down while Cipher and he battled for dominance in a frail twelve year old's body? Dipper's fingers curled, his knuckles became white; what, where, why? Questions. He hoped he'd be done with those. Evidently not.
The doctors finally allowed for visitors some odd hours later; Dipper tried not to be too bitter at them for keeping his own sister away from him for so long.
