*********************************************

   Error coughed as the action of the old, rusted door closing behind him kicked up clouds of dust, his torch flickering faintly for a moment.
   The hallway in front of him was shrouded in darkness, with only the cracks in the ceiling and the dim torch in his hand illuminating his path.
   The structure surrounding him was old and abandoned; almost ancient-looking, if he were being honest.
   He shrugged, trudging along the path mindlessly until he reached a large room, which was pitch-black, save for the light produced by his faintly glowing torch.
   The glitch wandered to the center of the room, his scowl twisting into a snarl of frustration due to his virtual blindness.
   Then...

He was standing behind a large pine tree, his form concealed by the thick fog around him. A muffled voice sounded from not far off, just before it was cut off by the sound of a blade striking against bone.
   A red scarf, tattered and faded, fluttered through the wind and swooped in front of him, and he caught it, looking at the dust-covered fabric with confusion.
   "W̷h̷o̶.̶.̴.̸?̷"
As he lifted his head to look around, everything suddenly cut to an empty, white space, easily identifiable as the Anti-Void, where Error had made his home.
   In the center of the blank space, however, was a vaguely familiar shape; a skeleton, much like himself, but with regular white bones instead of his abnormally black ones. He was wearing a white jacket, black shorts, and the same, tattered red scarf that he clutched loosely in his glitching hands.
   He approached the figure cautiously and, just as he was about to reach out and touch him, he looked up, his right eye socket melted and deformed, and his left one glowing with an icy-blue light. Blood trickled from his mouth, pooling at his feet.
   "P-Pleassse... H-Help me..."

   Error snapped back into reality with a gasp, his eye sockets filling up with 'ERROR' text. Once his vision cleared, he realized that he was still in the large room. Shuddering, he speedwalked out of the room, heading into another dark hallway.
He wasn't sure what the vision was, or what it meant, but he sure as hell didn't want to stick around and find out.
All he knew was that the image of that strange skeleton was burned into his mind, though he wasn't sure why.
He'd been wandering down the path for a little bit before he stumbled across a smaller room, lit up by the silvery light of the full moon outside, which shone through the small holes in the ceiling.
   Just as he set foot in the room, he was hit by another strange vision of something... either long forgotten, or yet to come.

   The words exchanged between the Sans and the short, dinosaur scientist were all a blur as the skeleton tore off further into the sprawling catacombs of the True Labs. Error followed wearily, his own curiosity getting the better of him.
   The Sans paused next to a refrigerator, opening it and pulling out a single vial of glowing red liquid. He grabbed a syringe, which was lying on a table next to him, attaching a needle to the end before drawing up the contents in the vial.
   He wasted no time in jabbing the needle into his arm and pressing down on the other end of the syringe, injecting the substance into his system.
   The burning pain that resulted was nearly instant, and he strained to keep himself together, both mentally and physically. He was gasping for breath, barely able to stop himself from crying out in anguish.
Error watched, his eyes narrowed. The other Sans didn't seem to notice him... Until the world around him dissolved into the emptiness of the Anti-Void, and he found himself facing the same, white-jacketed being from before. As he made his way towards him, he reached out a blood-covered hand, which Error flinched back from.
   "Y-You know... Y-You know what h-happened..." The being groaned, just before the empty whiteness faded.

   Error hissed, smacking the palm of his hand against his skull to clear his mind. He hadn't been in this damn place for even five minutes, and he was already going crazy.
   His thoughts trailed off, suddenly realizing that he didn't actually know how long he'd been wandering. He took a moment to ponder it before shaking his head and continuing on, ignoring the dull ache that had begun to throb within his chest.
   He couldn't help but think that the strange, white Sans in the Anti-Void was a bit more familiar now... But again, he wasn't sure why...
The glitch found himself in another small room, similar to the one he'd just been in. He glanced up, his vision slightly blurred as he fought against the gradually rising pain in his chest. He stepped cautiously into the room, and the vision instantly forced its way into his mind.

The Sans's form was beginning to melt, the liquid Determination in his system boiling him down from the inside out. He gasped for air between soft groans of pain, his body shuddering and convulsing in response to the substance.
Error gripped his own chest, wincing at the thought of how much pain the other Sans must have been in.
But, the scene didn't stick around for long before it melted away into the Anti-Void once more. The pale Sans staggered towards him, his arm tightly wrapped around his midsection, the white sleeve of his jacket stained red.
"P-Please... T-Tell me you're n-not in my imagination..."
Error backed away, his hands raised defensively. "S̸T̶A̸Y̶ B̶A̴C̷K̶!̷"
"PLEASE! I'M SO FUCKING LONELY! PLEASE TELL ME YOU'RE REAL!" the Sans shrieked, his voice cracking with desperation, just before everything faded.

Error forced himself to pull his thoughts away from the chilling vision, and he found himself panting a bit once he finally managed to snap out of it.
He rested a hand on his forehead with a chuckle, becoming aware of a slight, throbbing pain beginning within his skull. "H̵e̶h̷.̸.̵.̶ ̵I̴ m̶u̴s̸t̴ b̸e̴ ̸g̸o̷i̴n̸g̷ f̵u̷c̵k̵i̷n̶'̸ n̸u̷t̵s̴.̷.̸.̴"
   The glitch sighed, hurrying out of the room and making his way towards another hallway. The pain in his chest was slowly growing worse, and it took everything in him to ignore it.
   He walked in what would have been silence, had it not been for the glitched voices whispering softly in his corrupted mind. Though, he'd admit that the voices were rather comforting in the situation. Sure, they weren't helping him with his escape, but at least they served as a decent source of ambient noise.
   He kept walking until he came across another large room... or it could have been the same one from before... He really wasn't sure at this point.
   The sound of static filled his skull as yet another vision came at him.

   Error was positioned behind a golden pillar, watching the fight unfold before him. Sans was at his final attack, firing millions of blasters over the course of merely a few seconds.
   The shape of the murderous child he was battling slammed from wall to wall, just before Sans let them down.
   The same dialogue from every classic timeline rang out through the hall, and Error chose to simply tone it out. He'd heard it enough to know it by heart.
   And then, the sound of a knife against ribs tore through the silence. At that instant, the world glitched, and once again, he found himself back in the Anti-Void.
   The white-jacketed Sans was clinging desperately to Error's stitched-up coat, his breath gurgling faintly as blood poured from a large gash across his midsection, which had previously been covered by his arm.
   Error struggled, but couldn't convince his body to move. He just stared down at the figure, a hand tightly clutching his sternum as his corrupted soul pounded frantically in his ribcage, with such strength that it was actually starting to hurt him.
   The Sans looked up weakly. "I-I'm fucking losing it... P-Please... Y-Ya gotta help me..."
   Error flinched as the skeleton's body seemed to stutter with glitches, his form suddenly flickering to something all too familiar for just a brief instant. Panicking, the dark skeleton staggered away, leaving the gore-covered Sans to topple to the ground.
"S-Stop! D-Don't leave me here alone! P-Please!"

Error gripped his skull with one hand, staggering about before his shoulder slammed into a large, cracked pillar. His body began to glitch uncontrollably as he mindlessly bashed his head into the pillar, gritting his teeth as he fought the urge to scream.
That mysterious Sans was becoming more and more familiar by the minute... And the thought of figuring out the meaning of these damn visions was strangely terrifying.
   A voice within him was pleading for him to just ignore it and get out while he still could, but the urge to uncover the mystery was becoming too much for him to handle.

   He saw the white skeleton once more, but he had his back turned to him. He could hear the faint sound of either laughing or crying... he wasn't sure which it was.

   "S̴-̶S̶T̶O̶P̸ I̶T̸!̵!" Error screamed, dropping his torch and clawing wildly at his skull with both hands. His tear-marks glowed brighter as he ripped out handfuls of threads from his tightly closed eye sockets.
   His soul thrashed about in his ribcage, fighting against the overwhelming panic that was beginning to take over.

   His body moved with a mind of its own, slowly approaching the crumpled form of the pale-colored skeleton. As he got closer, he realized that the Sans was giggling softly, almost maniacally. It was so, so familiar, but he had no clue why.
  
   Error continued to wail as searing pain began to ripple through him, the source being at the center of his chest. "L̵-̴L̵E̸A̸V̴E̸ M̵E̷ A̶L̴O̵N̷E̸!̵!̴"

The strange Sans began to mumble under his breath, his voice shaking with the effort of choking down his laughter. "So many universes... So many anomalies... So many dirty glitches..."

The corrupted skeleton threw his head back with a shriek, his spine suddenly beginning to snap and twist, his body contorting backwards in a direction it wasn't meant to go just before he collapsed to the floor.

   Error was within a few feet of the skeleton by now, his gaze fixated on his shuddering form, unable to be pried away.
   The Sans whipped around suddenly, the right side of his skull melted and deformed while the other side glitched uncontrollably. "Th-This pain is familiar, isn't it?"

   Error howled in both mental and physical agony as the fabric of his jacket began to bulge, his backbone, shoulders, and elbows jutting against the dark material, his body wracked with never-ending spasms of pain.

"All of this is familiar, isn't it?"

The glitch screamed again, tensing up as pain surged through him, at the same moment his jacket burst open, revealing several massive spikes that had erupted from his vertebrae, as well as across his shoulders and from his elbow joints.

   "Don't think I don't recognize what you're doing."

   Error's eyes shot open, his body tensing as the pain grew worse, working its way down into his legs. He was completely unaware of the tail that had formed at the base of his spine as it snaked out behind him, lashing back and forth with a mind of its own.
   His soul skipped a beat when he looked up and saw that same, half-melted Sans standing a bit further into the room, staring at him with blank, soulless eye sockets.
   "This isn't a false reality... GENO..."
   Hearing the name spoken aloud seemed to completely snap whatever sanity Error had managed to retain, and an overwhelming rage flooded through him.
   "T̷H̷-̵T̶H̶A̵T̴'̸S̸ N̸-̶N̴O̸T̶ W̸H̴O̷ I̷ A̴M̸!̵!̷!̵" the glitch practically roared, his mandible splitting abruptly as his jaw dislocated, his teeth growing rapidly into cruel, dagger-like fangs that jutted out from his mouth temporarily, before his face stretched into a long muzzle and a number of twisted horns burst out from the back of his skull.
   He wailed in anguish, his voice deepening into a raw, feral shriek as he violently yanked at the strings that were coming uncontrollably from his wide-stretched eye sockets.
   The figure disappeared, and he was thrown back into yet another flashback.

   The image of the white-jacketed skeleton reappeared, still hunched over on the ground. Soft giggles could be heard from the Sans before it erupted into laughter, and then to helpless, maniacal cackling.
   His voice became heavily glitched, and ever so slightly deeper in tone as scattered pixels shrouded his body. Error could only watch in fear as the skeleton's bones began to change color, his skull, neck, and hands turning black, his legs, feet, and both his eye and nose sockets turned bright red, while his teeth, fingertips, and the outer rim of his left eyelight turned golden yellow.
   His clothes changes as well, the red scarf around his neck darkening to a deep blue shade, his jacket turning to a gradient black and blue color, losing its furry hood in favor of a golden-lined collar, with various parts stitched together with pale blue thread.
  His shirt turned red, and his blood-stained slippers turned into two mismatched sandals as blue strings burst from his sockets, sticking to his cheeks and giving him Error's trademark "tear stains".
   The nasty slash across his stomach-area healed itself, and the blood finally stopped dripping from the Sans's mouth.
   The glitch staggered away, his breathing escalating as his panic rekindled at the sight of none other than himself...

   He scrambled to his now-misshapen feet, making a sound that was halfway between a groan and an animalistic growl as he violently clawed at his mutated skull.
   "N̵O̷!̶ I̷-̶I̶T̶'̵S̴ N̴O̸T̸ M̶E̷!̸!̴ I̸-̵I̸ H̴A̵V̶E̵N̴'̵T̶ B̴E̸E̵N̸ T̶H̸A̸T̴ P̶-̴P̵E̷R̸S̴O̸N̶ I̸N̵ A̶ L̴O̷N̸G̷ T̸-̷T̷I̶M̴E̵!̸!̴!̴" He threw himself against one of the pillars, dragging his razor-sharp claws down the ancient stone with the sound of nails on a chalkboard.
He remembered. The memories of his past life flooded his skull, crashing down on him in waves. Every single flashback... They all fell into place like puzzle pieces.
The glitch shrieked horridly, his legs giving out from under him as he collapsed on the floor once more. The image of that lonely, white-jacketed Sans that had barely been clinging to life resonated in his mind, flashing in and out of his thoughts like a goddamn strobe light.
He shook his head wildly from side to side, snarling ferally as he tried desperately to get the memory back out of his head. His whole body began to contort as the transformation he'd been forcing back finally took over.
   The strings he'd been tearing from his eye sockets began to tangle themselves around his arms, and he found himself snared up by his own threads. But, no matter how much he mentally ordered the strings to stop, they wouldn't listen. He'd lost all control. His magic had gone completely haywire.
   Through his agony, Error managed to roll onto his front, shakily trying to rise to his feet and keep going, praying he could still escape this god-forsaken maze.
   He barely made it a few steps before he crumpled once more, letting out a beastly cry of frustration. His tail whiplashed across the floor, smashing against one of the cracked pillars behind him in its blind panic.
   "I̶-̵I̴'̵M̸ N̸-̴N̷O̵T̶.̶.̸.̷" His voice was garbled, overlaid by an animalistic growl and an unmistakable static roar.
   His body had grown nearly ten times its usual size, and his back was now scraping the ceiling of the maze. However, the spikes along his spine were not able to break through the cracked roof, leaving his only route of escape to be the exit he'd been searching for.
   He practically dragged himself to the entrance to another hallway, not even making it five feet before he fell unconscious.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Ink stepped cautiously through the doorway, waving the torch he'd picked up in the darkness. His eyelights changed shapes and colors a few times as he glanced around.
He'd walked all the way down the empty hallway, and he made it to a large room. But he stopped dead in his tracks when he heard a low growl in the darkness. "H-Hello...?"
There was a loud scratching sound, followed by another snarl, which seemed to stutter and glitch ever so slightly. Ink crept forward, trying to locate the source of the sound.
   Then...
   BAM!
   A massive, clawed hand suddenly slammed down next to Ink, and the skeleton leapt back in surprise. "Woah! What the..."
   The talons remained splayed out before him, allowing him a chance to really look at them. The claws themselves were golden in color, and there was a gap of red color on each digit before the hands turned to black at the palms.
   Ink only knew one skeleton with colored hands like that.
   "E-Error...?"
   As if hearing its name angered it, the beast suddenly lunged forward, its massive body illuminated by the small patches of moonlight that glimmered in the hallway.
   Its eyes were crazed, gleaming with uncontrolled insanity as it scrambled to get on its feet, a blue-tinted foam bubbling from its wildly snapping jaws in its madness.
   "Error!" Ink backed away, his eyelights turning into two mismatched exclamation points.
The beast was entangled in thousands of glowing blue strings, and it couldn't free itself. It simply thrashed, mindlessly snarling and clawing at the cracked walls and floors of the structure around it.
Its movements were spastic and unpredictable, its whole body gripped with frantic spasms as it tried to rip free from the strings that bound it in place.
   Its eyes were unfocused, its dilated eyelights flicking from side to side, its tail mimicking that same back and forth movement. Its breathing was ragged and uneven, gurgling slightly as the blue froth continued to form at the corners of its mouth.
   "Error... buddy..." Ink's hands rose instinctively, though they did nothing to calm the rabid-looking beast. "...We gotta get you out of here..."
   It continued to snarl between shuddering gasps of breath, its twitching shape still writhing in helpless panic. Ink reluctantly stepped around the beast, trying to move in from behind to nudge it out. It screeched, trying to whip around and lash out at the skeleton.
"Error! Stop! I'm trying to help you!" Ink shouted, though the creature probably didn't hear him over its own static-laced screams.
Angrily, he kicked the back of the monster's hind leg, causing the glitched being to roar. "Well then, move dammit! I'm trying to save your ass!"
It snarled furiously, spraying flecks of blue foam from its slightly parted jaws. It fought against the strings that bound it, howling in frustration as it tried to get away from Ink.
"Error! Jesus Christ! You gotta listen to me!" Ink had barely finished the sentence when the beast's tail came out of nowhere, smashing right into his ribs and knocking him back.
Ink quickly got back on his feet, a determined gleam in his eyes as he rushed at the creature from behind once more, this time shoving his entire body weight into its haunches and forcing it to stand up.
The strings around its limbs snapped, and the beast slowly turned to face Ink, its entire body heaving with each breath it took. Ink smiled nervously, then suddenly darted underneath the skeletal creature, using his smaller size to his advantage as he frantically guided the crazed monster out of the maze.
The beast snarled wildly as it gave chase, barely managing to stay on its feet as it pursued the tiny figure with just a single purpose: to kill him, and bring back the silence he'd once known.
Ink didn't even bother looking back. The shaking ground beneath his feet was the only sign he needed.
After a while of running, a light became visible at the end of the hallway. He picked up his pace, panting heavily as he struggled to stay ahead of the creature behind him.
Finally, he skidded to a halt just as he reached the doorway, leaving the beast to careen out of the entry and into the land outside the maze. Enraged, it whipped around and tried to go after Ink once more, but the door had already slammed shut.
It screeched, curling in on itself and digging its cruel, sharp talons into its mutated skull as it realized that it was, once more, alone.

   Woo! That was fun, wasn't it? XD
   Also, there might be a sequel to this coming in the future... :0
   I will be posting another version of this (hopefully) before the end of the year. That all depends on if I get it done or not. :P
   Anyway! Hope y'all have a merry Christmas! And to those who don't celebrate Christmas, happy holidays!
   Don't be afraid to leave a vote and/or a comment! Each bit of support I get absolutely makes my day! <3
   Love you!
