Daybreak [ Error!Sans x Reader ]

11. Pulling the Strings

"You've grown weak!" [Y/N] shouted from below, Error circling ahead on top of his blaster. "When the wheel turns and I take your place, I won't make the same mistake."

"Power is arrogance," Error chuckled as the blue strings wrapped around [Y/N]'s ankles and around their [S/D] coloured soul that beat against their chest. "That is the difference between the two of us. When your power grows, you must learn to control it, not use it. If there is no discipline there is nothing but foolishness."

The blaster floated towards where the human was suspended in the air, gaping jaws ready to fire off another laser should the instance require. "You are not my successor," Error growled and pried the knife from [Y/N]'s grip. The human shrieked and gave way to a fit of convulsions, no longer in contact with the bit of soul buried within the confines of the weapon.

"Kill me!" [Y/N] spat, eyes laced with their own fury and insanity. Error was vaguely reminded of the first days he spent alone in the Void, alone, screaming and begging for some listener to kill him. But then the screams had started to scream back until all they ever did was scream and scream and scream and...

What was he talking about?

"Too much work," Error muttered and looked at the knife. If he were to destroy it, [Y/N] would consequently die, no question about it. And following their death would mean Nightmare's abbsolute victory, something that neither Error nor anyone else could afford. But the carnage of Underfell was already proof enough of the calamity that would follow should the soul weapon continue to exist, and the fact that [Y/N] would be driven to near insanity with an incomplete soul and thus be incapable of fighting.

The third option was inconceivable and yet perfectly rational at the same time, the true and only option at hand. While [Y/N] could not function completely with a missing part of their soul, it was possible for the soul to be patched.

Error closed his eyes, wondering if this was the best option. There were unthinkable consequences should this follow through and perhaps [Y/N] was right, maybe some poor bastard would be deemed his successor by the invisible balance that dominated them after all. But this was necessary, vital if anything. Whatever brought him closer to watching last night's episode of Undernovela in peace...

"Human souls are complex," Error explained, refusing to meet [Y/N]'s empty eyes. The human seemed to be in a vegetative state, neither fully present nor comatose. After having been exposed to the other half of their soul for so long, it seemed that their body could no longer sustain itself with only a partial soul. "But that doesn't mean they can't be altered, if even the slightest."

He brought his own soul into display. This was essential for the war at hand, essential for his own preservation so that Nightmare would finally be eradicated and Error could once more resume his plans of deleting the universe. Or perhaps he would uphold the truce between him and [Y/N], content that no universes would ever again be created. This was why he was doing this, nothing more. There was no other reason for him doing this, at least what Error attempted to reason. This was necessary.

There was no other option.

Error brushed the tip of his finger along the left half of his soul, a black and glitched thing that embodied everything foul in the world. Looking away, he snapped off the piece, biting back the agony and pain that ravaged his form as every fibre of his being threatened to wither into dust right then and there.

Quickly, it was essential to act quickly. He placed the broken half of his soul into the missing portion of [Y/N]'s own soul, watching in satisfaction as the two pieces reacted, medling so that they formed one complete soul. It was a queer sight, one half being the ebony black of Error's soul and the other half being [Y/N]'s own original soul.

But now that [Y/N] owned a complete soul, Error could now repair himself. The soul weapon could now be destroyed in order to obtain the soul trapped inside. It would no longer harm [Y/N] when broken because they possessed a complete soul, meaning they were no long tethered to this half. He grabbed the hilt and blade and snapped the damn thing in two, grabbing the [S/D] portion that flew into the air, quickly shoving it into his missing half.

The portion of [Y/N]'s soul fused to his own, fading to a dark black and becoming indistinguishable with the other half of Error's soul. It looked exactly as it had been before, glitched and foul. There was no idea knowing the long term consequences, but the current way of things required living only in the present where dire actions were required in order to ensure that they could live for at least a second more. Everything was done in small intervals in this war, not caring for the future that lay after this battle.

"The things I do for glitches," Error growled and lifted his hand, carrying [Y/N]'s comatose form in the air behind him. He swiped his hand, opening a rift in all of time and space, bringing the two of them once more back into the Void.

And then that rift closed, leaving behind the grave of Underfell, with its unstable code that collapsed in on itself, fading entirely from existence, living only in the minds of the survivors that once passed through it.

And embodied in the hate that remained.
