Error is sick of hearing two sides of one problem that could easily be solved. So, he takes matters into his own hands and gives a little gift to Nightmare. But he isn't selfish, he makes sure that Blue will enjoy it as well. In fact, Blue will thank him later. Assuming Blue isn't still a little... tied up.

Summary
After a forced extended break from writing (crazy how like a week is considered an extended break to me rn 💀), I found myself having a hard time getting back into the rhythm of things; I've also come to take more notice into how I struggle to write flash fiction.
So, I decided to take a crack at the solution by writing flash fics to revive my pace! And what better way to show my appreciation to some frequent commentors than to gift them?
Probably will end up being a reoccurrence if I find myself slumping, so lets see how far it goes! :)

Summary
Nightmare (passive) Guardian of Negativity would say he was a patient skeleton. He did his best to extend kindness and uphold the golden rule. That being said he kept soft but ready and rickrolling people in his brain was pretty rude. In this moment he was just trying to have a sweet moment at last with his brother after so long of them being apart. Also whether or not he would admit it he wished to slightly mourn the strawberries he knew he wasn’t getting.
BUT INSTEAD he, Nightmare (passive) Guardian of Negativity was brought to sit criss cross applesauce across from his brother and four other skeletons who he didn’t know.
(AKA, Dream, Cross and the Bad Sanses are given the opportunity to enter Nightmare’s subconscious in a last ditch effort for Dream to save his brother but of course nothing is that easy and what do you do when you’re in the mindscape of a silly little guy trapped under corruption?)

Summary
The summer solstice is an important day to the worshippers of the sun god: Lord Dream. The preparations must be perfect or else their quaint village will suffer under his wrath. The already strenuous preparations are made even more stressful when the demon, god of the moon, Nightmare, sends his wraiths to the village, destroying and wrecking havoc within. The inhabitants are at a loss of what to do, but they simply keep going, as it's Lord Dream's will.
One man won't take it, though.
Blue.
While he isn't blessed by Lord Dream (something he wants but will never admit), his loyalty is to the village and his friends, and he'll do anything to help keep it safe. With the solstice drawing near, he makes one desperate decision: to bargain with the King of Night.
Will it be enough? Will he get Dream's blessing? Will he die in the attempt?
Or will he discover something that he wasn't meant to know?

Summary
The Guardian and Protector of Positivity, Dream, is a simple sort of spirit who just wants to keep people alive, safe and happy. When his brother and fellow Guardian, Nightmare, is corrupted by the magic of the Tree of Feelings, things begin to be a little more complicated. They are forced to flee the village they spent their entire lives in and learn that the world is far more immense than they ever could have imagined.
When a kind (and vaguely suspicious) stranger opens their doors to them, the twins find themselves apart of something much bigger than themselves, a puppet show where everyone is trying to pull the strings.
After all, the only thing that matters is that the audience is entertained.

Summary
Drip...
Drip...
Drip...
The skeleton looked up to the ‘sky’... If you could call it that. He was currently in Waterfall, watching the rain drip from the stalactites? Stalagmites? He could never remember which went up and what went down. It didn’t matter much anyways.
Soon he’d head home, as was typical. He was just taking a break before he left Waterfall to go to Snowdin- He had just finished training with Alphys. Today she had him cook again- he hardly ever got to do battle training anymore- the reptile thought he couldn’t handle being in the guard. He never mentioned it to her- it’s just how their world worked. It wasn’t his place to change that. He’d stuck close to his original code after being introduced to the Multiverse and Star Sans’.
After all, he didn’t want to worry his friends or get them involved… It was bad enough that Nightmares ‘gang’ could track down his home world. Though, for specific reasons, he wouldn’t complain if they did.
He couldn’t be thinking of that now though. There were more pressing matters.
