Summary
Like most nights, hung with plastered stars and moonlight, Error isn’t sure how it starts.
One moment, Error was content, eyes focused on a new knot of string, fingers gliding through the air like puppeteers, sitting at the edge of his mattress. Then the next, Nightmare was before him, fallen to his knees with a sunken desperation to his face. There was an unmistakenable shake to the man’s eyelight— a candlelight in the dampened bedroom they shared.
Trembling, the man had planted his fingers onto Error’s knees and whispered his name with sacrary.
“Error. I need you.”

Or, Errormare finally let themselves free from their battle of control.

Summary
The world has always dealt in absolutes. It was absolute when it took Error's parents away from him, leaving behind three siblings with nothing but each other to rely on. It was absolute when it coaxed him to become something greater than himself, fueled by the pain and desire to right society's wrongs. It was absolute, when it decided that Error was the king in life's extravagant game of chess.
Or, Error is a friendly neighborhood vigilante until he's not.

Summary
I've been obsessed with the song "Andrew in Drag" thanks to a video I stumbled upon on Tumblr with ErrorInk. The video is by pinkcottoncandyss and it's beautiful and amazing and this song does wonderfully terrible things to my chest. I'll try to do both justice, but all I can do is try.
Okay so pretty much, Error has two friend groups: The Star Sanses, and The Bad Guys. In this story we're just gonna make things easy on me and act like everyone is kinda normal? Anyway, so "the bad guys" are a little more rambunctious, and Error loses a bet and has to perform drag on a stage and stuff. Well they invite "the star sanses" for shiggles and gits, and Ink is like "holy fuck" get it? I'll also be including some "excerpts" to try hammering home the longing aspect, including how the two groups met (through dream and nightmare)
(also I'm using the name Blue for Swap Sans even though I would prefer to call him something else in my stories, since this story is kinda different from my other stuff) (Everyone is a little out of character, cause I'm trying to fit things to the song a little bit more, if that makes sense)

Summary
The war against Nightmare has come to an end.
Negativity has receded. The multiverse can breathe again.But some battles do not end when the final blow is struck.
Stripped of the entity that turned him into a symbol of terror, Nightmare awakens in a reality that rejects him, fears him, and watches closely for the slightest mistake. To many, nothing has changed. To others, he is a threat waiting for an excuse.
As the multiverse struggles to reorganize itself, Nightmare is forced to face a role no one wants to name: negativity still exists, and someone must guide it.
Between the council’s reluctance, the quiet support of a few, and the intimate bond that emerges between him, Killer, Dust, and Horror, Nightmare learns that surviving is not the same as being accepted.
This is a story about what comes after the war. About guilt, prejudice, and balance.
And about continuing to exist when the world has already decided who you are supposed to be.Bookmarked by Tacol0ser

Summary
Life had been... good...? Dust hesitated to call it that, because whenever something was good, it'd inevitably go terribly, awfully bad.
And it did. Horror had gone missing one day, without a word and without a trace, leaving Dust all alone.
Until, of course, he found him in a random AU, content and... living his best life. He felt indignant, abandoned for another version of them that wore a fucking sunhat, for crying out loud! So he did the most logical thing he could; pretended to be a Sans from a Fellswap AU so he could be with his lover again, if only for a little while.- Language:
