    Summary

    Dream stared at the endless white and shuddered against how oppressive this place was.

    His eye lights focused on the only thing here.

    There was a skeleton on the ground with his hands over where his ears would be. Most of the skeleton had turned dark with glitches and the occasional error but part of his face and some of his left arm and torso was still white. He wore the typical Sans hoodie but with different colours and red glasses.

    He was muttering to himself.

    "Are you okay?"

    A.k.a: What if Dream had met Error before he completely went crazy?

    (This fic is inspired by For the Forgotten Ones.)

    Summary

    A knight captain is trying to balance new love with old grief, struggling to differentiate dead limbs from something recoverable. His world is changing, in more ways than he realizes.
    A General is trying to serve too many sovereigns at once. He has to choose a side, in more battles than he knows he's fighting.
    A knight listens, hears, and struggles to puzzle together a greater truth. He feels ineffable forces start to bend.
    A seer is wrought with visions he can't interpret. He grasps at clarity like the sand in an hour glass, lower on time than he realizes.
    A Prince is preparing to become king. When he grapples with his fate, he changes more paths than his own.
    A Queen keeps her silence. When she dies with her secrets, her silence speaks louder than any living or dead man.
    A force invisible as wind and as silent as mice in the night acts, and all is upturned in an instant.

    Summary

    You’re six months into your career as an electrician and for the first time in your life, you’ve got your shit together. Go you!

    When the job brings you to a mansion inhabited by skeleton monsters and your ex-girlfriend, things change. The wiring in the house is fried, the skeletons are suspiciously evasive about the basement, and your ex keeps inviting you for sleepovers.

    You just want to get through the repairs without setting the place on fire. Keeping your sanity intact would be a nice bonus.

     

    Or, another anti-harem fic, but in this one, the girlfriend is into you too.

    Summary

    He raised his head with difficulty. His eyes widened in surprise. In front of him was a portal, as glitchy as he himself, and he could see a dark sky with stars.

    He extended his hand and it easily passed through the portal and on the other side a light breeze blew across his fingers. It seemed that strength suddenly filled his body, and the magic responded with warmth and he literally jumped into the portal, turning out to be on an island that flew among the stars.

    A surprised sigh escaped him before he sank down again, but now it was no longer the white empty floor of void, but I was soft, cool grass.

    Stars, how he loves it here. This place is much better than anti-void.

    Summary

    (UPDATES EVERY FRIDAY. Maybe)

    NIGHTMARE is a sadistic bastard, that's just a fact. His goal is to corrupt Dream's soul and prevent the Doodlesphere from feeling positive emotions ever again. He has a new plan to do it. His brother is smart enough to know his games, but one of his friends isn't.

    INK doesn't know what to think of the letter on his nightstand. It only added onto the strange missing things and nightmares he's been having. Was Nightmare asking him on a date? Pfft, that was ridiculous, there was no way- wait. When did he get so pretty? When did Nightmare get so perfect?

    DREAM has the hope of the entire multiverse in his hands. With their best friend and Protector of the Doodlesphere missing, they have to do both Ink's job and their own, along with making sure no one else goes missing. He's stressed and exhausted, but he can't rest now. Come on Dream, stay . . . awake . . .

    Summary

    new summary:
    A long time ago, a skeleton with black tattoos found themselves alone in a white void, in one story, that skeleton went and became beloved by the multiverse that he protected, but in another, in this multiverse, that skeleton never took that journey, and stayed hidden, avoiding attention, the multiverse remaining unaware of their existence for years and years and years...

    until someone, dream, noticed.

     

    (old summery:
    I always liked the image of ink being a homeless hobo skeleton creature with no sense of shame or social norms, having no idea how to math because they have no actually education and basically clinical insane, I also like to imagine that by following his rule of "don't interfere with the goings on of the multiverse" he would act feral as fuck, So this is exactly what this is, dream and blue basically trying to tame the multiverse guardian ink. but like way more plot based)
