    Summary

    "We are strangers, you and I,
    What makes us different from who we once were and will never be?
    We are no longer the same, it is a fact,
    So why does the pain remain the same?"

    ★ ★ ★

    Error has spent his life trying to forget Ink, the one he once believed was his everything.

    Now, nearing his 30s, he is ready to fulfill a promise that will finally allow him to leave the past behind. But fate has other plans, and an unexpected reunion could either rekindle the flame or destroy it all.

    Nothing is as it seems, and a secret kept for years could rewrite their entire history.

    Will the love that once bound them be enough to heal old wounds?

    Or will they continue to pretend they are strangers?

    Summary

    He didn't manage to even get four hours of shut eye before waking up from his nightmares. So he was pretty out of it. He even had to slide down on his bottom on the second half of stairs just to not risk falling down them.

    He made it to the kitchen with, of course, difficulty. Falling over one of the bored games, he and his best bruh played a few nights before. He mentally noted to fix the mess he made once he finally got what he was aiming for....Wait, what was he even looking for again?— Right! His life-saving substance! Coffee!

    He checked the fridge for one of his outerbucks, letting out a quiet, desperate whine once he saw there wasn't any. Extra work. Great.

    Summary

    The Multiverse is vast and nigh infinite, possibilities, concepts, the very function of a world's reality only limited by sheer creativity.

    Within this realm, Dreamtale exists as an enigma, plucked from another Multiverse entirely. The tragedy of it's Story forced to continue beyond it's Endings, for it forced the concept of Balance into the Multiverse's rules. Now open-ended, the only two Characters wanders throughout the Multiverse as one of it's Outcodes.

    Dream broke out of stone to one colorful and curious Inkblot, so much to comprehend for someone so small. But alive nonetheless.

    Nightmare woke up freshly dead.

    Au: Get it? Cuzhe died lmao

    Summary

    Another day dealing with his brother

    Another day he gets left behind

    Another day and he's room is being occupied by another swapped variant

    ..

    Wait why is there another him in the stars base???

    ____

    Ink and Dream abandoned Azure in another collapsing AU but when he returns to the base, he finds his area is occupied by another him but smaller and looks like an absolute nuisance with how much positivity is radiating off him (makes sense why Dream would pick him for his energy)

    He goes to talk about it with the others of the group, but it turns into a big fight which leads blue to be trapped in an isolated AU left to die till someone from the shadows goes to pay him a visit
    ___________

    Summary

    Mind him, it isn't his fault Murder decided to be a bitch this early in the day.

    Killer—
    Doesn't answer.

    Water ripples against his knees as Killer moves, not just testing the water or rubbing away at Sans’s legs but— he…joined in.

    The silence is even louder than the screaming of the dead.

     

    Or, 5 times Horror Sans noticed they're sharing bath times, just hanging out. And 1 time someone else familiar took the role.

    Summary

    Deep within the belly of the Omega Timeline rests the Underground.

    Not to be mistaken with the Underground— the forced sanctuary settled beneath mountain top: The setting for a story told many a time. No. Deep within the churning, hollow soul of the Omega Timeline rests the True Underground.

    And, nestled deep within the pit of this chasm, rests a fight club.

    Palette knows it as his second home.

    Or: Hidden deep within the Omega Timeline, there exists a fight club and black market. Years ago, a sick doctor created life from little more than abandoned magic. Gradient escapes. Palette waits. Dream is faced with echoes of his past. Ink claws for his identity. And, Nightmare steps into the light once more.
