    Summary

    (Swapdream Multiverse with Diabetic Reader)
    Your multiverse was absolutely crazy. Obsessed with the way of thinking promoted by the godlike entity that calls himself Dream, positive emotions and thinking are prioritized and negativity ends up demonized as a result. But you don't really like that way of thinking. Not one to wallow in your own emotions, but your life sucks. Being a diabetic sucks. And you'd like to be able to feel every bit of negativity without being told off, thank you very much (Swan X Reader)

    Summary

    Dream was never known to be fragile and weak; he always seemed to be so happy on the outside...

    Then it happened. He was weakened so much in a sudden amount of time. For the first time in years-

    -Dream's actions would catch up to him, to some fault of his own. There still rages an eternal battle: Dream and his past memories. Nobody could tell something what was wrong...

    At the same time, Ink was afflicted by something too, and Error just couldn't sweep it under the rug...

    Summary

    So I literally never see anything with a diabetic main character and especially not a diabetic /Reader fic. Skeletons are sexy so lets play around with ideas while I get a diabetic reader a harem of their own!
    (I have been diabetic over 20 years and I honestly can't tell if I should be annoyed or amused at my own title)

    Summary

    When Papyrus' daughters want something read to them that has princesses in it, Sans chooses the lazy way instead of coming up with a story. He types princess in the timeline machine and straight reads off a Princess Frisk adventure. After a couple of nights, Papyrus leaves and Sans is in charge of the girls. When he reaches the end of the princess adventure, he knows where Papyrus is at.

    He also knows that their timeline is about to be erased, if he doesn't find his own version of Princess Frisk.

    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

    “It's late, and it's raining,” you state, tugging his sleeve and halting his steps. The smell of smoke is strong, and it mixes with the earthy scent of the night. “Why are you trying to sneak away? You know you can stay for as long as you'd like.”

    He turns around, his figure darkened by the poor lighting of the patio, plus the lack of a moon.

    “solid suggestion, but you and i both know that's not a good idea anymore,” he replies, his voice sounding on the edge of exhaustion.

    Far used to his behaviour – one you've been a witness and victim of for the past few months – you roll your eyes and fetch a candle and a match from your pockets.

    “Oh, please. Don't be silly! You're always welcome here.”

    And as the flickering flame brings about clarity into the deep darkness of the garden, you quickly draw back a comment on him being dramatic.

    He's covered in dirt, and the injured body of a familiar face lays motionless on the floor.

    “just to let you know," he says, chuckling, ”i was only gonna drop this off." He gestures at a small, black box he retrieves from under his suit. "but that was your last chance to reject me, so now the fault's on you, if ya didn't want this.”

    Summary

    When Coffee was small, still in stripes with his thumb in his mouth, he would get the overwhelming urge to run away. He can't recall why, really. Despite knowing the rules that his mother had given him, one day, he ran. His brother ended up finding him an hour later, sobbing silently as he wandered, lost, in the snowy woods surrounding Snowdin. Wine, barely a teenager at the time, had dragged him back home.

    The feeling never dissipated, though. If anything, it worsened. And growing up underground, there isn't really anywhere to run, anyway.

    On the day of his mother's funeral, when he was 10, the itch got worse. Yet, he didn't run and let it simmer as he stood, empty, next to his brother, staring down at the urn.

    Over the next few hundred years, as Coffee grew older, the itch never went away. When the resets started, the itch got unbearable. Yet, with nowhere to run, stuck in that damned cave, he remained.

    Then, he and his brother were sucked into a different universe. A kinder universe. One where Wine wasn't Captain, Coffee wasn't a soldier, and the sun was in the sky. And with the sun hung freely in the sky, Coffee suddenly had everywhere to run.

    Summary

    Frisk has reached the end of the road in their resets and the strain of their timeline finally gives way right before they can fight with Sans.

    In a last minute feeling of regret, they try something unbelievable.

    They relinquish their soul, and the next thing Sans knows he's laying in a bed of flowers, feeling like he was ripped apart atom by atom and then put back together again.

    Also he has hair.

    And skin.

    And this new Underground he's ended up in isn't quite as friendly as he remembered. Great.

    Summary

    How many times has Kris experienced Chapter 1 and Chapter 2? How many times have they risked their life, fought those same people, over and over and over? It had to stop. Eventually, there was a breaking point. Something changed, and suddenly, there was opportunity. There was rage, mania, confusion, horribleness. Kris had become something else. Something unlike anything there ever was.

    In this opportunity, Kris has separated from Susie, and after making her do horrible things not even an hour ago, Kris syncs up back with Noelle. Together, they do everything together, that night. Traveling on adventures consolidated solely within Castle Town, and Hometown.

    Something strange has happened because of all this, however. After defeating just about everyone that stood in their way, Kris and Noelle emerge from the Dark World, to find that a new Dark Fountain has formed at Kris' house, despite never opening one there. Together, the two of them aim to find the creator of the new Dark Fountain, and perhaps indulge in what little this world has left to offer them.

    There just seems to be one problem with that. There's one person left who still poses a threat.

    Summary

    DreamTale had collapsed centuries ago. The great Tree of Feelings fell, died, rotted, decayed. Nightmare had eaten all but one of the apples, the one surviving Golden Apple stored and fused with Dream.

    But what of the leafs?

    What of the blossoms?

    What of the bark and roots that had been pressed and preserved for memories? For old times’ sake?

    What of the little skeleton, not quite a sans, not quite a monster, running around in Nightmares castle dungeon?

    Summary

    Where you, as the reader, are Sans. And your best friend is.. Papyrus? And now theres Sans? And Papyrus? And Papyrus and Sans and.. This guy says his name is Dust? And that guy looks like he's covered in gunk, and why is this Papyrus calling himself Stretch?

    Blurb;

    “Do we call each other Sans and Papyrus?” He beats you to the question the moment you open your mouth, startling a chuckle out of you. You walk over to him, draping yourself over his shoulders with a long-suffering sigh. “I guess I could just call you bro. Are you the older of us now?” You blink, looking at him through the mirror.

    No update schedule, I can barely remember to write. Ill try though!

    Summary

    Chara’s doing fine. She’s perfectly happy existing only through Frisk. She doesn’t miss having a body of her own. She doesn’t care that her family doesn’t know she’s alive. She’s definitely not making eyes at a certain skeleton Frisk has no interest in. She doesn’t mind being alone and forgotten, not at all, not one bit!

    …yeah, she’s not fooling anybody, is she?

    The truth is, Chara wants to live again. But it’s too late for that now, isn’t it?

    On hiatus until March 11, 2024 or until March 18, 2024, whichever of those deadlines I manage to hit first.

    Summary

    The complete story of Lifetale, an AU of Undertale. Destruction occurs (sometimes), but Frisk can always reset it, so... Additionally, there's a potion that freezes age, hence "Lifetale". All of the monsters, as well as the eight humans, drink it at some point.
    This story has 5 parts: the Introduction, or Prologue, the Genocide run, the Neutral (Pacifist) run, the True Pacifist run, and the Epilogue, or Ending, which is written from Asriel's point of view.
