    Summary

    There are infinite opportunities in this world. Infinite opportunities for dreams. Infinite opportunities for hopes. Infinite opportunities for regrets... for loss.

    There are some memories you would rather just forget...

    The old royal scientist knew that better than anyone.

     

    BRIGHT, BRIGHTER, YET BRIGHTER. SO YOU STILL SHINE ON, EVEN AFTER EVERYTHING YOU ENDURED. EVEN THROUGH THE COLDEST NIGHT.

     

    But a story doesn't have to end the same way.

     

    EXCELLENT. TRULY, EXCELLENT. LET US BEGIN THE CREATION OF OUR NEW FUTURE.

     

    Sometimes... a game can have a secret ending.

    (A Deltarune novelization that takes some unexpected turns from canon. Based on some theories, and a little bit of imagination, even the unknown can make itself known.)

    Summary

    You may know this song and dance by now, the stories where a creator gets dropped into the Undertale multiverse and makes some skeletal friends.

    More than a few stories exist where a creator is dropped into a 'skeletons stuck in a certain world' scenario.

    Fewer still are the tales of creators becoming skeletons themselves.

    I joined the Undertale fandom a long time ago, but when I started writing down some ideas I had, I never would have expected joining it to be meant in a literal sense, and I definitely would not have expected my sibling to join me on our adventure.
    Now rated T for certain topics inherent when talking about some sleletons' backstories

    On a lazy afternoon during a quarrel with Sans' favorite flowery menace, Sans finds himself in a strange place; a world between worlds that looks awfully similar to the surface and it turns out he's not alone. What begins as a strange encounter leads to even more stranger events that alter the word of Undertale as we know it.

    Enter Rin Tohsaka: The New Heroine, as we follow her descent into this new universe that she'll have no choice but to consider home.

    Summary

    Gaster had became a constant in his life faster than many of his oldest regulars. The scientist will come every morning around 7:30, order a black coffee and leave, no additions and definitely no small talk, always in some kind of auto-imposed rush. it was nice to be able to say hi, but nothing else was allowed, and even there were days where he was actually lucky to receive a response to his greeting. However, around 9:30 in the evening he would show up again, less frenetic and looking more close to be a zombie than a monster made of magic, take a seat in the counter and order the same things, a cupcake and black coffee. And they will talk until no one remained inside but them, and then a little more.

    Summary

    Frisk... really didn't know why she thought the fall would kill her. She was literally made to be indestructible. Falling down some hole while thinking of dying wouldn't really change that.

    And now she's stuck in a random hole down Mount Ebbot.

    Great.

    Wait, except, it isn't just a random hole. It's a random hole which leads to a whole kingdom of monsters. (Only in species, not in the human definition of that. If she went by those standards she would be the monster here, not these painfully naive people.)

    Also, there's a talking voice in her head.

    And also, on top of her bullshit biology, she now has the power to bend time!

     

    Goddammit, why her???

     

    I have finally returned to the Undertale Fandom, and I present to you a complete rewrite of Determined to [SAVE]. Featuring actual worldbuilding, better writing, and an actual plot. Along with some actual defined power for Frisk other than "magic goes woosh".

    Summary

    It's... Not really what you had in mind?

    One moment, you were having a nice picnic with your family—and in the next you're forced into an Encounter and the Monster King's guards kidnap you.

    ...So yeah, definitely not the Sunday you were expecting, but...

    It could be worse, you suppose.

    You could have been kidnapped just for the sole purpose of being forced into a marriage with both of the King's sons.

    ...

    . . .

     

    ...Oh wait.
