    Summary

    There's only one rule for those capable of AU hopping: never bring a real person into the Undertale multiverse. But, like all rules, it was destined to be broken.

    Summary

    One moment, you’re living a dull life, following the same routine day after day. The next, you wake up trapped in a cold, unfamiliar place, surrounded by bars and creatures that aren’t human. Your purpose here? Maid. At least, that’s what they say. But there’s more to this dark, twisted world than simple tasks. The figures watching you from the shadows have their own plans, and you're nothing more than a pawn in their game.

    is this good enough or what? JUST READ IT ALREADY!

    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

    The RougeRiddler's been named! Also there's a weird hole in the sky again! Finally several new enemies have reared their heads!

    Warning: This Fanfic is not accurate to Undertale canon as the authors didn’t play Undertale when this was written and were 12. This is Book 8 of 9! This is the last complete book in the series! The next book consists of one complete chapter and one uncomplete.

    Summary

    After escaping Nightmare and a tortuously long trial, Killer, Murder, and Horror were released into normal society with no job, connection, or people in this new world. It's okay; as long as they have each other, anything is surmountable, even shitty low-paying jobs or awful roommates.

    As long as they have each other, everything will be okay.

    Summary

    Monsters have been free on the surface for about two months, and Frisk has a problem: They've been having nightmares every day for almost a week, and they’re getting worse. The source of the nightmares? Mount Ebott and a golden necklace they took from it.

    For some reason or another, someone – or something – has latched onto them. Whatever it is, it’s angry, and more unhappy about the arrangement than Frisk could ever know.

    Summary

    Ebott is a corrupt city built on coal, blood, and secrets.

    Years after an incident no one dares to mention, humans and monsters live under an artificial peace sustained by fragile agreements. War is inevitable.

    The question isn't how it will begin.

    It's when.

    As human and monster mafias fight for power in the shadows, buried secrets threaten to rise back to the surface.

    Follow Julia Silevars, a young artist fleeing a suffocating life in search of freedom. When she finds a strange vial containing a substance that should not exist, she becomes the target of dangerous people and is dragged into the heart of Ebott's criminal underworld.

    Save those who still believe in justice?

    Stand against what's coming?

    Or will the cries for help continue to echo for decades more?

    Is your SOUL strong enough?

    Will your Kindness be enough?

    And more importantly...

    Can you convince a certain arrogant, corrupt skeleton to help her?

    I hope you've still got some DETERMINATION left.

    You're going to need it.

    Summary

    Frozen branches and twigs snapped under your thick winter boots. Parts of your jeans would snag on thorn bushes and scratch up your palms as you thwart them away. Heavy breaths of mist puffed out from your dry lips as you dashed through the cold air that crusted over your damp cheeks. The incline of the mountainside had your lungs contracting and sizzling with each greedy gasp you inhaled. Large roots protruded from the heavy layers of iridescent snow, ready to snag your foot.

    As you came to a slight downhill, your body bounded forward until your knees were tucked into your chest as you rolled, arms flailing outwards to grasp onto anything your fingers claimed, but all there was was air. A loud thud rattled your ears, then ringing, and all of a sudden your brain was thumping against your skull, piercing you with tiny needles. Your hand reached up slowly, pulling away warm and slightly red from the collision with the large rock that was currently cushioning the rest of your body.

    Were you going to die here?

    Summary

    After your best skelefriends disappear on you with only a shitty phone-call goodbye for 'closure', you find yourself spending months looking for them everywhere -- failing, failing, failing until one certain trail led you to getting lost in a forest on a mountain, had your life threatened more times than you could remember, and made what were only two skeletons at first suddenly multiply in count.

    What no one expected, however, was how your SOUL made you hold a secret nobody was aware of, and just how it made every single thing connect to you.

    ...Unless, of course, you were Sans.

    Almost unless, anyway.
     
    Just an advice though, dearest Reader?

    Boy, are you in for a ride.
