    Summary

    After waking up the morning following their late-night pie caper, Kris Dreemurr is surprised to see that the SOUL has mysteriously been broken apart, leaving only a single fragment behind. Not one to look a gift horse in the mouth, Kris decides to make the most out of their newly regained freedom as they return to school, meets up with Susie, and enter the Dark World once more, only to find that they weren't the only human to arrive in Castle Town, as a pair of teenage girls eerily similar to Kris named Frisk and Chara have also come calling from parts unknown, seemingly unable to return to where they came from, and end up joining the Fun Gang as party members.

    With five Legendary Heroes taking up the fight to save the world and prevent the Roaring, all of them able to ACT, FIGHT, and SPARE ontheir own free will, how will this story play out? And what happens when love begins to blossom between Chara and Kris?

    Only one thing is certain: the Prophecy has been utterly shattered, and what comes next is something no one can predict, and mere mortals cannot stop it.

    Summary

    Grillby stood in the remains of an abandoned lab, in flickering dying lighting, flames banishing the shadows that creeped in around him. Clearly, no one had been in this particular part of the labs for some time.

    Grillby wakes up one day suddenly remembering an entire past life- a soulmate and a family that no one knew. And he is going to get him back. No matter what it takes.
    Gaster has almost settled down into this strange new life- trying to understand the Dark World around him and its strange cast of characters.

    Summary

    The first Dark Fountain may have been closed, but the fate of two worlds are now inexplicably tied together. In one, a kingdom prepares for the encroaching storm, seeking to reunite the lighteners with the darkeners so they may hold back the tides that threaten to engulf reality together. In another, two teenagers simply struggle to understand what they mean to one another. Yet, there is no way to escape their fates, so when the time comes, they must be ready to heed the call. The self-proclaimed Angel seeks to shatter the divide; the Heroes shall not let them. This is a story of love and pain, of hate and hope, of imprisonment and freedom.

    This was the second draft of the first story in the “Eden of the Soul” series, “Angels of the Dark,” originally published between October 5th of 2021 and January 13th of 2022. It took place in an alternate universe, and followed Susie after the events of Deltarune’s first chapter as she struggles to understand that she has people who care about her, and won’t let her deal with her problems alone. It suffered from very minimal planning, and with a rewrite officially underway, I came to the decision to move this version into The Vault.

    Summary

    An ongoing collection of Deltarune short stories– Single-chapter one-shots and multi-chapter [Big Shot]s, mainly 'AU's and 'What If's

     

    [EDIT: 5/1/2025]
    Fanfiction is strange.
    It often meets the reader in medias res, assuming the upfront work of having consumed an existing professional work.
    For the big fandoms ingrained into popular consciousness- Spider-Man, The Little Mermaid...- there's a reasonable assumption that most people already know the basics.
    And Undertale has reached that level for a lot of people.

    But Deltarune is its own thing. Its own universe, characters we love just cameos in the background of a new rich story.
    It's like
    An AU fanfiction.

    I'd suggest you play Deltarune. That you give Toby Fox's second major video game production a try, especially if you liked Undertale.

    But if you don't, I just hope you can get something out of this anyway. That it still says something to you through the confusion of learning a brand new strange world without context.

    If you are drowning in the unknown, maybe you can drink some of the water on the way down, and maybe it'll even be sweet.
    Who knows.

    Thank you.

    Summary

    The King of Spades spends more time in his own head than he spends in his own castle, even though the halls have plenty of pretty little plants around now.

    This is part of a larger series of fics, and things might not make complete sense without prior context. I always suggest reading the previous entries first, but there's so many at this point I can't blame you if you choose to just jump in and read this fic without full context.

    Summary

    After the Spades King was overthrown, Rouxls was left without a job. There was already so little he could do, save for be a babysitter for Lancer. He's left bumbling around Card Castle, looking for anything or anyone to give him a job. But most people could hardly stand him, much less have him around for the long hours a job has. One day, he meets someone who could give him the purpose he so desires. But that ends up being more than he bargained for.

    Summary

    Following your monster husband's death and a shortage of teachers at Hometown, you're offered to take up a job as a substitute for secondary, though with the catch of doing more thorough research on the history between humans and monsters as a side quest, continuing where Gerson Boom left off before his passing.

    You prepare a list of potential people who can help you with that research before setting sail, then decide to start with the most easygoing and friendliest monster you believe you can deal with.

    Until he learns you're moving in, and then he stops being so friendly.

    Summary

    Slamming the soul back into their chest is almost as painful as when they ripped it out, but the void in their body fills, and the pain is all but gone. The feeling like they’re missing a vital organ is gone entirely.

    They wait for the control to be taken from them.

     

    It takes them a whole 30 seconds to realize they can still move.

    Summary

    Spade takes Asgore out for "training", and the tides turn unexpected, quickly.

    (This is technically part of the rest of the series its in, but its also kind of its own thing. On account of it being mostly a joke fic.)

    Summary

    Asgore and Spade go to a secluded spot in the scarlet woods to have little picnic date.

    This is part of a larger series of fics - if you want the full context for why this much fluff is necessary, I highly suggest you read the previous entries.

    Summary

    Spade King - along with his son, his co-rulers, and courtiers - was invited to another ostentatious party held for the elite of the Dark World. As his partner, Asgore is coming along for the ride, but somewhere along the way everything gets derailed and it gets harder to tell up from down.

    This fic is a sort-of culmination of everything else in its series that came prior. If you want the full context for the transpiring events, I highly suggest you read the previous entries in "The Spadesgore Collection".

    Summary

    New supplies arrived to the flower shop, yet there's something in the air that seems... ominous.

    Summary

    What's the best way to bond with your son you've drifted apart from in the past couple of years, who's been off to college for so long you've hardly had a chance to talk with him and been out of town so long he hasn't even met your long-term partner? Why, a fishing trip, of course!

    This is part of a larger series of fics - if you want the full context for the transpiring events, I highly suggest you read the previous entries.
