Tributary: A Deltarune Fanfic Collection by Boh_No, DE__EMBER (Boh_No) for BloomingMiracle (Luna264)

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.

Whatever Remains of December Holiday by TransgenDeer1225
Fandoms: Deltarune (Video Game)
05 Oct 2025
Tags
Summary
Noelle Holiday is older than her sister was, when she went missing. She would lie to herself and claim that she has healed, but everything still reminds her of what she has lost. She has refused to let anyone into her heart since then, missing the sibling who she told everything, and the friend who allowed her to be herself.
Kris Dreemurr is drowning in a conspiracy that is threatening to unravel the whole world. They promised to find her again, after she was lost - and only Kris recognizes that they have. Only now can they begin to dream of the forgotten past, and a future where everyone lives.
December Holiday went missing seven years ago. The attempt to bring Her back failed, and now it lives instead. It is not Her, it cannot be the girl that was lost. The pieces of Her comprise its mangled form, to form a corpse from a species that never leaves behind a body. It is merely Her Remains.
Berdly has no idea what he's done to get involved in this mess.

Summary
Unwillingly, Kris looks up and begin to examine the rest of Susie, noticing features more easily now. The slight rise and fall of her chest underneath the white t-shirt, the way some of the moon’s light reflects off of her scales, how a few of those scales on her cheeks are darker in color, like freckles. There’s an amount of worry in her expression which hits their heart in a way Kris never expected it to.
But standing out from everything else, it’s that her eyes are so… gentle. Susie’s bangs are brushed aside, bright yellow scleras that seem to glow in the dark with pitch black pupils looking right back at them. Her gaze on them feels warm.
Oh. Oh no.
You fucking moron. You can't be falling for her.

Eden of the Soul, Volume One: Angels of the Dark (2021-2022 Version) by AnomNom
Fandoms: Deltarune (Video Game)

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
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.
