Nightmare’s gang as a family drabbles by Estel_dreamer
Fandom: His Dark Materials - Philip Pullman, Undertale (Video Game)
16 Sep 2025
Summary
This will be a bunch of one shorts or short stories about Nightmare and his gang being a family. Most will probably be Cross centric cause he’s my absolute favourite. There will be fluff, angst, humour, heartache and much more
Most of these won't necessarily be connected but if they are I'll be sure to specify which ones are

Tasked with the job of protecting his younger counterpart, can Error ensure his ward's safety all while dealing with the threats of the multiverse? Or will he fail and lose Ink to the sea of corruption?
◣•. *࿐✧ ▬▭▬ ✦✧✦ ▬▭▬ ✧☄. *. ⋆◢

Summary
While the characters believe the multiverse has existed for thousands of years already, it truly starts with the first sentence of its story. Only Ink feels when it happens.
(...And then panics because he's now aware he's never actually protected a universe or had a conversation with a friend and probably doesn't know how to do any of that and they're all counting on him.)

Summary
This fic is more of a what if situation. What if instead of Nightmare taking Cross in, Error ended up doing that? How different would things be?
----
Error watches, unflinching, as the skeleton's giant knife materializes, slicing through the stillness of the void. The vibrant glitches around his fingers pulsate more vividly in response, mirroring the tension. Despite the display of power, Error’s demeanor remains composed, almost amused by the dramatic reaction.
"You can call me Error. As for how I arrived here," he gestures loosely around them with a hand threaded with glitches, "I travel where the code calls, where anomalies beckon. Where the multiverse needs cleaned of anything that could harm it, and this place," he pauses, glancing around the stark whiteness, much like his own home, "Screamed for attention."
His gaze settles back on Cross, the colorful chaos of his form stark against the void. "You, however, are an interesting anomaly. Fighting so fiercely, clinging to existence in a world that has seemingly been erased." Error hummed, eyes still searching.

Summary
He raised his head with difficulty. His eyes widened in surprise. In front of him was a portal, as glitchy as he himself, and he could see a dark sky with stars.
Error extended his hand and it easily passed through the portal and on the other side a light breeze blew across his fingers. It seemed that strength suddenly filled his body, and the magic responded with warmth and he literally jumped into the portal, turning out to be on an island that flew among the stars.
A surprised sigh escaped him before he sank down again, but now it was no longer the white empty floor of void, but I was soft, cool grass.
Stars, how he loves it here. This place is much better than anti-void.

Summary
Create-Tale, an unknown location between the empty space of the multiverse that separates the bubble of sketches from the antivoid. Who would have thought that the locals of both places would be in charge of the most important possession in the multiverse?
The world of the creators, powerful souls who follow these guardians and worship them as warriors. However, that security would fall behind human curiosity. After all, they are not fictional, like the creations. Or rather, their creations.(This story contains sensitive content; it is primarily intended as a horror story.)
(and yeah, errorink is canon here, guys /jk)

Summary
Nightmare has grown weary of the constant strife between himself and his brother. Every time he manages to fuel the ever-persistent need for negativity in his system, Dream and his friends immediately sap it out of him.
So, Nightmare has decided he was done. If they believed the multiverse was better without negativity, he was okay with that. He'd well descended past apathy years ago.

The Human just couldn't help themselves. This run was clearly different from all of the others if that strange encounter was anything to go by, could you really blame them for getting curious?
This is something they will most definitely not regret.

Summary
It started out as a joke with Killer asking Nightmare who his favourite kid was. The King of Negativity gave the generic parent answer of not having a favourite while Error had no problem in saying his. They had laughed it off, thinking it a joke. It’s not till the Stars make the biggest mistake in their lives that they realise just how serious Error actually was.

[formerly aoam: extras
but i only ever posted this oneshot and have since realized a "non-canon extras collection fic" is not a very good way to organize this. so from now on, other oneshots will be posted as oneshots. the content of this fic has not changed.][characterization is from my other fic, awakening of a multiverse. not canon, mostly just because it doesnt fit into the story anywhere.]
Error finds Ink, trapped in the Anti-Void, and rescues them.

That Time Blue Boned The Destroyer of Worlds by Mochimunchies
Fandom: Undertale (Video Game)
22 Dec 2024
Summary
Blue thought he had a pretty magnificent life. He had the bestest ever friends in Dream and Ink (even if the two sometimes still needed some guidance as to how living with mortals work), an amazing brother who he loved and respected very much (even when Honey could still be silly about a few things), and best of all, a datemate whom he loved very, very, very much..! Even if they had to be discreet about their relationship.
At least, until one night of passion and poorly managed intent had left them with something that they couldn't be discreet with.
As he prepares to take responsibility for his actions and dedicate himself to a domestic life with his beloved mate-to-be, Blue is faced with only one question:
How does he break it to his friends and family that he knocked up the Destroyer of Worlds?

Summary
It’s been 494 years since Nightmare turned Dream into stone. Nightmare wakes up in the middle of the night to a sudden surge in positivity, realizing who it likely is, he decides to teleport straight to the source.
He finds his brother, but he hasn’t aged a day. Nightmare stares at the 6-year-old, actually seeing Dream makes him fully understand just how young both of them were at the time. He realizes neither of them was truly at fault for what happened, they were both just kids who needed someone to parent them.
This realization causes Nightmare to take Dream in, becoming the responsible adult they both needed.

Summary
"There's only two things in this world you can be, the one that perseveres, or the one whose body is left for the beasts." The stable hand stated weakly.
Ink curled up beside him and tried to ignore the sounds outside his little sanctuary, the rattling of his shaking bones doing little to cover them. He picked at the spaces between his phalanges and stared unseeingly into the stalls across from them. Perseverance? The concept felt so foreign to his young and shaken mind.
How could he possibly persevere when it felt as if he was unraveling?
(A swap au of my dear friends' multi-chapter fic, Perseverance. Detailing a scenario where Asgore had not found Ink on that last search party, and Ink was forced to survive outside the kingdom walls. You do not have to read Perseverance to enjoy this fic.)
