A Quiet Indulgence

Asirel Cain x Pet

The estate was pristine, quiet, and meticulously curated, just as Asirel liked it. Everything had its place—every marble tile, every glass of fine wine, every piece of furniture. Even Pet had a designated place in it, though their presence was often less visible, more subtle. Tonight, however, Asirel noticed the quietness in the air. A silence that spoke volumes.

Pet had returned.

The door opened, and Asirel didn’t need to look up. He could feel their presence, the slight shift in the atmosphere that told him they were standing there, waiting for him to acknowledge them. A quick glance over his shoulder confirmed it: Pet was standing in the doorway, hands clasped behind their back, posture stiff yet expectant.

“Late again?” Asirel’s voice was smooth, amused, though the playful glint in his eyes betrayed the amusement he found in the situation.

“Forgive me, Master,” Pet said softly, lowering their head.

Asirel didn’t respond immediately, letting the moment stretch as he continued to look at the papers in front of him. Then, with deliberate slowness, he set them aside and turned his full attention to Pet. “You do know I don’t appreciate being kept waiting,” he said, his tone teasing yet firm. “Tell me, did you manage to find some new and inventive way to make trouble tonight?”

“No, Master,” Pet replied quickly, their voice tinged with a faint nervousness. “Everything went as planned.”

“Hmm.” Asirel leaned back in his chair, studying them with that calculating gaze that always seemed to see right through them. “And yet, here you stand, looking like you’ve barely survived the day. Should I be concerned?”

“I’m fine, Master,” Pet insisted, though their voice lacked its usual strength.

“Are you?” he murmured, tilting his head slightly. His lips curved into a small, knowing smile. “You don’t sound fine. Come closer.”

Pet hesitated for a fraction of a second before stepping forward. Asirel’s gaze swept over them, taking in the slight tension in their shoulders, the way they avoided meeting his eyes. It was subtle, but he knew them too well to miss it.

“You’ve been working hard for me,” he said, his tone softening just slightly. “And yet, you look as though the weight of the world has been on your shoulders. Tell me, Pet—” He leaned forward, his voice dropping to a low murmur. “Have you been neglecting yourself again?”

Pet shifted under his gaze, their fingers tightening around the edge of their sleeve. “I only do what you ask of me, Master.”

Asirel chuckled, the sound low and amused. “A clever answer, as always. But I’m not convinced.” He stood slowly, moving around the desk with the grace of someone who always had complete control of his surroundings. “Come now, don’t look so forlorn. You’re too valuable to me to be falling apart.”

Pet finally lifted their gaze, meeting his eyes for just a moment before lowering their head again. “I’m sorry, Master.”

“Hmm.” Asirel came to a stop in front of them, his expression softening, though his tone remained teasing. “Apologies won’t do. You’ve done your job. You’ve earned a little indulgence tonight.” He reached out, his fingers brushing lightly against their chin, tilting their head up so they had no choice but to meet his gaze. “But only because I’m feeling generous.”

“Thank you, Master,” Pet murmured, their voice barely above a whisper.

“You’re quite welcome.” He stepped back, gesturing toward the armchair near the fireplace. “Sit. Relax. I’m not cruel enough to keep you on your feet after such a long day.”

Pet moved to obey, sinking into the chair with a quiet sigh. Asirel retrieved a glass of water from the desk, placing it in their hands before settling into the chair opposite them. His sharp eyes never left them, watching the way they held the glass, the slight tremor in their fingers.

“You know,” he said after a moment, his tone light, almost conversational, “I sometimes wonder if you forget you’re mine. You push yourself so hard, and for what? To impress me?” He smirked. “You already have my attention, Pet. There’s no need to work yourself into the ground.”

Pet’s grip on the glass tightened slightly. “I only want to do what’s expected of me, Master.”

“And you do,” he replied smoothly. “But even I can tell when you need a moment to breathe. So take it. Just this once.” He leaned back in his chair, his smile softening into something almost fond. “I can’t have you breaking down on me. Who else would I play with, and give attention too?”

Pet looked down at the glass in their hands, a faint hint of a smile playing at the corners of their lips. “Yes, Master.”

“Good pet.” Asirel’s voice was low, almost a purr. “Now, enjoy this little reprieve while you can. Tomorrow, you’ll have plenty of chances to prove your loyalty again.” He reached out, brushing his fingers lightly against their hand. “But for now, you’re here. With me. And that’s all I require.”

Pet’s shoulders relaxed, the tension from the day slowly melting away under his gaze. They weren’t free—not by any means—but in moments like this, when Asirel’s attention was fully on them, it was easy to forget the confines of their world.

And for tonight, that was enough.

An Unexpected Surprise

X Men Masterlist

X Men Masterlist 2

Y/N stands in her small room, gently rocking Lyall in her arms. The wind howls outside as rain lashes against the windows. The little boy sleeps peacefully, his breathing steady, while Arktis, Y/N’s white wolf dæmon, lies silently on the floor, keeping watch. Almost a year had passed since Lord Asriel had left her, unaware that she was pregnant. Now, he was on his way back. Y/N had received the letter announcing his return, and her heart had been restless ever since.

“Will he understand?” Y/N whispers, more to herself than to Arktis.

The wolf lifts his head, fixing her with his clear, silver eyes. “He will have to,” Arktis says calmly. “But he will be angry. Be prepared.”

Y/N sighs. She knows it won’t be an easy meeting. Asriel, the strong, proud man who was always off fighting great battles and dangerous missions, had no idea about his son. The months of silence had tormented her, but she had no way to reach him. And now that he’s coming, she’s afraid. How will he react? What if he doesn’t understand? What if he judges her?

Then she hears footsteps. Heavy, determined footsteps approaching. Her heart skips a beat. It’s Asriel. He’s here.

The door opens, and Asriel steps in. He looks unchanged, still as imposing and strong as she remembers. But his eyes are different—harder, colder. Behind him, Stelmaria, his proud snow leopard dæmon, glides silently into the room.

“Y/N,” Asriel says in his deep voice. His gaze falls on her, then on the bundle in her arms. For a moment, there’s a heavy silence in the room, as if even the air is holding its breath.

Y/N stands still, clutching the sleeping child to her chest. She wants to speak, to explain everything, but the words get stuck in her throat. Arktis rises slowly, positioning himself protectively beside her, his eyes locked on Asriel.

Asriel’s eyes narrow as he looks at the child. “What is that?” he asks sharply, suspicion lacing his voice. “Whose child is that?”

Y/N flinches at the coldness in his tone. “It’s... our son, Asriel,” she whispers at last.

For a moment, time seems to freeze. Asriel blinks as if he doesn’t understand the words. Then he steps closer, his expression hardening. “Our son?” he repeats, disbelief and anger evident in his voice. “Are you telling me this is my child, after all this time? I’ve been gone for almost a year, Y/N. And now you suddenly present me with a baby?” His voice rises, growing sharper. “Have you betrayed me?”

Y/N steps back, her face pale with shock. “No, Asriel, I swear to you, I haven’t betrayed you!” Her voice cracks, but she fights back the tears. “Lyall is your son. I didn’t find out until after you left. I had no way to tell you I was pregnant!”

But Asriel isn’t convinced. He takes another step toward her, his eyes flashing with anger. “So that’s your excuse? I’m gone, and suddenly there’s a child?”

Sensing the rising tension, Arktis steps closer to Y/N and the baby, his fur bristling slightly, a low growl rumbling from his throat. “This is not the time for your anger, Asriel,” the wolf warns, his voice calm but threatening. “She has told you the truth.”

But Asriel is too furious to listen. “Stay out of this, Arktis!” His voice is sharp, but before he can step any closer, Stelmaria rises. She moves between him and Y/N, her fur shimmering in the dim light of the room. A growl escapes her throat, and her sharp eyes glint at him.

“Asriel,” Stelmaria says with a calmness that contrasts starkly with his rage, “look at the child.”

Asriel pauses, his eyes locked on the snow leopard. “What?”

“Look closely,” Stelmaria repeats softly but firmly. She steps closer to Lyall, who now stirs slightly in Y/N’s arms, his eyes fluttering open. “The child has your eyes, Asriel. Look at him. He is your son.”

Reluctantly, Asriel’s gaze shifts to the boy. At first, he sees only the small, peaceful face, but as he looks closer, he recognizes it. The child’s face bears traces of his own features—the shape of the eyes, the line of the chin. It’s unmistakable. The anger inside him begins to fade as the weight of the truth settles on him.

“That... that’s impossible,” Asriel murmurs, his voice suddenly fragile. “He... he looks like me.”

Y/N looks at him, tears now streaming down her cheeks. “I told you the truth,” she whispers, her voice full of pain. “Lyall is your son. I wanted to tell you, but you were gone, and I had no way to reach you.”

Stelmaria moves quietly to Asriel’s side, her eyes softer now but still vigilant. “There’s no doubt, Asriel,” she says gently. “This is your child.”

Asriel stands motionless, the weight of the realization pressing down on him. His eyes drift back to Y/N, who meets his gaze with a wounded but determined expression. The mistrust that had plagued him for so long begins to crumble.

Asriel lowers his gaze, his anger completely gone. He knows she’s telling the truth. A heavy sigh escapes him, and he suddenly feels exhausted. “I should have been here,” he murmurs. “I should have been with you.”

“But you’re here now,” Y/N says softly. “And that’s all that matters.”

Slowly, Asriel steps closer to her, his hand reaching out as if he’s seeing the child for the first time. As he gently places his hand on Lyall’s tiny head, he feels an unexpected warmth spread through his chest. The realization that he is a father overwhelms him.

“I’m here,” he says at last, his voice firm but gentle. “And I won’t leave again.”

Asirel x Pet || Angst/comfort

3rd person and she/her pronouns

Masterlist here

~~~~~~~~~~~~~

The room was cold as Pet sat on the sofa, awaiting the return of Asirel. He had been especially busy lately and only come to see her three times in the past week.

Pets ears prick and she turns her head as the door creaks open, she had heard his footsteps coming down the hall but time and time again he had just walked past, ignoring the festering annoyance and anger in her demeanour.

Asirel set down some files onto his desk and shuffles them into separate piles, being as picky with his ordering as usual, and moves to stand next to Pet, watching her closely as she turns her head away from him sharply.

“Whats wrong, Pet?” Asirel finally asks and Pet huffs, standing and moving over to the fireplace, placing kindling down and lighting the fire-lighter beneath them, attempting to warm the room up. It would be uncomfortable to try and sleep in a room as cold as this, of course a vampire would have no issue but…

“Talk to me, whats on your mind?” Asirels smooth tone makes Pet pause, taking a deep breath and watching the gentle flames wrap around the wood.

“You’ve been out a lot lately, and im hungry,” Pet finally mumbles, just loud enough for Asirel to hear and she continues to slowly stoke the fire.

“You know that work has been stressful lately,” Asirel perches himself on the armchair a few feet behind Pet, “especially with the recent death, his funeral was two days ago so im still going through paperwork for his coworkers to have.”

Pet stays silent for a moment, her frown deepening as she places a small log onto the fire, the dry wood catching quickly and the heat steadily rising, “you said id get attention and feeding, in return id protect you. I have not been needed, nor have i been fed. Im a wrestles person you know, Asriel,” Pet says lowly, her anger spiking, matching the flickering flames before her.

Asirel sighs as he stands again, sauntering over to stand behind Pet, “there are plenty of people here you can feed from, i told you that we have people being held especially for you, you just have to ask.” He crouches down and pulls back Pets hair, brushing through it gently with his fingers.

“I dont want to feed from them, i want you!” Pets voice rises as she shakes her head and turns to face him.

“Pet, im busy but i can give you attention now, i have a meeting early tomorrow though so i wont be i for most of the day,” he attempts to compromise but Pets hostility seems to grow even more.

“Exactly! You say you want me to intimidate people or whatever but you never take me anywhere! You keep me in this room, alone and hungry, but that’s not fair!” Pets anger mirrors the angry flames behind her, she balls her hands into fists and leans forward towards Asirel.

“I should just do what i did before! I should take what i want and drain you because you dont care! You never did!” Pet lunges at Asirel and his eyes widen, attempting to pull away and stand up but Pet was too quick, “i hate you! I hate all of you! You’re a liar!”

Pet keeps Asirel beneath her as she screams, her eyes welling with tears as she stares down at Asirel, his fear slowly starts to shift into understanding and maybe even sympathy as he stares up at Pet.

“I cant believe i thought you’d be any different! I should kill you! It’s what i want! It’s what I’ve wanted since the moment i was out of those fucking chains!”

Asirel brings an hand up to Pets face, his gaze meeting hers, “i can tell you’re not an angry person, i can see the sadness in your eyes.”

His words were soft and Pets breath catches, they hold eye contact before Pets face starts to crumple, finally letting their body go limp as Asirel sits up, pulling her body into his. She sobs into his chest as he rocks her gently and goes back to toying with her hair.

“Its alright, you’ll be okay. I know i haven’t been around much, youre right, you should be able to come with me to work meetings. Its why i originally wanted you, but i was worried that you would find it overwhelming, i thought you preferred to stay here where its quiet and peaceful. I was wrong, and im so sorry.”

Pet looks up, meeting his gaze as he wipes away a tear from her cheek, “i hate being alone.”

Asirel cups her cheek in his palm, keeping her grounded and focused on him, “then i’ll never leave you again.”

[mlmvoreconfessionals]

ooh, how about some prompts for an extremely flustered Asriel getting relentlessly teased by preds who found out he's into vore? (Asgore, Rudy, and Sans would be nice, but whoever honestly)

Oh I'd looove to do this.

“C’mon, A.zzy, there’s no shame in snuggling with your old man, is there?” A.sgore asks with a big smile. He’s got a large arm around A.sriel, and the smaller goat is blushing hotly as he’s being squeezed against his father’s gut. The organ lets out a deep, wet groaning noise and sloshes around weakly as someone moves inside.

“Did you…have to eat my boyfriend, though?” A.sriel asks, unable to keep his eyes off his father’s gut. He’d brought his boyfriend over specifically to meet his dad. He thought things were going well but…A.sgore had just casually opened wide and scarfed A.sriel’s boyfriend down right before snuggling.

A wet burp escapes the older goat and he pats his gut a few times. “I’m just snuggling him, too! Makes sure there’s plenty of room on the couch.” A.sgore chuckles softly and slurps over his lips.

“I guess, but…” A.sriel trails off for a second as he feels A.sgore’s guts gurgle deeply against him. He can hear some muffled yelling inside, and he knows that his boyfriend isn’t having a good time. “…I think you’re digesting him, Dad.”

“Aw, I’m sure it’s not that bad,” A.sgore reassures with a smile. “Your boyfriend can handle being in the belly of an old man like me for a little while, can’t he?” ‘Old man’ is what A.sriel’s boyfriend had called A.sgore before he…

Another deep rumble comes from A.sgore’s gut, which A.sriel is starting to gently rub. “I…guess so, yeah.” He knows that his boyfriend probably isn’t coming out any time soon. Or at all. But this is…kind of nice.

“Besides, you enjoy this kind of stuff, right?” A.sgore goes on. “I saw you looking at this kinda stuff on your phone the last time you visited. So it’s working out for everyone, right?”

A.sriel’s face turns even redder. His dad saw that?! He buried his face in A.sgore’s stomach with an embarrassed whine, but his hand is still rubbing over the goat’s gut. “Dad, that’s sooo embarrassing..!”

A.sgore chuckles softly, but it’s interrupted by another wet belch as his guts gurgle thickly. A.sriel’s boyfriend is starting to move a lot less, the gut getting softer. “Golly, sorry, A.sriel. I thought you’d like this!”

“…I didn’t say I don’t…” A.sriel mumbles a bit into his dad’s stomach. He can feel the moment his boyfriend stops moving and A.sgore’s stomach starts to really work on him. “…I’ll make sure I have another boyfriend next time I visit. If you want.”

A.sgore blinks, then smiles softly. He gently rubs over A.sriel’s back as he feels his son snuggle into his gut. “That sounds like fun, A.zzy.” He sits back and lets out a final, deep belch, followed by a content sigh.

---

“R-R.udy?” A.sriel’s face turns red as he walks into his room at his dad’s house, just to find the reindeer relaxing on his bed. But more than that, he’s also sporting a very...large stomach. It’s gurgling and rumbling heavily, stomach shifting around inside.

“There ya are, kiddo!” R.udy flashes his usual big, toothy grin. He had his arms folded behind his head at first, but now he gives his stomach a few pats. “I was worried you wouldn’t get back in time! This old thing still works like a charm.” R.udy’s stomach lets out a deep, wet groan, whoever was inside shuddering and making the gut shift.

“What are you...doing in my room?” A.sriel starts moving closer, eyes on the reindeer’s stretched gut. He finds himself sitting on the bed, and without really thinking, he puts a hand against the gut. He can feel it burble deeply, and whatever was inside pushes back weakly. There’s a bit of give to the mass. A.sriel can tell that whoever this is has been digesting well.

“Fluffybuns only has the one guest room,” R.udy comments, slurping over his lips. “Just so happened I heard you were visiting while I was over! You don’t mind sharing the room, do ya? I bet I can make the three of us fit juuust fine.” R.udy pushes his hands down into his stomach, working out a thick, wet belch.

“I uh...I mean...I guess...that’s fine...” A.sriel gulps softly, starting to rub a bit deeper into R.udy’s stomach. He can feel how hard it’s working, melting down whoever it was the reindeer ate. The prey is starting to move less and get softer.

“I knew you wouldn’t mind,” R.udy says with a snicker. “Your old man mentioned this was a good way to get you to come around. And I gotta agree!”

A.sriel lets out a little huff, feeling embarrassed. “Ugh, Dad, does he really have to go around telling everyone..?”

“Don’t worry, kiddo. I don’t think he’s going to be telling anyone anything for a while.” R.udy grins when A.sriel looks up at him in confusion. The mass in his stomach goes still with a final shudder. R.udy leans forward, squishing his gut against A.sriel, and lets loose a deep, thick belch in the goat’s face.

A.sriel doesn’t pull away, his entire face going red as he stares into the reindeer’s maw and gets a good whiff of gut stink. But something comes up as R.udy’s guts soften and churn. Soft tufts of white fur, a bit of it getting stuck to A.sriel’s nose. The goat blinks and crosses his eyes to look at it. “...huh? Isn’t that..?”

R.udy chuckles and slowly slurps over his lips. He leans forward more, until his large gut is bowling over A.sriel and forcing the goat down under him. He sighs contently and relaxes on top of his groaning, gurgling stomach. “I think...the two of us are going to get along just fine, kid. And you can thank Fluffybuns for that one~”

---

A soft, embarrassed whine escapes A.sriel as the glowing blue stomach presses up against him. He was just trying to get a bit of shopping down at the new grocery store in town, and the skeleton, S.ans, had offered to help him ‘look around’. This is the fifth time he’s felt that gut press against him while S.ans tried to ‘show him’ where something is on a shelf.

Even worse, someone’s moving around in there. S.ans had eaten someone who had gotten annoyed over the skeleton abandoning their checkout halfway through to help A.sriel. They’re still kicking around in there, the blue gut hanging down to S.ans’s ankles. S.ans is shorter than A.sriel, but right now, he’s got weight to use. And he keeps using it.

A.sriel lets out a soft sigh when S.ans finally backs off on him, the skeleton’s gut sloshing and bouncing a bit as the person inside is given their space back. The random, unfortunate customers are still moving around in there but it’s slowed. Being squished over and over has been wearing them down.

“Well, I think that’s the end of the tour,” S.ans says. “But I still got something in store for you, kiddo.”

A.sriel can’t stop himself from snorting into his hand. He doesn’t want to laugh over such a bad joke, but they always get him. He clears his throat and tries to recover. “Uh...wh-what do you mean?”

“Still got the back.” S.ans turns and waddles off, his gut sloshing with every step. He heads behind the counter again and A.sriel follows along, watching the stomach the whole time. Once he’s behind the counter, S.ans makes him sit on the floor, back up against the counter. The goat is confused at first, but then he gets what S.ans wants.

S.ans’s stomach squishes against A.sriel, resting in his lap now and pressed against his body. His nose pokes into the soft blue gut a bit. Like this, he’s completely pinned down, forced to stay in place while the gut works. S.ans leans on the counter, resting his head in his hand. A wet belch rumbles out of him, followed by a content sigh. “I needed a cushion for the tank. I heard goat fur is the softest. What do you think?”

A.sriel lets out a soft bleat as S.ans grinds his stomach into him a bit. The whole thing gurgles and groans deeply. The customer inside is mostly still now, other than some occasional twitching. The organ keeps letting out harsh, wet noises as it works. With nothing else to do, A.sriel presses his muzzle a bit further into the gut. “Uh...y-yeah, something like that.”

“Good to know,” S.ans says. “I’ll just pretend I don’t feel anything hard down there, then.” Another bleat from A.sriel gets him chuckling softly. “Dunno how long you plan on staying in town, kiddo. But if you’re looking for something to do, I can hire you. Part-time gut cushion. How’s that sound?”

The stomach rumbles thickly against A.sriel. He can feel the person inside go fully still. He has just enough movement for his arms to rub his paws into the softening mass a bit. “...sounds...great.”

“Heh. Then you’re hired.” S.ans belches wetly again as he feels A.sriel bury his face into his stomach. “Have fun down there, kiddo.”

[a-legacy-not-to-be-forgotten]

Undertale Yellow AU idea: SequenceShift

Since my boyfriend @cent-the-proto and I still have severe Undertale Yellow brainrot, we decided to make an AU together. The main concept is UTY characters taking the places of OG Undertale ones, and mashing plot beats from both stories together with some new locations (which are a hybrid of Japanese and Western inspiration).

While this is a 'shift' AU, I'm keeping the personalities of the characters intact rather than swapping both character placements AND personalities. It's what I found frustrating about most Shift AUs: changing the personalities just defeats the point of the AU in the first place imo. I'll be honest, I haven't looked into many other AUs, so if our concept is too similar to someone else's, please let me know. Also, we only figured out the characters and setting, so any suggestions are welcome! (comments or ask box) . Also, should go without warning, this has spoilers for both Undertale and Undertale Yellow, so read at your own risk. Again, not an artist, so I don't have any drawings yet.

Also, quick shoutout to @s0ckh3adstudios and their Undertale Gold AU for inspiring me to make my own.

With that out of the way, let's get into the core characters of SequenceShift! (title is a placeholder, unless I can't think of anything else)

Clover, The Fallen Human

Gunhat Clover is largely unchanged from their cannon standpoint. Cowboy-themed human, fall down to the Underground intentionally to search for the six fallen humans (yes, six, they're taking Frisk's place), embodiment of justice and all that. Not much else to say, so let's move onto the big changes.

Kanako Ketsukane, The Crown Princess

Kanako takes the place of Asriel/Flowey. Daughter of Empress Ceroba and Prince-Consort Chujin, before having passed away years ago in what has only been publicly stated as 'natural causes'. She's also reincarnated as Flowey (who might or might not get a name change), but she takes the form of a Japanese Water Iris this time around. She also acts as the SAVE function like Flowey in OG UTY, keeps up the friendly facade all the way through, and insists on calling Clover Gunhat despite knowing their actual name.

Ceroba Ketsukane, Empress of the Underground

Ceroba is the Asgore of the AU (originally it was going to be Toriel, but I thought it'd be more interesting). She is the Empress of the Underground, generally seen as a level-headed, yet passionate monarch. However, following her daughter's demise, she has grown a bit of a more bitter streak, and like Asgore is focusing on collecting the souls of fallen humans. Unlike Asgore, she doesn't hold malice for mankind as a whole nor is she interested on waging war on the surface. Instead, she merely collects the souls of humans in the hopes of resurrecting Kanako. Also, both she and Chujin are boss monsters in this AU.

Chujin Ketsukane, the Prince-in-Exile

Chujin takes the place of both Toriel (with a bit of Gaster) in SequenceShift. Originally, he was the Royal Scientist, who's kind nature and ingenuity caught the attention of then-Princess Ceroba, who he eventually married. They lived happily at first, but things took a turn for the worst after Kanako's death. Ceroba's obsessiveness with collecting human souls displeased him and he refused to take part in the experiments. He's since gone into self-exile within the Remnants (aka the Ruins but with a more Japanese architectural influence) and has settled within Ceroba's childhood home. Here, he keeps a watchful eye for any humans who fall to the Underground, hoping to keep them away from the Empress's grasp.

Dalv, the Introvert

Dalv takes the place of Nabstablook. As much of a socially awkward looser (affectionate) as ever, and corn obsessed. Like the OG, he was friends with Kanako before her death, tho I'm not sure if I'm keeping him being a victim of Integrity's bs. Unlike the OG, he's not restricted entirely to the Remnants and actually has a place within the Dunes. He also has a bit of a secret crush on the leader of the Royal Ranger Starlo, just to satisfy you Corn Yaoi lovers.

Moray and Mooch, Ranger Sentries

Moray and Mooch take the place of Sans and Papyrus, respectively. They act as sentries of the Royal Rangers (the Feisty Five taking the place of the Royal Guard), who are responsible for apprehending humans and bringing them to Ceroba. Mooch is as mischievous as ever, still trying to get her hands on every shiny object she sees, much to her partner's dismay. Nevertheless, they remain vigilant at watching over any humans that emerge from the Remnants. In this AU, they're responsible for surveying the region of Lakeside, which is modeled off of the rural Japanese countryside, and takes Snowdin's place.

North Star/Starlo, Sheriff of the Royal Rangers

Starlo is obviously the Undyne of the AU, being the leader of the Royal Rangers. A lot of his backstory is the same, him crushing on Ceroba and sadly not getting her, but still remaining good friends, even after she was made Empress. He and the Feisty Five started in the Sand Dunes (aka just the Dunes from UTY with a bit of Waterfall inspiration) similar to how they were in the original, before Ceroba elevated them to being her personal enforcers. He's still pretty self-centered and idealizes Western culture (hence why he still refers to himself as Sheriff), but he does have a more serious and dedicated side to him. He knows what he's doing is wrong and while he hides it, he's fairly reluctant to bring more humans to Ceroba. Nevertheless, he still carries out his orders in the hopes of making his childhood friend happy. One fun fact, we had the idea for his pacifist encounter taking you to Frostpeak (a MT. Fuji inspired area taking the place of Hotland), where the chase there leads to him freezing, kinda like how Undyne overheats. Bro is not built for the cold.

Martlet, the Royal Scientist

Martlet, surprisingly enough, takes the place of Alphys. Like in UTY, she started as the protégé of Chujin, helping him out with the Steamworks and in building Axis. However, after Chujin fled, Ceroba made her the next Royal Scientist. She works at the Steamworks, which take the place of the Core and instead located in Frostpeak, where it harvests Geothermal energy to power the Underground. While Martlet actually is pretty competent at her job, she's as scatterbrained as ever, leading to a few hiccups in her work and leading some to wonder why she's the head scientist. This is actually due to the fact that she has been tasked by Ceroba to continue Chujin's work on humans. She's complied so far, for now, but she might reach a breaking point soon enough...

And that's the main cast so far! Axis and Dalv still being worked around with and I gotta think up ideas for the side characters along with whatever the OG cast of Undertale is up to, but we got a good thing going on. Again, my comments and ask box are always open, so if you're wanna know more or have a suggestion to bring forth, we'd love to hear. And if my AU is too similar to a concept that's already been done, you're more than welcome to yell at me.

[stainedglassthreads]

In early fandom days, there were. So many Save Asriel AUs. A few of which, (presuming I remember correctly), feature Frisk going on a No Mercy Run either because they got bored trying to save Asriel, or because... they thought it would let them save him in some way...? (Never made sense to me, I don’t know.)

Anyways I should write a fanfic where Asriel initially shifts his idolization tendencies from Chara to Frisk, because Frisk has been so kind and compassionate towards him, more forgiving than he ever deserves. And then Frisk somehow presents him with enough souls to regain his goat form so he can have his happy ending too.

And then Asriel just realizes.

Wait.

How many True Pacifist runs have they reset?

How many times have I asked them to reset my memory, too?

How long did they spend determining this? What did they do to achieve those souls?

Are they just... the same brand of completionism as me and Chara?

And then he has to grapple with his tendency to idolize people and the dawning realization that Frisk Is Actually Kinda Weird And Maybe Also Has Their Own Issues And Obsessions. And isn’t necessarily better or worse than either him or Chara: merely different.

[grimxrcxper]

Asriel leaned back in his chair, the worn leather creaking softly under his weight. His piercing blue eyes fixed on the person before him, a flicker of amusement dancing just beneath their intensity. He steepled his fingers, his expression calm, calculated—though inside, a ripple of irritation stirred at their naivety. ❝I didn’t deceive you,❞ he began, his voice smooth yet laced with a faint edge of condescension. ❝I curated the narrative to align with what you were prepared to hear.❞

He paused, watching their reaction, noting every twitch of discomfort, every flicker of doubt. It was almost satisfying. Almost. ❝Truth, after all, is a matter of perspective,❞ he continued, leaning forward now, his tone shifting to one of quiet intensity. ❝It’s shaped as much by what we leave unsaid as by what we reveal. If you wanted the full picture, perhaps you should have asked the right questions.❞ Inwardly, Asriel wondered how they could be so blind, so predictable. They had walked straight into his carefully constructed web of half-truths, and now they were floundering, grasping for clarity where none existed. Humans, he thought, were endlessly fascinating in their ability to overlook the obvious

"Perhaps if I gave a damn about what you were talking about human then I would have asked the right questions but you aren't the only one that's been keeping secrets." Steff looks at him as he let's his human face melt into that of a skull "You've been trying to fuck with Death little one and that isn't very nice of you now is it? I wonder if you would have given me the answers if you knew exactly who and what you were dealing with." He walks across the room his frame expanding and the flesh fading from his bones "I know where's the cape and the scythe right? Sometimes I just don't even bother calling them when I need to make a point. You don't lie to Death you little shit."

He turns back into his Earthly form and sits down on the other side of the desk from Asriel "Alright, I'll bite. What was I supposed to be ready to hear or should I say not ready to hear. There has to be more than you're telling me still but I can't say that the life of humans is all that interesting to me when I'm the one that takes it away." Steff then reclines in the chair and looks at the ceiling "But I absolutely hate it when someone takes the choice of what I should and shouldn't into their own hands. If I did that I would be called more of a monster than I already am." He chuckles then and cocks an eyebrow at the other "You really need to do your homework on who you let into your lab doctor or who knows what kind of supernatural thing might end up in here."

@asrielbelacquaaaa

[justanechoflower]

She chuckles. "Can't take back a fact."

She shifts on top of him. "Do anything funny and I will tickle you until you pee." She threatens with a playful stare before standing upright, letting Flowey free. That was an empty threat.

"The question is, if you'd allow, can I be your unofficial sibling? You got Grauntie and Faysal as your unofficial parents." She asks him, curious.

The kids I thought I had were just my younger siblings that I had to take care of.

Used to be friends with Bill but the bill in the system is not the same one.

Bill erased my memories of my younger siblings after the fire so we got into a bad fight.

Hi sleepy! Can I get some birthday related fics?

Today is my birthday! And I am still a minor!

Also, how are you today, I hope you're having a great day!

Howdy, thanks for asking! Here are some fics that might fit what you're looking for!

Itty Bitty Brother by Warriorstale001 (Teen And Up, Incomplete)

After weeks of brainstorming, Dust believes he has finally come up with the perfect gift for Nightmare’s birthday. Sure, the guardian of negativity might not exactly like the idea at first, but Dust is sure it’ll work out in the end! He knows how much Nightmare wants the opportunity to talk to his brother without the threat of violence after all. Does it really matter if the only way to get that for him is to shrink Dream down to the size of a five inch tall bitty and trap him in a jar so he won’t be able to escape before the big day? No, he’s certain he won’t regret doing this by the end of the week. Nightmare just wanted a quiet, relaxing birthday with as little chaos as possible. However as soon as he’s presented with his now tiny brother staring fearfully at him from inside a glass prison, Nightmare realizes this isn’t going to be quite the birthday he imagined...

Frisk and Asriel's Special Day by NoSleepUntilVacation (General Audiences, Incomplete)

When Frisk and Asriel were nine years old, Toriel wouldn't let them go to Mettaton's New Year's Eve party. To make it up to them, Mettaton promised to throw a huge party for them when they turned eighteen years old. Now, the day has arrived, and everyone is determined to make it the best day ever! Based on the universe of Sunfreckle's "Happy Family", and written with permission. Most of the tagged characters won't show up in person until Chapter 3.

Birthday Bonefriend (Sans/Male Reader) by ComicalFont (General Audiences, Complete)

It's Sans' birthday! On top of that, you, his boyfriend and soul bond, get to enjoy the day with him for the first time. Alongside his brother, you plan to make Sans' day the most enjoyable it can possibly be. There is one nagging worry you can't shake off, though. Some of Sans' closest long-term friends have been invited to the house, and it'll be the first time they've seen you and him together. What'll they think about someone that caused Sans to shift from his single lifestyle to a deep relationship, and in less than a year's time? (Part of the A Skeleton's Connection story series. This can be read first, too!)

Metamorphosis by LasagnaForGarfield (Teen And Up, Complete)

During the days leading up to his twenty-first birthday, Papyrus experiences alarming changes: new powers, strange urges, and a deep, desperate hunger that Won't. Go. Away.

The Gift (Dream's Mr. Floofypants) by Aster_Smith_404, AsterSmith_404 (Teen And Up, Complete)

Its Nightmare and Dream's birthday, and Nightmare wants to give hes twin a birthday present! (Ft. Human Noot-Noot and Dream)

[askfallenroyalty]

Post was already wordy af but I wanted to elaborate:

Chara and Frisk share a soul

Asriel doesnt grow up right away

Main reason: I feel I lose sight of the og premise pretty quick as it shifts to drama and big plot points.

Having the kids all be able to communicate and spend time together as kids would work much better!!! And like, the time skip with Asriel leaving to be King still works its just happening slightly later in their timeline.

Its important to see the family, well, act as a family! I say no to plot getting in the way of that so soon! Give us time to enjoy just being back and alive T_T

Its my biggest regret (past the regrets I've talked at length lol) that the story inherently runs past them just getting a Happy Ending. Like it's too quick to get to the After ),:

But now to specifics:

#1 Frisk and Chara sharing a soul would neatly tie into soul lore in a more organic way. It forces that to stay in the focus.

It has the siblings work together. Structurally Frisk gets the short end of the stick being excluded from Asriel and Chara Flower and magic crap. Now Frisk is directly involved and on more equal ground. Regardless of larger story stuff, I do want to edit chapter 1 to establish a soul connection even if its more weak than this proposal.

This also makes Chara more on Team Human and less of a biological Dreemurr. Chara wouldn't be a flower boss monster, which I always felt was a bit too convoluted? Don't ask me how they have a body I haven't figured it out yet bro

#2 Golly I think Asriel being a kid would do a lot of wonders for the story I wouldn't even know where to start. While I like the "I grew up too fast because of what happened" angle as it's a cool metaphor, I think it'd be nicer to give Asriel a chance to be. Well, Asriel first. Let them be a kid for a while before becoming a corrupt king! Let them experience being best friends with both frisk and chara...

And like, to some extent I can have some of this happen in the continued rewrite version. I already have plans to fix some of these issues, but theyre also baked into the structure so that's why I'm kinda leaning into the idea of a real reboot. Like let's go gamers I wanna make this into a VN

[shattered-soul-au]

Asriel/Flowey/Sprout

He doesn't like the fact that he came back “wrong”

He has to relearn how to perform magic, as it's now a combination of physical and magical. Due to this, he has outbursts similar to how young monsters do at first.

He was still very much “Flowey” in personality when he first came back. It gets better with time, but he's still very cynical and sarcastic, as well as keeping the darker sense of humor as he gets older.

He dyes his fur for the longest time due to it being the same bright yellow as his petals as Flowey. As he gets older, he does it less, but still dyes it occasionally just because he can.

He gains attributes of his Omega and Hyperdeath forms when he uses strong magic. While most of them fade away once he's done, his claws have to be physically filed down, since they're naturally sharp anyway

His horns grow buds that bloom into golden flowers in the spring. He doesn't like them, though, so he tries to pull them off before then. He still tends to miss a few, though, so he usually ends up with a couple flowers on his head anyway.

He finds vines and plant magic in general easier to use than the fire and healing magic he had before. He dislikes it for the longest time, and struggles to perform his old magic, anyways. Though he later accepts this as a part of him.

He gets frustrated that he can't grip things with his claws as well as he could with paws. He has to ask for help with certain things due to this, which irritates him further. Though as he starts accepting his magic, he learns to use his vines to help him.

His vines tend to sprout from his paw pads, which are still plant-like

He can't face shift anymore, but can still mimic voices. He does it on accident sometimes, but doesn't like the fact that it happens. Though once he realizes that Frisk finds it cool/funny when he does it, he starts doing it more for them. Over time, he accepts it, and it becomes a normal thing for him

Him and Chara aren't as close as they used to be, but they still love each other.

Him and Chara like to get on each other's nerves, but in a friendly way. They tend to get pretty aggressive with it, and verbal fights often turn physical, but nobody really gets hurt.

He really admires Frisk, to the point of putting them on a bit of a pedestal. He often forgets that they've done bad things, too.

He doesn't have memory of the timeline that Frisk and Chara came from, but he knows of it.

He disliked Rory for the longest time, as he felt like they were just a replacement for him, but eventually forms a decent relationship with them.

He hates being expected to act like he used to, even though he has the same expectation for himself at first.

He's close friends with Clover and they spend quite a bit of time together

He's never actually said a swear word, and he's honestly too afraid of Toriel's reaction to do so

He goes by the nickname Sprout for a while due to not really feeling like he should be called Asriel, but still feeling different from Flowey, but eventually feels alright being called either, though Clover still tends to use his nickname and most just call him Asriel

He doesn't want to be king when he grows up anymore, and just wants to live as normal a life as he can

His "fur" is actually just plant fibers, kind of like dandelion fluff. It doesn't actually retain much heat, and Asriel doesn't do well with cold weather.

Random's Lore Drops - Sand Under Table (FR this time)

Alright, so basically, i hate my shitty sans lore drop so i'm making a real one. Ready? Because it's time for...

Cursive, Cursive the Skeleton. Wait what do you mean it's not Cursive? Oh, Sans? sorry. Sans, Sans the Skeleton.

Time to rant. Like, REALLY rant. So, Sans The Skeleton. You know him, you love him, or you hate him. I'm in the middle-ground. I don't give a fUCK about that twat. He's the face of Undertale (but most definitely not what defines it), as well as the first person you meet in Snowdin, excluding Mister Camera which people usually miss (it's in the bush right as you exit). He's a comedian skeleton who likes to play pranks, and also tells over half as many puns as Papyrus (wild ain't it?). His first introduction is not at the gate, but instead the walk to it, where you get to watch his shadow move around as you walk, and also watch as he snaps a stick with ease (don't ask how). As you might know, he's completely nihilistic, and refuses to fight you until you actually end up being a threat. That's right, first degree murder on everybody except those two Froggits you forgot about in the Ruins makes you not a threat, but a Genocide route does. Why? Well, it's simple. You become a threat to the timeline. Now, it's to note he DOESN'T remember resets, only being able to tell by Frisk's expression (which is not related to your input). He also doesn't have the deja vu that others have, instead noting down things during resets, like Frisk turning around before he tells them to, and them acting like they did everything before. He DOES, however, state that there are reports of timelines shifting left and right, which means he has some sort of machine to tell. It's pretty known, but the reason he doesn't kill you isn't out of laziness, but instead, having a promise. He outright tells you that he'd kill you in a paci/neutral route during the "date" with him. He is CANONICALLY only friends with Toriel, and even then, he never knows her name until the pacifist pre-ending cutscene, before Asriel. sans.™ literally could not give any less of a shit, but because he knew Toriel for a while, albeit due to the power of knock-knock jokes, he ended up accepting. He also states that he HATES making promises. His attitude really tells a lot, as, even in his boss fight in the Genocide route, he does not give a SHIT about it. He constantly looks like he's joking, and he does NOT act overly emotional in any situation, with the most emotional that he gets being to tell yourself to politely go fuck thyself by telling you to burn in hell, and calling you a dirty brother killer. He still CARES about people, he just rarely shows it. That "dirty brother killer" line really shows it. After all, how would YOU feel if broke into YOUR planet, into YOUR country, into YOUR town/city, and killed your only family member and then said I was above consequences for that. ...Ignore the "your planet" line. Trust me I come from Earth. It's also shown based by his room that he is NOT a clean person. His first stand stinks of condiments, he sells hotdogs at his own stand, and it's assumed that he LITERALLY has the exact same stand everywhere, based on the snow on the roof, which never disappears in any instance of his stand (stand, IS THAT A JOJO REFERENCE?!?!?). His only role, aside from comedic relief, is the final Genocide boss (which he is known as), and the guy to judge you before you go to Asgore, since that is his only role. Now, onto personal hate. People DON'T realize that he's not fucking FIGHTING you because you're a threat to the kingdom, but because you're going to ERASE the timeline, and when something's erased, it usually never comes back. It's because of the timeline possibly being erased forever, in which he fights you and tries to off you. He doesn't know about the "deal" that the Player makes with Chara, in which you trade your SOUL to recreate the timeline from square one. (my personal headcanon for if Sans ever remembers you're genocides is to go fuck off elsewhere, since there's no reason to fight, right? After all, you're not permanently erasing the timeline, he has no reason to fight. It may be erased, but it keeps coming back, even if YOU don't recreate it, because another Player will.)
