Frost: Hello everyone and welcome to my very own Undertale AU called Daemontale. This AU is centered around the idea that every character in Undertale has a daemon, a part of their soul walking beside them. If you have any questions feel free to ask and yes, I am working on the next chapter of AMSWBM as we speak. For now, though, enjoy chapter one of my very own AU

Sans: Frost doesn't own any of the Undertale characters, they belong to Toby Fox while the concept of daemons belongs to Philip Pullman

Papyrus: PLEASE REVIEW OR PM IF YOU HAVE QUESTIONS AND ENJOY

Ever since he had been little, people had always had something to say about Sans and his daemon. Not that they cared much of what others had to say, as long as they were together everything was perfect as far as they were concerned. But that didn't mean they didn't hear the whispers. In some ways, Sans could understand why they talked, why they were somewhat disturbed and frightened. As far as anyone was concerned Sans and Caellian were the first in recorded monster history to be the same gender as each other. While it didn't bother them too much it did make it kind of hard to make friends what with superstitious parents warning their children to stay away from the cursed boy and his unnatural daemon. Thankfully they had Papyrus and Amarisa by their side every step of the way. Papyrus, though possessing a normal daemon also finds it challenging to make friends due to his naive and simple-mindedness as well as his outlandish beliefs that even humans must have some good in them. His views and morals have long since ostracized him from other monsters and it has never helped that he is the twin brother to the supposed cursed child of the underground.

Amarisa, despite longing for more companionship, was also a bright and bubbly soul who stayed by Caellian no matter what. She truly lived up to her name which translated into 'Given by God' as she truly was a God send to all those that knew her. She was also the only daemon that could get Caellian to come out of his shell and play like most children's daemons would. However, despite their valiant effort Sans and Caellian tried to not be seen with Papyrus and Amarisa as much as possible so they could hopefully make new friends. After all, Amarisa was the perfect daemon, she reflected Papyrus perfectly in every form she took and they were all considered normal for a child Papyrus' age. She often favored dog forms which were symbolic of loyalty and kindness, something the adults approved of greatly. Sans and Caellian, however, didn't much care for the norm.

Caellian liked dangerous forms, ones that could frighten others and defend himself and Sans if needed. It was fine for a monster's daemons to settle as a dangerous form later in life, but for a child to have a daemon with a dangerous form almost constantly was seen as unnatural. Sans hardly cared, though, if it made Caellian happy then it made him happy. Eventually, it all seemed to calm down when the adults realized that it was just Caellian being Caellian and they let it go. Trouble started up again though when Sans turned eighteen and Caellian finally settled.

Amarisa had settled two years previously when Papyrus and Sans had been sixteen, taking on the form of a golden retriever with sky blue eyes. Everyone was happy with the form; it was simple but it fit Papyrus perfectly. Undyne, one of Papyrus' closest friend's daemon settled only a few weeks after Amarisa. The warrior fish and her daemon, Ferdiad, settled on the form of a small dragon. His scales were a deep blue while his eyes were obsidian. And while he could swim just fine he still breathed fire which would glow blue as well. If Undyne had been human, Ferdiad's form would have caused a great upset as mythical creatures weren't common among humans. Monsters, however, had both equal chance of having a normal daemon or mythical. And with dragons symbolizing strength and might everyone agreed that Ferdiad was perfect for Undyne in every single way.

Caellian, however, was not perfect in their eyes. He was a late settler, Sans had even believed for a while that perhaps they would never find the right form. But that all changed when Sans, practicing his magic had summoned a Gaster Blaster head catching Caellian's attention. The daemon, in the form of a white tiger, had sat up and shifted. His head was the same as the one Sans had summoned but his body looked like Ferdiad's only without wings. His claws were huge and teeth long making him look incredibly dangerous while his long tail was tipped with a spear-like end. Sans and Caellian made eye contact, and just like that it felt like something just slipped into place.

"So this is us then?" Sans questioned while petting Caellian's muzzle. His daemon towered over him by at least three meters which in itself made him look even more threatening.

"Are you upset?" Caellian asked in return, worried his other half would detest their true form. After all, they already were different from other monsters, this would just cast them out even more. But Sans had smiled and hugged Caellian's muzzle to his chest, eyes closing in peace.

"We're perfect in every single way." Was all he said in return. It did the trick though for Caellian relaxed and gave a deep rumbling growl that sounded suspiciously like a purr. When they walked back into Snowdin people screamed and yelled, pointing fingers at the terrifying sight that was Sans and Caellian. They didn't even bat and eyelid at the near comical display and instead headed home, Caellian having to squeeze through the door of the house. Amarisa barked loudly in greeting before bounding over, sniffing at Caellian while Papyrus watched on with wide eyes.

"This is different," Amarisa commented while staring up at Caellian who huffed.

"It's a good different." He said.

"Is it a forever different?" She prodded and he tilted his head, Sans watching the entire thing with half lidded eye sockets.

"Yes, I believe so." Caellian finally said making Amarisa and Papyrus blink in surprised.

"Is this okay?" Sans asked warily.

"Yes, it will take some getting used to but I think you both look wonderful. I'm sure it suits you both very well brother." Papyrus beamed ever the happy and kind one. Amarisa nodded along with him, gently nuzzling Caellian's head with her own when the massive skeletal creature lent down to greet her properly.

When word got out about Caellian and Sans' settled form judgment and speculation spread like wildfire. It was one thing for a daemon to settle as a mythical creature, it was another thing entirely when a daemon settled as something that technically isn't even a thing. If people discreetly avoided them before they now didn't even try to hide their discomfort or fear as they turned around and ran in the other direction. Sans would sometimes feel a slight ting of hurt at their actions, after all, couldn't they understand that Caellian was perfect just the way he was, but he always pushed those thoughts aside when Caellian would gently bump his massive head against his body. Sometimes it would nearly topple him over but then Caellian would use his tail to right him once more. All in all, they were perfect together, working as two halves of one unit.

"Ever think of joining the royal guard?" Undyne had asked one day when they were visiting her. Papyrus and Amarisa had convinced Sans and Caellian to tag along to their training session and they had opted to stay for lunch as well. When Undyne asked that question however both skeletal monster's tensed while Papyrus and Amarisa looked at them worriedly.

"Why would you ask that? Is it just because Caellian is large and dangerous looking, like some trained attack dog?" Sans hissed, his sockets turning completely black while Caellian gave a rumbling growl.

Undyne shifted nervously, Ferdiad sat up from his place around her shoulders to growl right back at the enormous daemon. Like Amarisa he lived up to his name which meant protection. He had also been named after a Celtic warrior who had been a brother in arms to a king. Seemed fitting seeing how he and Undyne were head of the royal guard.

"Your also well trained in handling your own magic and quite powerful too Sans. It's not just about Caellian's form, though I will admit it is partly the reason." Undyne muttered while placing a soothing hand on her daemon's head.

"Though an admirable carrier, it is not for us. We would rather spend our time doing something we enjoy." Caellian huffed not caring at the way Undyne flinched at being addressed by someone else's daemon. Ferdiad gave him a warning hiss before curling up tightly around his girl's neck offering comfort in the only way he could, through physical contact.

"Besides, the royal guard is Papyrus and Amarisa's thing." Sans added on with a smile directed to his brother. Papyrus returned the smile though he and Amarisa seemed tense, after all, they could tell that Caellian was not happy with the conversation topic. It isn't until they are walking home and are away from other monster's that they confront them about it.

"Why don't you want to join the royal guard? What's so bad about it?" Amarisa asked, bounding around Caellian like an excited puppy. The skeletal dragon like beast growled slightly but didn't raise a paw against her.

"I will not be some trophy for them to parade around. They look at me and only see power and something to be controlled. I am not an animal, I am so much more." Caellian sneered, teeth bared for all to see. Amarisa however didn't even flinch at the threatening sight. Instead she bounded forward and placed her paws on Caellian's muzzle and gave it a few licks.

"I know you're not an animal Caellian and don't worry, one day everyone else will see what we see." She assured him. He gave a weak huffing growl, blowing warm air onto her face in a sign of affection.

"Do you feel the same Sans?" Papyrus asked as he watched Caellian lie down onto his side allowing Amarisa to curl up against his ribs.

"In a way yes. The rest of the underground isn't as accepting as you and Amarisa Paps. When they look at Caellian and I they don't see a monster and his daemon, they see something that is different, something they don't understand and that scares them." Sans said as he too watched the interaction between the two daemons. He felt a gentle hand on his shoulder and look up into his brother's eyes that were filled with hurt and sympathy.

"Don't worry, like Amarisa said one day everyone will see what we see." He said before pulling Sans against his side. The smaller brother chuckled, nuzzling into his brother's stomach.

"You're a great brother Paps, you take such good care of Caellian and I." Sans sighed happily feeling Caellian's own happiness flowing through the bond. Papyrus chuckled at his comment, gently nudging Sans with his hip.

"Well, I am older than you." He teased which had Sans giving a soft grumble.

"Only by 36 seconds." He argued back.

"Still counts."

They didn't have many friends, and most of the ones they did have were still wary and slightly frightened of them. But that didn't matter to them. As long as they had Papyrus and Amarisa by their side they were just fine and perfectly happy. Besides, Papyrus and Amarisa were the best company they could ever ask for in the end.
