This was worse then the time that he lost her all those years ago...

Nightmare was hyperventilating into a brown paper bag, even as Error tried to calm him down, snapping at Dream when he got too close to them.

Cross was glaring at Dream, they didn't have the time for this!

Dream had ambushed them while Chaos was on the way back from visiting her home AU, one thing had lead to another and by the end of it, Chaos had been sent flying into her half closed portal which sent her somewhere else.

She had only just gotten the hang of creating portals, so who knew where she was right now?!

Nightmare had lost it when five minutes had passed and Chaos hadn't shown up. He started to scream at Dream, before he curled up into a ball, hyperventilating into the brown paper bag that Error had given him.

He couldn't even sense her emotions!

Dream wasn't even helping with his positive aura, it was making things worse and sending Nightmare swirling deeper into his own head.

Cross eventually knocked Dream out, before they made their escape, their was a possibility that Chaos took a portal back home, instead of coming straight back to them.

She still hadn't learnt how to control her urge to strangle Dream, until he was out cold, or he had learned some common sense.

-------

Chaos groaned as she woke up. "I am going to kill that Annoying Sunshine Idiot." She picked herself up, brushing off the dirt and dust on her body and redoing the ribbon that was keeping her hair back.

It seemed that she had been transported to another AU, but she didn't have the time to explore it, she needed to go back home.

She raised a hand up, intending to summon a portal, when the ground underneath her feet started to shake.

She lost her balance and she nearly fell over, but she regained her balance, before she looked at the sky above her.

The wind around her was starting to pick up, something was wrong. There was nothing wrong with the sky, but she couldn't help the sinking feeling that she was getting in her bones.

If this was a trap meant to kill her, like the last one, she was going to kill Dream when she got her hands on him.

The heavens above her burst, and a deluge of rain soaked her to the bones, even through, there wasn't a cloud in the sky.

Chaos quickly started to run, looking for the nearest shelter, even as the dirt around her became mud.

-----

She eventually found a shelter in a cave, and she wasn't the only one. There was other monsters here.

Most of them looked like that they had came from a Fell AU, but Chaos had not seen a lot of Fell AUs, but she could recognise the Swap Monsters with them.

They weren't from her AU, but she could clearly see a Papyrus cradling a sick looking Sans.

She winced when she saw them staring at her.

"Hey Kid." The Papyrus said. "Your AU got dragged into this mess too?"

Chaos was confused, but she still answered. "Nah, I don't think so, I'm kinda an Outcode. I still have an AU, but I prefer to live outside of it."

She slowly shuffled away from the Swap Monsters. "I'm just going to find a random corner and sleep in it for the night...."

"Your Papyrus wasn't kind to you, wasn't he?" Papyrus threw a blanket at her that she caught. "The Fells have the left side of the cave, and we have the right side, there should be a corner deeper in the cave, but don't go too far, the deeper caves were claimed by the survivors of this AU."

Chaos nodded her head, even as she made her way to the corner, clutching at the necklace around her neck.

'I wanna go home.' She tried to summon a portal again, but it didn't work. She was trapped here.

--------

Things went from bad to worse.

This AU was a Horror AU.... Chaos had been scared of Horror AUs ever since the Blue on Dream's side had used a portal to send her to a Horror AU where she was nearly eaten...

She shivered underneath her blanket, even as the Papyrus picked her up so that he could move her to the Swap side of the cave.

The Horror Monsters were starting to act weirdly, something was wrong....

The sudden boom caused most of them to scream.

"Into the Deeper Caves!" Papyrus yelled, picking up both of the Sanses. "And seal them behind us!"

The sick Sans clung to his brother as he ran and Chaos was shivering, holding onto her necklace tightly, chanting a prayer about the Tree of Feelings.

The running Monsters sealed the caves behind them, and they settled down to wait, but even down here, they could still hear the booms....

"Papy..." The Sans sobbed, burying his face into his brother's hoodie.

"Shhh... Sans. Everything is going to be okay." Papyrus told him. "We're going to be okay Sans, I promise."

Chaos fell asleep to the sounds of war.

---------

Everything had changed again when she woke up. The air felt different, it was heavier and for every breath that she took, she felt like she was choking.

It seemed that some of the other Monsters had been too slow to keep up with the rest of them. She couldn't see them anywhere.

The Monsters were mainly grouped together depending on which AU that they came from.

The Horrors had taken the more darker parts of the Deeper Caves, the Fells had taken the more defensive part of the Deeper Caves, while the Swaps were right in the middle of them.

Chaos shivered, she was so cold, even with the blanket around herself, she just wanted to go home.

The ground softly shook underneath them, waking a lot of the other Monsters up.

Whatever had caused those booms earlier was still alive and active....

Chaos started to chant her prayers again, in an effort to calm herself down, she didn't understand why she felt so heavy and why it hurt to breathe, nothing was wrong with her...

The ground slowly calmed down, and nearly every Monster there looked at each other, was it worth the risk of checking that it was over? Could they be sure that it wouldn't start up again the moment that they undid the Seal?

A hushed discussion broke out between the leaders of the three sides, they were really unsure about this...

Chaos just focused on controlling her breathing, and with every breath, it got easier for her to breathe.

But eventually, it seemed that the leaders had reached a decision, the Seal was undone, and everyone started to slowly shuffle towards the entrance.

Chaos kept the blanket wrapped around her shoulders, it was strange that it was so dark right now.... She knew that she had slept through the night, where was the Sun?

"May the Angel save us all....." The Monster at the head of their group muttered when they finally saw the outside world. Chaos was confused and she was very worried at the same time.

"Papy..." Sans was crying, it seemed that he had seen something that wasn't right....

Chaos slipped through the crowd and she gasped when she saw the outside world....

It was so grey... The sun was gone, hidden behind clouds that weren't there before....

And it was empty, the forest that she had been running through earlier, was gone, just like that....

Just.... what was going on here? This wasn't normal.... Just... How many AUs were pulled into this mess? How many of them were going to die?

She didn't want to die again! She still had scars from her first death, as a human, and from the time that her Papyrus Dusted her....

But they all stopped when they saw a pile of dust, by the shattered remains of an axe.

"Shit..." Chaos hissed. The Sans of this AU was dead and she didn't know what this fusion of multiple AUs was doing to the Resets......

Wait, two or even more AUs fusing together, meant that the human population exploded....

And most counties had access to nuclear weapons....

"Fuck!" The humans had killed each other, and while Monsters would survive the fallout, the radiation would have weird effects on a lot of the Monsters....

She did not want to know that would affect everyone here...

Wait, if the Sans was dead, who was stopping the AU from corrupting and collapsing on itself?

She had no clue if there was any other Sans here, apart from her, and the sick one...

But the heavy weight on her shoulders wasn't going away....

She had a feeling that it never would.

------

It was surprising how quickly their group had broken apart after they got out of the caves, the Horror Monsters scattered themselves all over the place, the Fell Monsters went back into the caves, and the Swap Monsters spilt up into smaller groups.

Chaos snuck away from her group when the chance came, she had no problems with the Swap Monsters, but being too close to a Papyrus was bad for her. She still had the scars from her Papyrus and his treatment of her...

She just couldn't accept the idea that a Swap Papyrus could be nice, she knew that it was possible, but to actually see it, had opened up a lot of old scars....

She just wanted some time alone, but she did return the blanket before she left the group.

She couldn't stay with them...

She walked on, just letting her feet choose where she was going...

She couldn't see the stars and that bothered Chaos the most, she had always had a connection with the Stars, starting from her first life, and even today, she still had that connection...

She sighed, even as she tasted the grit in the air as she breathed.... So much had been lost, and no one knew if they could get it back....

She stopped walking when she heard a growl.

She quickly turned around, summoning a bone attack, to see what looked like a Greater Dog?

This wasn't going to end well... Chaos found herself sweating, even as she summoned more bone attacks, but the Greater Dog like creature seemed to be more interested in the bones....

"Errrrrrr...... Fetch!" She flung several of the bone attacks as far away from her as she could.

She started to run for her life, even as the Greater Dog like creature went after the bone attacks.

------

She eventually found some form of shelter in a ruined building. It wasn't a building that she recognised, it had been twisted and broken in the fusion of the AUs.

It wasn't the best shelter that she had, but it was good enough.

The building was on the edge of the remains of what had once been a city, and she could hear noises at night. Was it more of those dog creatures or was it something else?

But no matter how much she wanted to, she couldn't summon a portal to take her home. There was several more earthquakes, the crushed together AU fusion was starting to calm down, but Chaos clung to her Blaster Hammer whenever she had to make a supply run. She had built up quite a lot of supplies, but it was getting too dangerous to stay in the remains of the city, the creatures were getting closer to her shelter.

It was after a close call that she had to leave.

Chaos winced as she carefully placed some of her weight on her bruised left ankle as she walked. She had nearly gotten herself killed one night because she had been careless.

The clouds still blocked out the sun, but at this point, she had figured out how to tell the difference between night and day.

She wandered away from the city, taking everything that she had managed to find with her. The supplies would be useful.

She wrapped a scrap piece of cloth around her skull and her mouth as she walked, blocking out most of the dust and the ash.

She didn't see anyone as she walked, so seeing the creature made out of fire in a cave system that she was going to sleep in, was a shock.

But it was a welcome relief at the same time, she thought that she would be alone, trapped here forever, for the rest of her life...

"Hey.."

The fire creature jumped, turning around, only to stare at the Sans, before she smiled. "When did you get here Stranger?"

"I have been here for a while." Chaos sat down next to the fire creature. "I actually just got here, thanks to an accident with a portal, before things went boom."

"So, you survived 'The Crush' then?"

"The Crush?"

"It's what some of the other survivors have taken to calling the moment where everything just fell apart." The fire creature looked at Chaos. "And you're actually holding up pretty well, considering you are actually keeping this place from getting worse...."

"Yeah, you tend to figure that out when you have time to think and you have to adjust to a new weight on your shoulders, plus, what else could I do? I don't even know if anyone is coming to help us..."

"Others can get in, but they can't leave, and a lot of them have tried to do that...."

"So, there are other Monsters here?"

"I'm setting up a town in this cave system, it won't be much but it's all that I can do, I can't do anything more then that..."

"That is actually a lot better then doing nothing...." Chaos placed her hands behind her head. "Do you have room for one more, I may have hated it, but I do have Royal Guard training...."

The fire creature smiled. "So, which AU and Multiverse do you come from then?"

"There is more then one Multiverse?"

"Yeah... All of the AUs dragged into this, come from three different Multiverses, from what I know so far...."

"So.... There are Dreams that are not giant pricks with wings?!"

----

Time passed and more Monsters started to slowly make their way to the town that Fire was setting up.

The small town itself was slowly growing and a year after it began, Fire opened her bar while Chaos finally managed to set up a rough Guard for the small town, giving command to an Undyne, before she quietly slipped into a sentry position.

She occasionally went out to get more supplies during a longer patrol, and during one of these runs, she met Greytone.

-------

The Skeleton that she had found was covered in endless grey ash and dust. He was bleeding from his skull and he had collapsed on the ground.

But, he wasn't Dusting from how hurt he was....

She picked him up and she ran straight back to the small town that still needed a name....

This is actually an Interlude for Firehedgehog's Code of the Soul. My Swap!Chaos is actually a character in that story. This is how she ended up in that story.

I actually have plans for Dreamswap!Chaos AU - Swap!Chaos - Missing, to become a small series of stories focusing on what happens to the Meme Squad, and the others, while Chaos is trapped in this fusion of AUs.
