Chaos Cipher

Chapter 1. Sleepover

" Rawr! I am the evil witch of the western forest!"
Chaos Cipher and Mabel Pines were playing in the grass near the Mystery Shack. " I will defeat you, evil witch lady!" Mabel declared, swinging a long stick covered in glitter at Chaos. " Haha! Never! Behold my, uh, powers!" Chaos set Mabel's stick on fire, and laughed.
" Hey! My magical stick! Well, I don't NEED some glitter wand to defeat you....Rah!!!" Mabel tackled Chaos and pinned her to the ground. She wiggles for a second, then went completely limp. Chaos was immensely powerful and strong, but she always let Mabel tackle or crash into her, as well as not even trying to escape Mabel's grasp.
" You're not even trying, are you?" Mabel asked. She had positioned herself on Chaos' back, and was sitting on her, as if she was a chair. " Nope." Chaos snickered, before suddenly rolling over, and sent Mabel flying into the sky. Mabel shrieked, but she wasn't terrified. She knew that Chaos would catch her, and would never let Mabel fall. Then, Mabel was sent plummeting down into the ground, but before she could crash, she was suddenly levitated, and gently landed. " I was trying then." Chaos said, grinning at Mabel with amusement. " Yeah, well, you have magical powers. And strength." Replied Mabel.
They talked and laughed until suddenly, the clay above them darkened. The two girls looked up, and saw Bill Cipher, staring at them.
He studied Mabel, obviously suspicious. Then he turned his gaze to Chaos.
" Chaos....are...you playing with shooting star..?" He asked slowly, and he towered over her, casting a triangular shadow above them. Most people would be terrified of Bill, and it was common that if they looked him in the eye, they would go insane, or die from terror of what they saw. But Chaos stared right into her father's eye, obviously not bothered in the slightest. " Yes, dad. I'm playing with Mabel." She answered.
" What did I tell you about...never mind. Anyway, Kill and Tad are coming over to spend the night at our place. And I don't really think you should be there, so...(sigh), can Chaos sleepover at the Stupid Shack tonight?"

"EEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEE!!!!!!!!!!!!!!"
The two girls shrieked excitedly,and grinned at each other. " Yes! Yes! Chaos can TOTALLY sleepover tonight! Dipper probably won't mind!" Mabel exclaimed happily. " Whatever. Chaos, you don't need to pack. I mean, we can pretty much create anything we want, so...um, let me give some rules: NO trusting Stan or Ford or Pine Tree or Shooting Star. NO friendship bracelets, AND NO HUGS OR ANYTHING INVOLVING HUMAN CONTACT."
Chaos rolled her eyes, and sighed. " Fine, dad. Bye."
With that, Bill disappeared, and Mabel and Chaos were left standing alone in the dark.

Chaos and Mabel went inside, and the two chatted away. They didn't even notice Dipper staring at them. " Mabel!! Where have you been?! Grunkle Stan and I were so worried!! Actually, Grunkle Stan was watching TV the entire day, so he probably didn't even notice you were gone....But I was worried!"
Then Dipper glanced at Chaos, and slowly backed away.
" Mabel....who is THAT?!"
