In a dark room that has cleaning supplies, a toolbox, a broken table, and light bulbs. In the middle of the room was a pair of twins, a brother, and a sister. The brother wore a blue cap with a pine tree, and the sister wore a violet with a shooting star symbol, but they wore the same blue and yellow jumpsuit. The brother begins to wake up.
"What happened?" said the brother, rubbing the back of his head. He looked around to see where he was, and then he started shaking his sister. "Mabel woke up."
"F-five more minutes Dipper," said Mabel, still asleep
"Mabel you've got to wake up now." Dipper shakes more until Mabel was woken up
"What is it Dipper another-" she stops what she was saying and looks around where her brother is at. "Dipper where are we?"
"I have no idea, I'm sure we're even in the mystery shack."
"The last thing I remember was going to hang out with Candy and Grindu then everything else was a blank."
"Same here."
Mabel looks down at her jumpsuit. "How did I end up wearing this jumpsuit?"
"It seems someone put these jumpsuits on us."
"But why?"
"I don't know Mabel I'm about as confused as you right now."
Mabel sighs. "So what now?"
"I think we should get out of this room and look around to see where we are."
Dipper and Mabel leave the room to see metal hallways that have some rust, and they see a door with a yellow stripe with the number 26. The hallways were quiet and with signs of life present.
"Dipper this place is creepy," said Mabel
"I know Mabel let's keep searching," said Dipper
Dipper and Mabel search around an unfamiliar place with more metal doors with the number 26. They reach a door with a sign that says "workshop," and the twins go inside to find two watch devices on a table.
Dipper picks up, "I wonder what this thing is?"
"It looks like futurict watch," said Mabel
Dipper turns on the watch, and the screen says, "Pip-boy 3,000 and ready to be used."
Mabel grabs the other Pip-boy and puts it on the watch.
"Mabel why did you put on the watch?" said Dipper
"Well it's cool and I could be useful." Then, after that, she turns on Pip-boy and shows Mabel her location "we're in Vault 26."
"A vault? what type of vault is this?" said Dipper. Then Dipper looked at his Pip-boy and saw the exit to the vault "let's just get out of this creepy place."
"I'm with you on that bro."
The two make their way to the vault door, and they see a corpse wearing the same jumpsuit as they are and holding a pistol in the right hand. The twins ignore the corpse so they can move forward. Eventually, they reach the vault door.
"Woah that's a big door," said Mabel
"This must have been a massive vault," said Dipper
"So um how do we open it?"
"Crap your right we need to find a way to open it."
"Maybe there's some passcode or something to open it."
Suddenly the vault door begins to open. The sun rays came through the vault. On the other side was a tall woman with black wavy hair. She wore black leather clothing with her own Pip-boy and held a semi-automatic rifle.
When she looked at the twins for the moment who were holding their hands in the air, she said, "what the fuck is this?" the women stepped inside of the vault, "what are you two the vault residents?"
"Um no we're not," said Dipper
"Can put the gun away miss," said Mabel
The woman groans and puts away the gun "how did you two get in the vault?"
"We have no idea we just woke up here."
"Uh huh."
"Are we still Gravity Falls?" said Dipper
"Gravity Falls? Never heard of that place."
"It's in Oregon, wait is it even in Oregon?"
"No, you two are in the Mojave wasteland,"
"Wasteland?" said Mabel
The woman pinches the bridge of her nose in annoyance. "Great now have to deal with this," she thought, then said to the twins, "look I know you two are probably confused I'll help anyway I can but I need to get something out of this vault. You two can wait here or tag along."
Dipper and Mabel look at each other for a moment, and Dipper speaks for both of them. "We'll tag along with you."
"Fine but don't slow me down."
"Um miss what's your name?"
"My name is Courier. What's your guy's name?"
"Dipper," said Dipper
"Mabel," said Mabel
"Alright Dipper and Mabel follow me," said Courier
The twins follow the Courier in the vault with no idea where they are at.
