Okay, My first Adventure Time Fanfic peeps. Please enjoy. Also it is supposed to be the land of Uuu for the time being. This chappie is pretty slow-moving, but the plot will begin to accelerate after this.

I don't own Adventure Time


Land of Uuu: Year 2XXX, Pre-Mushroom War

A sleek, black limousine screeched to a stop in front of a Victorian-style mansion. Elaborate tiered arches adorned windows and walkways while ivy crept up the white brick walls. As a butler opened the door to the window, a small girl emerged. Walking up the grand stairs with some struggle, the girl approached the awaiting family at the entrance. The owner of the home, a stiff man in a starched suit, rigidly motioned to the girl for the young boy standing beside him.

"Finn, this young lady is Fionna. She will be your sister from now on, do you understand?" the father barked. The boy beside him, known as Finn, looked up timidly towards the girl. His mop of golden hair slightly shadowed his curious blue eyes. His button down shirt and vest seemed to be of very high quality.

Clutching and hiding behind his father's pant leg due to shyness, Finn muttered, "H-hello." The girl at the doorstep returned the same curiosity. Her hair was of the same golden hue and tumbled down in waves until it reached the middle of her back. With a simple outfit of a white shirt and tattered blue overalls, the young girl stuck her hand out enthusiastically.

"Hey! Nice to meetcha!" Fionna responded with a smile that stretched ear to ear. Inching out from behind his father's shadow, Finn gradually accepted the girl's gesture and gave her hand a small shake before quickly releasing it with a hint of a smile.

Opening the large redwood doors that led inside to the house, Finn's father ordered them to hurry inside.

"Show Fionna around, Finn," he commanded as he went up the curved double staircase and retreated into his office.

"Yes, sir," Finn replied obediently as he turned to face Fionna. The girl had a face of bewilderment as she scanned the entryway. Swirled marbled floors accented famous paintings that hung on the walls. Seeing as it didn't appear the immobile Fionna would be capable of moving any time soon, Finn gently grabbed hold of her pudgy hand and tried to lead the girl up the grand staircase.

"Come on!" he insisted with growing enthusiasm, a smile spreading on his features, "I'll show you around!" Finn wasn't allowed to raise his voice within the household, but something about having this girl, this bubbly creature, as his sister filled him with overwhelming happiness.

Shaking out of her trance, Fionna bounded behind the boy as he approached the room that would be hers.

"This is your room…" he murmured quietly as he turned the doorknob and creaked the door open. Behind the door lay a pink masterpiece. A canopy, queen-size bed lay in the middle of the room with an excessive amount of frilly pillows and blankets. In a corner, a dollhouse and dress up clothes sat ready to be played with. Scrunching up her nose and quickly closing the door so she couldn't see anymore of the hideous room, Fionna tried to hide her distaste.

Not wanting to be ungrateful, she slowly ventured, "Can I see what your room looks like?" Finn nodded and led her down a carpeted hallway to the room at the end. Opening the door, the room gave an aura quite unexpected of Finn's current personality. A plain bunk bed leaned against the farthest wall while a locked weapon's case hung against another wall. At a desk beneath the rack was a globe, scattered paper, and various worn books.

Tapping her shoulder, Finn placed an iron helmet on Fionna's head which was far too big for her and covered her eyes. Using her hand to lift the helmet up, Fionna peeked underneath the lid of the helmet and saw Finn pressing a finger to his lips.

"You see…" he whispered secretively so Fionna had to come closer to hear him, "…I want to be an adventurer when I grow up…." Fionna's blue eyes widened in surprise at the now cheeky looking boy, she had thought he was a stuck-up, preppy child, but he appeared to be quite the opposite when he wasn't underneath his father's shadow.

"Shmow-zow!" the young Fionna exclaimed, "Well, Finn, I believe we have some rad adventuring to do in our near future… But first thing first, is that top bunk of that bed occupied?"


Finn's father kneaded his scrunched forehead with his hand as he tried to relieve his stress-induced headache. A teenage girl sprawled across his desk grabbed an apple out of the bowl, and tossed it away when she had turned it wrinkled and gray. A teenage boy of similar characteristics thumbed through various books along the office's bookshelf.

"Would you two please stop messing around!" Finn's father demanded as he crashed a fist onto the hardwood desk, "With the tension between the countries increasing each day, nuclear warfare could ensue at any moment, and you two are dillydallying while the lives of my children are at stake!" The girl spread across the desk glanced at the man out of the corner of her eye.

"Cool your pots, Pops, we got this," the girl reassured as she motioned for the boy to soothe the raging man as well.

"Yeah, old man, Marcie and I have things covered. Isn't your scientific creation almost finished anyway?" the boy contributed before returning his interests back to the shelf. Finn's father sighed once again. The existence of humanity was at stake here and these two, who were indebted to him, couldn't seem to care either way. He just would have to pray for the safety of his children and hope that a miracle would happen.
