Chapter 1

Prologue:

Marshall opened the fridge door for the fourteenth time.

"Bah…" He sighed, closing it. No new food had magically appeared in it. How inconvenient.

Every couple of centuries, there came a decade which took forever to pass by. Not that this was necessarily a bad thing, his life was pretty good right now. He had his friend groups, the weird Immortals Anonymous club that PG ran every month which kept him busy in writing little diddies about existentialism, he had his cozy little house, and all of his mortal buddies. He sighed, thinking of one mortal buddy in particular. He recently had developed a fondness for love songs, harnessing hidden feelings for someone who was probably rage playing through the entire game 'Battle Castle' again on BMO.

He really had tried to tell her, to get a hint if she liked him too. But it was to no use. Even if he felt her heart race at his advances, her violent reaction afterwards always muddled his 'like-like' radar. The whole situation made him just a bit impatient.

Marshall opened the fridge door again, and sighed. Same old.

A rumbling happened beneath his feet. What was this, an earthquake?

But then a horrific emotion overwhelmed him. A severing of sorts, and it came from the Nightosphere.

My mother has been killed… Thought Marshall. There was do doubt about it. Her presence was cut from him, and he felt her complete absence in the world. A shiver ran throughout his body as he watched a portal rip open from beneath his feet, blackness seeping through the cracks. The blackness clung to him, sticky and permanent to his skin, and he was overwhelmed.

Realization smacked him square in the face. He knew what was happening, and there was nowhere to run.

Marshall had never feared this outcome, because he had never thought he would outlive his full demon mother, him being half human and all, but afflicted with vampirism he had forgotten about the possibility…

Chaos was what ruled his demon blood. His ancestry harnessed, controlled, and devoured chaos. And now that his mother had been slain, by whatever means, that chaos was unleashed.

"Oh Glob…" He uttered as he felt the energy burst forth and force itself into the little half demon shell of Marshall Lee's body. He screamed as he felt that absolute dark power take control and contort his form. He mutated to transform into a monstrous beast of proportions he had never accomplished before. His psyche was lost to the swirling chaos as it beat down all rational thought inciting fury, grief, lust, and mania instead.

Panicked, and overcome with power, Marshall Lee the Monster tore through Aaa in a killing spree never before seen by vampires for hundreds of years.

He was unrecognizably horrid, and when finally, the chaos had exhausted itself, Marshall Ran. He ran away from everything he loved and cared about, carrying within him that awful power which threatened to burst forth at any sign of mental weakness.

Nobody had known where he went. No one seemed to care. Rumors about the monster grew rampant, and it attacked several more times in the coming two years. All the while Marshall hid and wrestled with the chaos thrust upon him, succumbing to it every once in a while. Wishing he was dead.

Two years later, in the TreeDome:

"Ugh!" Moaned Fionna as she slapped down her sword on the kitchen table. Cake moved her meatloaf aside just in time and eyed Fionna curiously.

"What's the matter Fionna, date with the Muscle Prince not go so well?" She asked.

"No! It was awful! Cake, I really think I just am not meant to be in a relationship."

"Aw, sugar don't say that…" Cake said patting her sister on the back. "You just gotta find the right guy… or gal I won't judge."

"It's just that everyone seems to run away from me. Like, two weeks into things it's always the same. I fight some monster, or get real tough with something and they always say I'm too much or some crap! I at least thought Muscle Prince would understand… but he just drinks protein shakes and rubs his arms in oil all day."

"Ew…" Said Cake, cutting her a slice of meatloaf. "Well, you'll never be alone Fi. You know I'm always there for you!" Fionna looked at Cake and smiled sympathetically, but it wasn't the same. Cake had kids, a soul mate, a life away from her. Fionna wanted the same thing. To blaze her own trail, but no one would blaze it with her.

"Thanks, Cake." Fionna said taking a bite of the meatloaf. At least Cake had been home tonight, usually when the sun set she would-

"Well, I think it's time for me and Mono's alooooone time." She said, picking up her plate and making her way to the kitchen.

"I think I'm gonna go take a walk tonight, don't wait up, okay?" Fionna responded, meekly trying to suck some motherly attention from her sister.

"Okay, baby! Be safe!" Cake said already packing up her sleepover things from the living room. Fionna felt a pair of fuzzy, stretched lips kiss her on the head, and the door closed as Cake left the house. Fionna sighed at her half-eaten meatloaf. Cake hadn't really lived at the Tree Dome for quite some time, but it was nice for her to come by to make Fionna dinner, or have video game nights with her. Cake was a good sister, but Fionna wanted a life of her own. She wanted a relationship, someone to share things with. But no one would. Was there something the matter with her? Everyone always praised how much they liked and admired her, but then why didn't anyone want to get deeper?

With PG it was the age thing (regardless if it wasn't an issue anymore),

With Flame Prince it was the whole 'where would we live' thing,

Hunter Wizard was all 'the strong live alone'.

And Marshall Lee, well he just straight up disappeared after his mom died. Probably ruling the Nightosphere or something.

Ah, Marshall. She missed him exponentially every day. She didn't realize how much time she spent with the dude until he disappeared one day. She had spent most of her time with him in fact, and when he vanished, Fionna saw that no one had time for her. Not Cake, nor Gumball, nor Simone, or any other of the Aaa residents.

She had tried dating. Vigorously, for the past two years, but to no avail. She felt nothing, or very little towards most dudes and it was clear that they felt the same way about her. It didn't exactly help being the heroine of Aaa, either. She wasn't feminine or charming like the princesses of the other kingdoms, and it never failed to scare away guys every time she drew a sword or arrow.

Feeling especially bummed out, tonight, Fionna took her usual walk in the woods to mull over her thoughts. It had become a habit. Most nights she'd come to the forest past the little grove of fig trees and over the big boulder to sit under the thunderous sound of the waterfall. It always provided great zen and feel good vibes for her to sort out her mind junk. Fionna stripped in the darkness of the night to slip into the water. Her hair had grown exceptionally long, and it pooled around her as she treaded deeper. The thoughts still buzzed inside of her head, so she pulled herself underwater feeling the muteness of the rushing water in earholes. She stayed underwater, holding her breath as long as she could, before she bursting back to the surface.

Little did she know that she was being watched.

"Hey, there." Came a voice from the woods.

Fionna spun to see a forest witch at the edge of the woods, and sank into the water to cover herself.

"Hey…" She responded.

"I like your hair." The witch replied, coming closer into the water. "Can I have it?"

"My hair? What, like a chop of it?"

"No, all of it. Scalp too. I want it to grow longer!" The crazy witch said, reaching to touch a strand of Fionna's golden hair.

"Yeah, I don't think I can do that." Fionna said, pulling her hair out of the grasp of the witch. The witch cackled.

"Oh, I'm sorry. Did I ask? Let me try again. Give me your hair!"

The forest burst to life around her, trees swayed, flowers shivered, and the weeds of the rivers began to claw at her legs. Vines and roots burst from the riverbed to wrap around Fionna's ankles, and the more she tried to kick them away, the more entangled she became. Suddenly, she was pulled underwater. Fionna had forgotten to take a breath, and already she was fighting for air. She opened her eyes to see the knobby, wooden hands of the witch coming towards her to take hold of her hair. With a sharp pull, her hair began ripping from her scalp, follicles plucking off of her dome one at a time against the force of those branched claws. Fionna screamed underwater, releasing the last bit of air she held on to. Fionna had nothing, she was naked as the day she boom boomed on that leaf, and the roots held her firmly to the riverbed. Desperatly, Fionna felt along the floor of the river for a rock, a stick, anything to fight back with then something hard and sure formed inside her hand. It was the familiar shape of the hilt of a sword. Aiming blindly, she forced the sword upwards and it made contact. The vines on her ankles slacked and she kicked to the surface to gulp in air. The sword was stuck inside the witch.

"Ouch." She said cattily. "That really hurt." The witch pulled the sword from her wooden body, but no sooner did she draw it that the sword burst into light, and the witch straight up disappeared. The sword clattered to the ground, seemingly useless once again.

Fionna stood in the water, catching her breath and felt along the nape of her neck which smarted and came back red on her fingers. That witch was really going to scalp her alive!

"What is the matter with people?!" Fionna moaned before she got out of the water to pick up the sword to examine it.

'The Banisher of Evil' it said on the hilt. Hm, cool, but where did it come from? Curiously, Fionna looked into the water to see if there was a skeleton or other discarded battle gear with it. But there was nothing. How strange. She squeezed the hilt. Fionna could have sworn that it materialized right in her hand. It made her dorky sword-girl nerves tingle. Awesome! She would have to get this looked at tomorrow. Already she was fantasizing it all shined up at her side.

"Banisher of Evil…" She repeated, tucking it into the elastic of her underthings as she began walking home, almost forgetting her previous loneliness.
