Hi all! This is my first fan fiction and I am not particularly experienced in writing stories. I had always been a huge fan of Adventure Time and the franchise has always held a special place in my heart. I really look forward to everyone's feedback on my work and there will be more chapters to come! I had been pondering on whether or not to write this fic for a while and finally decided that I should go for it.

This story will mostly be about Finn, but other characters will be given representation as well. For clarification, This fan fiction will be taking place about a year and a half after the final season of the show since the prologue doesn't exactly state it. I will include perspective shifts between chapters or in the middle of chapters when necessary in order to encompass the full story. While I may be set on the given format for my writing style, I may change it depending on how things go as I continue writing.

Any and all constructive criticism is welcome and even wanted since I am inexperienced with story writing. Chapter 1 may not come out until after New Years since I will be flying around the country visiting family, but I hope that this prologue will help give you all an idea of what you will be diving into. Thank you again for reading my story and I hope you all will get plenty of enjoyment out of it as I continue to release chapters!

I do not own 'Adventure Time'.


Prologue: Forgotten Omens

He couldn't see a thing, feel a thing, hear a thing….. Darkness was present all around him and he couldn't even make out his own form even if he had tried looking hard enough. He knew he was conscious and that his thoughts were present, wondering where he was and how he had gotten here. Realization dawned upon his consciousness.

"This is a dream, ya it's gotta be."

But, why was everything so quiet? Why was there nothing to fill his senses? No physical forms, no sounds, no smell, just the emptiness of whatever void he was floating in. Attempting to speak or make noise was futile as well. Every time the human would try to emit something from his own vocal cords, he would only be met with the ever present silence that had surrounded his being or lack thereof.

"Most donked up dream yet. No ogres or bandit peeps with magic wands. No treasure or labyrinth like dungeons to crawl. What the hay is up with this?"

The human had thought to himself. It was true, this dream was not the typical thing that he would usually conjure in his mind every time he went to sleep and he was so used to them being lucid. This dream was different….. Unsettlingly different. He understood he was dreaming and yet he couldn't control anything, influence anything, or even expect anything. He wasn't even in control of his own emotions.

Something primal and as old as living beings themselves creeped into his mind, his very soul. It was fear….. fear so powerful that he wanted to break down, run away to anything, anyone, anywhere.

"Wake up wake up wake up wake up wake up. Glob…. please wake up!"

He began to feel suffocated. Nothing was in his control. No matter how much he commanded his mind to let him wake up from this void prison, nothing would happen. It felt as if he was going to be stuck there for eternity or at least until some outside force would wake him up. Just as if his mind began to race faster and faster, something happened.

"FWOOOM"

What he could only make out as a giant ball of green fire, burst into existence, piercing the park veil of his dreamscape and uncovering everything with its ghastly green light, emitting from its inferno. Almost as if a blindfold had been removed from him, things began to materialize around the human, giving him a sense of direction, physical presence, sight, smell, you name it. Even being able to see himself now, his physical self, the human known as Finn desperately tried to take in his surroundings. He was standing upon a hill in the grasslands of Ooo. Finn would have welcomed the sight in all of its familiarity, blanketing him in a comfort which he had been desperately lacking when his earlier senses were so restricted. But… he was met with no such comfort or familiarity. 'Death' was the only word that anyone could use to describe what he was seeing. Instead of the lush green hills, buzzing bees, and blue sky that he had been so acquainted with, he was met with not a single blade of green grass. The surface which he stood upon barely resembled anything that used to be alive, other than a few tufts of dead and shriveled plant life. The only other thing giving the surface any character other than the dead grass was all of the scorch marks, scarring the land.

There were no buzzing bees or singing birds. The howling wind, the last breath of a hollow world was the only thing that filled his ears. The ever so vibrant blue sky and bright sun that he would always bask under was no longer present either, only providing him an overshadowing curtain of a hopeless gray and ash filled atmosphere in which the clouds and ash couldn't even be told apart.

"I will always come back….. to take away everything you hold dear, to extinguish all life. I AM INEVITABLE."

What could only be described as the feeling of his heart giving way to the halt of its beat and the sensation of every hair follicle upon the back of his neck standing overtook Finn. Every instinct told him to run as fast as he could without looking back at the source of the dreadful voice that echoed behind him. He had spent his entire life thus far battling monsters and slaying evil, forging his bravery in the most worthy of trials and tribulations and yet this voice, this horrid voice that crept behind him and seeped into his ears like poison had him absolutely terrified.

Hesitantly, the hero braced himself and turned slowly towards the source of the voice. When he had finally faced in the direction of the deathly noise, he was once again met with that same ghastly green inferno that had fueled this nightmare. The green flame was no longer in its original form however. The sight of an all too recognizable foe, one that he had wished would never make presence again stood before him. The flaming skeletal visage adorned with horns, standing at the other end of the hill, looming over him like a spire of mind numbing fear, stared into Finn's eyes, reaching into his soul and strangling it.

As Finn soaked in the sight of his worst enemy, the feeling of terror never left him but, it was beginning to be accompanied by another emotion. It was anger, hatred even. After all of the pain, all of the suffering, and all of the effort that went into putting an end to this accursed entity, here it was standing before him, taunting him as if spitting in the face of everything he had fought for.

"No…. NO! How are you here!? I stopped you! I destroyed you! Why can't you just stay gone!?"

He was barely able to choke out his words, but his determination along with the ever growing flame of anger within him kept his feet firmly planted upon the ground as he defiantly stood up to the burning manifestation of destruction. Finn had done too much and had fought tirelessly to protect the world he lived in and the friends that resided upon it to give into the gnawing sensation fear now. Something within the malicious flame began to rumble forth, shaking the ground which Finn stood upon. It was laughter… A laughter wicked and corrupt enough to send a shiver down the young human's spine and cause a cold sweat to dampen the collar of his shirt.

"HAHAHAHAHAHAHAHAHAHAHAHAHA!"

The green inferno ceased laughing and paused for a moment. The next thing Finn knew, the horrific figure began walking towards him, causing the dreamlike plane behind it to dematerialize and fade away as it burned up like paper from the green flames, returning to nothingness. When the looming monstrosity came within a few feet of the human who had defied its existence and purpose, it stopped and spoke again.

"You've stopped nothing. All you have ever done was delay the imminent destruction of life upon this rock no….. this universe. Just as you are a perpetual force woven into the fabric of time, so am I. I will not stop, I will not cease until all life is extinguished. It is what I exist for. No meddling will stop my march to snuff out creation. Not even you, child."

"Screw you and screw your bullcrud doomsday monologue! If you're gonna keep coming back then I'll just keep beating your sorry hams! It's as simple as that!"

Finn wasn't even confident in his proclamation, but no matter what, he knew that he had no choice to back down. It was all or nothing when it came to the entity that stood before him, threatening everything in existence. Finn continued to stare down the ghastly being, just as it did the same to him. The feelings of fear led to feelings of determination and resolve as that burning sensation from his emotions grew stronger and stronger until it felt like it would burn through him.

As the green flames continued to eat away at the physical plane around them, something began to halt their encroaching heat. It was a different heat, something that began to envelop the human as his emotions grew stronger. The next thing he could tell, green was met by blue as what seemed to be cosmic flames colliding with each other filled the scene, their opposing natures violently wrestling to dominate the other. The burning sensation within Finn only grew stronger; however, it did not bring pain. Rather, it brought him a sense of strength. The blue inferno began to dance around the human as he pushed back against the advancing destruction. Dead tufts of grass around his feet began to turn green once again and the soil below him started to regain its nutrient rich hues. Frustration rumbled from the destructive entity as the advance of its flames staggered.

"Prepare yourself, child. You and I shall meet again and when we do, I shall revel atop the mountains made from the bones of you and everyone else."

Before Finn could throw in another snarky comeback or even lift his fist to strike the flaming green visage across the face, his vision was overtaken by a blinding light which an ethereal figure emerging from said light. A giant owl, golden in color, adorned in shimmering feathers, spread its mighty wings and cawed with a deafening urgency.


Finn's eyes shot open as he lunged himself upward from his bed, breathing heavily. He quickly looked around him in a panic, only to realize shortly after that he had awoken from his nightmare. As he looked back upon himself, he noticed that his hand was shaking and that his body was covered in a sheen of sweat. It wasn't often that something like a dream would cause him to wake up in such a violent manner.

His eyes diverted from himself and back to the room he had been sleeping in. The first thing Finn noticed was that the entire room was in disarray. A chest of trinkets and adventuring gear had been knocked over, The bedroom window which the morning sun had shined through was all but shattered, books that were lying upon shelves were scattered across the floor, and a sword which had sat upon a plaque on the wall above his bed was now planted into the wooden surface of his nightstand. The most prominent thing in the room however, was the giant crack in the stone floor which reached past the carpet and halfway up the wall where the door was.

"Was there an earthquake or something?"

It was the only explanation that Finn could formulate in his mind. The combination of his nightmare and violent awakening didn't make it any easier to think due to the 'haze' that his head was in. He pulled the covers off of himself and swung his legs over the ledge of the bed. Just as his feet landed upon the carpeted floor, he noticed something out of the corner of his eye. BMO could be seen, hiding behind one of the legs of the dresser that sat across the room. The little guy was shaking like he had seen a ghost as he nervously peered from behind the wooden pillar.

"Hey BMO….. are you ok? What's going on with you buddy?"

Finn could only surmise that whatever had caused his room to fall apart the way it did was what scared BMO. He stood up from his bed and began to walk over to BMO, kneeling down close to the little robot with a look of concern.

"Did we get hit by an earthquake? Is that what's got you all rattled?"

BMO shook his head or more so his whole body due to the lack of a neck. The small game bot hesitantly stepped out from behind the wooden leg of the dresser and looked up at Finn with a face that would melt just about anyone's heart.

"There was no earthquake, Finn. Football and I saw everything!"

"Well, what exactly did happen?"

Finn asked, raising an eyebrow as he brushed his bedridden hair out of his face. BMO began to frantically shake his arms as if he was about to tell the wildest story.

"It was your invisible arm! It flew out and moved everything! It broke my favorite mirror that I like to use to talk with Football!"

BMO exclaimed as digital tears began to pour down his screen. Finn had trouble trying to figure out what exactly BMO was getting at. He always knew that the little dude had a vivid imagination but this was new when it came to BMO's "recountings". First it was Football, his imaginary friend. Next it was his supposed detective case on Finn's missing sock. Now there are invisible appendages destroying the house according to the bot.

"Haha! You certainly are imaginative BMO."

Finn said cheerfully as he patted BMO on the head before standing up and looking around at all the damage in the room again. BMO in return let out a frustrated growl as he continued to wave his little arms.

"I'm not making it up! You grew an invisible arm thingy and tore up the room!"

"Whatever you say, little buddy. Look I'll get you a new mirror to talk to Football through alright?"

A frustrated sigh escaped from the little robot's speakers. He crossed his small arms and began storming out of the bedroom. Finn watched confused as BMO stomped away. Before doing anything else, he decided that cleaning up this mysterious mess and damage as best he could came first. Starting with the books, Finn placed them back on the shelf, one at a time. As he slid the last book back into place, he paused as his hand still rested on the worn material which made up the spine of the book.

"Haha invisible arm."

Finn looked down at the stump where his arm used to be. He wasn't wearing his prosthetic at the moment since he usually didn't like sleeping with it on. Painful memories of his father began to make their way into the back of his mind. He shook the thoughts from his head and remembered the positives as well. Memories of Breezy giving him a sense of hope again after he had been through the wringer. The presence of sweat upon his body from when he had violently awoken was the next thing he observed. It must have been a crazy dream…..

"Wait, what did I dream about? Now that I think about it, I can't seem to remember a glob damn thing about it."

Finn pursed his lips for a moment in thought and then shrugged as he walked over to the sword lodged into his night stand. He gripped the hilt of the sword with his only available hand and placed his foot on the side of the night stand for leverage. After a strong tug, he freed the sword from the wood and stumbled back a bit. After regaining his balance, he looked at the blade of the sword, seeing himself in its reflection.

"Guess this one has gone into the vault too."
