Chapter1: Another adventure?

(A/N): this story will have a few changes from the preiview. There will also be reaction command moments so give a suggestion for a reaction command in one of your reviews.

~A sound soul, rests within a rockin bod and an Amadeus mind~

The screen fades in to a white quiet beach. The splashing of waves were the only sound that filled the endless land. Aside from the ocean there was an endless beach that was almost completely covered in swords. All swords ranging from different shape to size to weight and width.

The only life on that lonely beach was 13 – year old Finn the human. He wasn't sure how he got there or why he was there, but all he could see was the swords and the endless sea.

"Where am i..? is this a dream? How did I even get here?" he continued to ask himself as he continued to search his surroundings. "Hello? Is anybody here? Anyone?" Finn asked in hopes of a response. But all the response he got was the echo of his voice. "ah man, i knew I shouldn't have been eating finn cakes past bed time, Jake says it messes with my brain. Oh well, at least there's a lot of cool looking swords here.

Not being able to do anything else Finn decided to look around the beach of weapons. His eyes began gazing at each sword he passed by. Each one looking even more cool then the last. He felt like a kid in a candy store for adventurers. The downside was that there were no monsters to use the sword on. He could have skinned himself a new hat. But as he continued to go farther across the planes of swords, what seemed to be his shadow had started to grow as he went past each sword. As Finn continued to walk across the plane he had soon saw a sword that was all too familiar to him.

It was a gold battle worn sword that was chipped in most places and scratches in others complete with a black handle and a red jewel at the bottom. "Hey, I remember this one. This is, the sword I began my adventure with. Good old scarlet." Finn said as he picked the sword up from the ground. As he looked at it's blade he could remember the times he went through with the sword from fighting the ice king to saving princesses.

"Wait, but how is it here?"

Finn had flashed back to princess bubblegum's science barbecue where he was using the glasses of nerdecon to make himself super smart.

"Last time I remember.. my sword turned 4 dimensional and I destroyed the black hole. But my sword was gone along with the black hole. So why is it here now?" he wondered as he continued to stare into the blade.

"You sure ask a lot of questions for a kid don't you?" said a mysterious voice.

"Huh? Who's there? Who said that?" "I did dummy, I'm like right in front of you." The voice said rudely. "Huh? Right in front of me? What do you mean?" Finn asked still confused. "Oh for the love of.. look down genius." Said the voice causing Finn to look down. But all he saw was his shadow wich for some strange reason had eyes. "Huh, are you the one talking to me?"

"Who else would be talking to ya. Last time I checked we aren't exactly in a public place." Said the shadow. "wait, my shadow is talking to me, this must be a dream." Said Finn. "Wake up bolt for brains, this is your subconscious, not a dream. and if were here, that means something big is going to happen and it's going to need more then just one hero. "Wait, so I'm going on another adventure? Awesome! But wait, just who are you? And what do you mean another hero?

But the shadow only sighed in annoyance. "It doesn't seem like I'm going to get anywhere if we go on like this, I might as well get out of this stiff form, it's way to much pressure on my body. The shadow said as it had slowly disappeared. "What?" Finn was confused when his shadow disappeared. But soon a bright light had took place in front of him. The light was so bright it had blinded him. When the light cleared the sword Finn had in his hand was gone. "What the.. what happened to my sword? Huh?" Finn was surprised that now standing before him was a little girl with blonde hair that reached her ankles. She wore a white and yellow tank top that seemed to be torn all over with a red jewel in the middle wearing black sandals. The little girl had yawned as she stretched her arms.

"Ahh, that's much better, I never thought I got to stretch my muscles ever again." "Huh? Who.. are you? And how did you get here?" Finn asked still confused. "are you seriously that dense or did you forget? My name is scarlet." The girl said.

"Wait scarlet?" "Yeah, in other words the sword you've been treating badly for the past years. And I didn't really appreciate the way you abandoned me last time. "Wait a minute, you were.. the sword that sword? But, but how is that even possible?" Finn asked still confused. "well technically I'm a demon weapon, but I've been stuck in weapon form for almost a thousand years now. it's about time I finally got some freedom once in a while. "Freedom? What do you mean?" he asked still confused.

"Ok, listen slowly I cause I'm only going to explain this once. First of all I'm not a little girl. i really can't explain why my body took this form after all those years. Maybe that poor excuse for a man had something to do with this. "What man are you talking about? Was he your current owner?" Finn asked receiving a pinch on the check from the girl.

"Listen here buddy, we were partners, he doesn't own me or vice versa got it?!" scarlet asked annoyed. "Ouch, ok ok you guys were partners I get it!"

"Good" scarlet said as she let go of Finn's cheeks. "So who was this man anyway?" scarlet's face turned to one of worry as she was trying to explain.

"oh sorry, I probably shouldn't have asked." Finn said trying to apologize. "No it's ok, my partner was someone you would want to meet."

"Really? He must be pretty cool then. Who is he?" Finn asked with a smile.

"He was your father." Scarlet said bluntly. The smile on Finn's face changed into a look of shock and despair. "W-what?" was the only words that could escape his mouth at the moment. "Your father was my previous owner."

"Wait, do you mean Joshua?" "No dummy I mean your human father. Don't you find it a little weird calling a dog your father?" asked scarlet.

"I had a human father? But, I don't even remember having a human father.. or mother now that I think of it. Finn said holding back a tear from his eye.

"Oh right, you were left on that little leaf when you were a baby so I shouldn't imagine that you'd have any memory of the guy.

"What, how do you know…? "He had told me stories when we went into battle together. But rather then explain it to you your father left something for you. Your real father. In a few seconds a blue boy style box had appeared in the girls hands. "He told me to give this to you sometime before he left."

Scarlet had gave the box to finn. " I think you can read these in something called a holo viewer. He said you knew what it meant. "Memories of my real father.. is in this box?" "Well it's time for me to go. I'm wasting enough energy as it is." "Wait.. I still have more questions."

"Oh don't worry, we'll meet again real soon. Just find me in the cotton candy forest. Oh and you should probably prepare yourself. a life changing adventure is waiting for you. but I'm sure what ever comes your way you can handle it.

"How are you so sure? I don't even know where I'm suppose to start. I'm not sure if I even can do it. I never knew I had human parents until now. how are you so sure?" asked Finn

"how can I tell? It's obvious silly. Your soul's all the proof I need." Scarlet said with a smile. "My… soul?" Finn asked still confused. "Mhm, you don't know it but your soul is a bright and strong one. The song that it sings whenever your on your adventures sings a song that gives you tons of courage.

"My soul huh?" finn asked as he looked down at the box. "Ok, I must be going now, but before I go there's one thing I must tell you.' said scarlet as her left arm transformed in to a golden blade. She had pointed the blade at finn's forehead. "If you let your soul waver in the face of danger, you'll die." She said as she ran the blade through. At that moment Finn had awakened back in his and Jake's tree house in the land of ooh. When he awoke he was still in his sleeping bag on his bed. He now had serious bed hair.

"Oh glob. Am I imagining things? That seemed way to real to be a dream." Finn said as he reached for his bed sheets. But as he lifted his bed sheets from the bed, he had saw the blue box the girl had gave him.

"Maybe because It wasn't a dream." Finn said as he tried to open the box. but he had soon discovered that it was locked. " ah dingle, of course it would be locked. How am I suppose to open this thing? But then Finn had remembered what the little girl had said. "We'll meet again.. just find me lying somewhere in the cotton candy forest.

"How did she know about that place? Has she been to ooh before? And just how does this box has anything to do with my real parents?" a million more questions ran through the young heroes mind. but his thinking was interrupted by the call of his best friend Jake the dog.

"Yo dude you up yet? We gotta meet flame princess in the cotton candy forest today man.

"Oh Dang, I almost forgot we were suppose to go into that new dungeon I found yesterday." Finn thought to himself.

"Uh I'll be down in a minute man you go on ahead!" said finn. "Ok, but don't go whining if all the good dungeon monsters are pulverized before you get there!" Finn had looked out the window as he saw his friend running from the front door heading for the candy kingdom. Finn had grabbed the box and put it in his backpack. "Real father huh? I wondered what happened to him."

"Finn had put on his backpack and his trademark hat. Before he climbed down he had grabbed his demon blood sword from his bed side and headed down.

"Finn obtained box of memories"

"A few minutes later finn met up with his best friend jake the dog and his girlfriend flame princess. "Yo guys I'm here."

"There you are finn. I thought you were attacked by king worm again." Flame princess said jokingly. "Nah, me and Jake kicked that worm's can a long time ago. I just overslept." Finn said as he held his hands behind his back.

"Finn, are you okay? You don't sound as hyper as usual." Said flame princess.

"Huh? Oh no worries I'm fine. I just had a weird dream. it's all good." Finn tried to keep a believable smile on his face. But it was obvious to Fp that something was bothering him. But she decided to not pry at the moment.

"So, where's the secret entrance again?" asked flame princess.

"It's a secret door we found under the candy castle. We saw peppermint butler come in here once. We don't even think princess bubblegum knows about this place." Said Jake as he began sniffing trees.

"uh guys, don't you think no one else knows about this place is maybe because people aren't suppose to be here?" fp asked as Jake was looking under a rock.

"Nah, if it was something we couldn't Handel peppermint butler or princess bubblegum would have told us so. now where's that switch I found. As Jake and flame princess continued looking, Finn had noticed something shining out from some of the bushes. "Huh? Could that be…." Finn had searched past the pink bushes and saw the golden sword he thought he lost.

"Just like she said, in the cotton candy forest. But why would it.. or she be here?" Finn asked as he picked up the sword from the ground. But as soon as he did there was a sound of something clicking. Soon after there was a low rumbling coming from the ground. "Uh, why is the ground shaking?" flame princess asked as she began wobbling. She soon lost her balance and landed on Finn who was nearby. Without a flame shield protecting him of course Finn was in pain but he made a good job of not showing it. "Are you ok?" he asked.

"Uh yeah I'll be fine." She said blushing slightly. "Guys! Check this out!" jake said as he pointed to the ground wich had now revealed a secret staircase. As soon as the last of the dirt and sand cleared the rumbling had stopped.

"Looks like we found the entrance." Jake said as he watched the entrance appear. By this time Finn's shirt was almost burned through the middle by now and flame princess just now noticed. "O-Oh no, Finn I'm sorry, I forgot you weren't wearing a flame shield." Fp said apologizing. "Ah don't worry about it I didn't even feel anything." Finn said lying through his teeth. He wanted to yelp in pain for being in contact for so long but he didn't want to hurt her feelings so he decided to grin and bear it.

"So what do you think's down there anyway?" asked Flame princess. "Don't know, but we won't find out standing around here. Let's go." Said Jake as he transformed into a cheetah and went on ahead. "Hey wait for us!" flame princess called as she and Finn followed behind.

-Finn obtained the Scarlet- the scarlet was added to Finn's inventory

.Underneath the candy castle.

"As they walked down the dark staircase, aside from the rotting vegetation and the multiple bugs crawling around, the walls seemed to have ancient drawings of what seemed to be monsters. Though the drawings were so old and covered in dust that they seemed to be unreadable at the time. "Is dungeons like this suppose to give you the creeps?" asked flame princess.

"Usually if peppermint butlers involved something is bound to give you the creeps." Said Jake. Finn found himself staring at the walls of the different drawings of monsters. Just looking at them only made Finn more and more excited to find out just what's waiting for them at the bottom of the dungeon.

"when they reached the bottom floor they had walked through a nearby hallway arriving to what seemed to be a tombstone. "What's this thing?" asked Finn. "It seems like it's a giant tombstone. But it doesn't say who died." Said Flame princess. "Hmm, fp, could you give me a little light?" Finn asked as he moved closer to the stone. "Sure." Flame princess had burned a little bit brighter so Finn could read the writing on the tombstone.

"Warning to all those who venture here. If you seek for treasure you will find none. If you seek for glory you will find none. If you seek for knowledge you will find none. All you will fine beyond this tomb is a corrupted soul doomed to roam this kingdom for eternity. The only thing able to keep this soul at bay is either one of great dark presence or one of a presence that is pure. Only one of these can either bind this evil or bind it and force it into slumber for a set amount of time.

Beyond this tomb you will only find the souls of humans being that has been corrupted to the very core. Weither the soul was tainted by acts of murder or betrayal, no one really knows. There for if your soul is not one of great light or great darkness you MUST turn back now. less you wish your life to meet an early end. And that's where it stops."

"dang man, what do you think could be so evil to be buried all the way down here. And why under the candy kingdom?" Asked Jake.

"I don't know, but whatever's beyond it must be something very important. I mean come on they wouldn't honestly set something like this up without some big prize at the end. So I say we move forward!" Finn shouted. But he had soon stopped as the gold sword on his back started to move on it's own. "Finn, what's up with your sword man?" asked Jake as he watched the blade rise from Finn's back on it's own.

"What the what? what's going on now?" the sword had stuck itself within the tombstone. The words on the tombstone had began growing brightly for a few seconds then had stopped. A few moments boulders had started crumbling causing another tremor. Soon after another hallway was revealed. But the feel was different as a dark ominous feeling had filled the room. "Woah, tell me I'm not the one who just felt that." said Jake. Flame princess seemed to be the only one not phased by the presence. It actually felt familiar to her.

"What do you think we should do guys…guys?" when Fp looked to the side Finn and Jake were already charging through the hall way. "ADVENTURE!" both of them screamed as they disappeared in the dark hallway. "Guys slow down! You don't know what could be down there!" Flame princess called as she had followed them riding a stream of fire. As the heroes continued to move down the hallway lanterns on the wall started to spontaneously set ablaze even though flame princess was all the light they would need. The hallway seemed endless. But after some period of time they had finally reached an end. They had came up to a large circular room that seemed like a coliseum. There were stone marbles everywhere that seemed to be stained with dry blood.

There were multiple piles of bones everywhere. Some bones even still had bits of flesh left on it that were decaying for a decade. The site was an absolute horror. "Dang…just….dang." was all Finn could say at the moment.

"Dude.. it's a complete horror show down here." Said Jake. "What could have done this?" Flame princess asked looking around. As they were still watching what was left of the merciless destruction, Finn's scarlet had began glowing again. The sword had seemed to synchronize with a nearby pedestal in the middle of the room.

"Hey Finn, your sword is doing that glowing thing again." Said Jake.

"Finn had draw the sword gold sword from his back and held it in front of him. Soon a large circle of light had appeared around the pedestal. Then for some reason Finn and Jake suddenly fell to their knees. They felt like there very souls were jumping at the moment. "Guys, what's going on?" asked a concerned flame princess. "I don't know, my body feels so heavy all of a sudden. What did that thing do to us?" Finn and Jake tried to think of what just happened, but there was no time as the ground under the pedestal began to crumble. As the pedestal began to disappear a low growl could be heard coming from underneath. "Dude what was that?" as soon as the last of the ground around the pedestal had disappeared, the low growl they heard from before had grew louder and had started muttering soul over and over again.

"soul….soul….soul…" the voice said with a dark tone. "Get ready guys, something's coming." Said Finn as he drew his scarlet and demon blood sword.

Jake had turned his left hand into a spiked fist and flame princess was ready to burn what ever came out of the mysterious hole on sight. Soon the growling had completely stopped. For a few minutes there was a tense building silence that filled the room. "Ah what, did that thing give up already?" Jake had walked up closer to the now bottomless hole and tried to peek to see if anything was there.

"Jake be careful dude!" warned Finn. "Ah relax what's goanna happen?" Jake said as he peered down the hole. But his question was soon answered as a dark green claw had sprouted from the hole nearly taking off Jake's nose if he was just a few inches closer. Jake was nearly paralyzed that it took him awhile to notice that the claw was about to try to grab him.

"JAKE GET OUT OF THERE MAN! Finn screamed. "Huh?" Jake finally came back to his senses and saw the mysterious claw about to attack him.

Jake had stretched out of the way just in time avoid the attack. as the claw had clinged to the ground, a head had began to arise out of the ground. Out from it esd s face that was patched up by dirty worn out bandages covering the entire face except a glaring red eye. she had long flowing black hair and had the figure of a woman at the top and the body of a serpent. The giant woman's lower body was covered in black and red scales and at the end of the tail was a red mark that looked like a eye opening sideways. Her arms were as skinny as her bones and her claws were a dark green coloring that seemed to have the same dry blood as the blood on the walls.

"Holy flip man! Now that's a monster!" said jake gazing at the giant serpant lady.

"S-S-Souls…." The woman had hissed as she looked down at the three."

"S-S-S-Souls… delicious souls, offer your souls to me mortals…." She said looking hungrily at the three heroes. "No way ya bag of bones! These souls are staying in their bods! So prepare to go right back in the hole you crawled out of!" shouted Finn. "Insolence… you will offer your souls to me. I still need 3 more human souls left… then I will be nearly complete. I must feast..

I MUST FEAST ON SOULSSSS. The serpent woman had lead out a huge screech that was so loud it filled the abandoned hallways.

Information: Defeat the Serpentress

The snake woman had brought down her claw striking down one of the nearby pillars. "Look out!" Finn shouted as they had ran avoiding the falling pillar. But this had gave the beast a chance to grab flame princess.

"Agh, let me go!" "FP!" Finn shouted as he saw his girlfriend getting lifted up from the ground. But that didn't last long as just touching her had burned the snake woman's hand causing her to scream in pain. FP used her fire to slower her descent to the ground making a safe landing. "Hey you ok?" asked Finn.

"Yeah I'm fine, guess I was to hot to handle for her." Flame princess said jokingly. "Hey dude, let's use our combo move on this ugly she beast. "Oh yeah let's kick it homie." Finn said before he gave a high five to his best friend and charged at the beast with Jake following behind him.

The serpentress let out a screech again as she struck both her claws into the ground summoning ancient black and red snakes coming from the ground.

"OH glob man, snakes!" said jake. "FP, give us some cover!" shouted Finn as he continued to run. Flame princess had nodded and had moved ahead of Finn and Jake. "SCATTER FIRE!" FP said as she released two whips of fire from her hands. The two whips of fire made contact with two separate heads of the many snakes. As soon as one snake caught on fire the rest of the piles off snakes. The snakes soon all burned simultaneously as Finn and Jake jumped over the remaining piles of the snakes. "Ok, I'll go left you go right." Said Finn as he went around the left side of the beast and Jake went around the right. The woman tried to decide which one she should follow as they went around. She decided to follow Jake as he was running towards the wall.

"Ya can't catch me ya old hag!" jake said as he continued to run. "the woman only responded by opening her mouth and began charging a purple ball of electricity. 'Uh Finn.. a little back up here." Jake said as he saw the oncoming attack.

The snake woman had aimed the attack at Jake and had fired. The blast had began picking up speed as it started to spark as it came closer to Jake.

Press ^ repedeatley.

Jake had turned around and had turned his left ear into a shield blocking the attack. he was able to force the attack into the air again as he turned his left arm into a baseball bat. "Batter up!" jake said as he struck the ball of energy back at the beast. Though the serpentress had slithered to the right avoiding her own attack letting hit the ceiling causing some rubble to come down on her. As she tried to shield herself from the falling debris falling on her, she didn't see Finn jump off one of the near by pillars.

"Finn had jumped in the air and did a summersault before he had pointed both swords down at the monster and let out a tarzan yell.

But the serpentress had saw finn coming and attempted to use her free hand to knock him towards the wall.

PRESS X TO USE SWORD FALL COMAND.

Finn had flipped and dodged her claw and then tossed his gold sword in to the left eye of the serpentress. As it writhed in pain this gave finn the perfect opening as he quickly landed on the serpentress's head and stabbed the second sword right through her skull causing black blood to come gushing out.

It had let out a scream louder then usual as it was shaking left to right trying to get finn of it's head.

"Yo finn, fp's about to char that thing, you better get out of there now dude!" said jake as he was running away from the moving beast."

"Oh driz." Said finn as he began trying to pull both of his swords from the monster. But as he did, he had noticed the beast had raised both of her hands and was preparing to smash finn into a hero pancake.

PRESS O TO USE FIRE BLOW.

Finn had managed to pull his two swords from the cranium of the beast as he quickly jumped off and landed on jake who was still running from the monster as flame princess had carghed up a large fireball Kamehameha style.

Finn and jake managed to get at a safe distance before flame princess had launched her attack. the fireball seemed to be the same size of the monsters head. As soon as the attack made contact, the she beast's head had set ablaze. Soon the whole body of the monster began to burn as well as it's head.

As they watched the monster burn finn's scarlet had began glowing again.

"Huh, what is it this time. h-hey" shouted finn as his golden sword had pulled back towards the monster.

"Finn?! what are you doing?" jake asked as he looked back at the burning monstrosity. "I DON"T KNOW!" shouted finn as he was dragged towards the monster.

The sword had soon stopped and pulled finn into the air. As soon as he was high enough the sword had started to glow a light blue energy and so did finn.

"What the flip, what's going on now?" asked finn as he could feel power surging through his body. but he had little time to think as the sword had quickly made a slashing motion releasing a large light blue energy wave slicing the beast in half.

"Whoa…" Jake and Fp said as they watched finn annihilate the beast. As the serpentress let out a few last dying screams, her body had disappeared into black dust. And what was left behind was a small white orb with a blue flame around it.

"Finn the human leveled up!

Finn is now level 2

"Increased Hp gauge.

"Finn has learned skill Spirit Cutter"

Jake the dog has leveled up

Jake the dog is now level 2.

"Jake's Hp increases.

Jake's strength increases.

Jake can now use dog pound!

"Flame princess has leveled up!

"Flame princess is now level2

Flame princess Hp increases.

Flame princess can now use inferno blast!

Finn had landed on his feet and gazed at the mysterious object.

"Dude, what is that?" asked jake.

"I don't know. Fp, do you have any idea?" asked Finn.

Flame princess only shook her head.

"I'm sorry, I don't know either. Maybe it's a type of flame since it looks like it's got a little flame at the top.

"Maybe we should take it back to princess bubblegum for testing. Maybe she knows what this thing is." Said Finn.

He took a small jar out of his backpack and placed the weird glowing item inside.

"Hey Finn, look there," said Jake as he pointed to a shining item on the floor that was covered in mucus and saliva.

"What is it?" asked Finn

Jake had picked up the item and on further inspection it was an oddly shaped key with a skull on the top of it.

"It's a key man." Said Jake.

Finn had took the key and inspected it. The key seemed like it would make a perfect fit for the box he had retrieved in his dream.

"What do you think it opens?" asked Flame princess.

"I think I may have an idea, but let's get out of here first. Never know what else could be lurking around this place. Let's go to Pb and see if she knows anything about this." Said finn.

"Um, Finn? you sure that's a good idea?" asked Jake.

"What do you mean?"

"Well, we both know that Pb has trouble with believing magical stuff and all that junk. If she see's that she'll probably spend weeks trying to come up with a logical soulution. I think we should go see Marceline about this one." Said jake.

"That's funny, first time I heard you suggest going to marcy's place. I thought you were scared of her." Said finn.

"That was a long time ago man. I builded up a resistance. Now nothing scares me." Said jake. But he got scared when flame princess pinched him while he wasn't looking making the dog scream and jump.

Finn and Fp couldn't help but laugh at the magical dog.

"Come on, let's head over to marcy's place and see if she can identify this biz." Said finn as he tucked the key away in his pocket.

"Good. Now can we get out of here? This place is giving me the creeps." Said Jake as he and the others walked out.

End of chapter1

"So Finn, Jake, and flame princess find a mysterious object after their encounter with an unknown demon. But little do they know the item their carrying is more then just a mere item you receive from any dungeon.

Will princess bubblegum be able to help find out what the mysterious item is? Or will they need help from a familiar but unwanted face to figure it out? Find out next time in chapter 2."
