Disclamer: I don't own Adventure Time with Finn and Jake

I wished I did though. Anyway, hey guys! Its my first time on here so I would enjoy CONSTRUCTIVE criticism and see what you guys really think of it. Compliments wouldn't be too bad either haha.

This is the first Chapter.

Finn and Jake are at the Tree House, trying to figure out what they should do today. Jake makes two everything burritos, figuring its probably not best to figure things out on an empty stomach. He hands Finn his burrito and joins him at the table.

Finn says " This is bad man, I can't think of anything to go adventure the math out of…" as he takes a huge bite out of his everything burrito.

Jake nods in agreement and says " Maybe you should finish your burrito first and then try to think of something. Your brain's probably crazy locked up right now, behind a whole bunch of shiny golden doors and my everything burrito is the key! "

Finn says "But there is only ONE everything burrito, so wouldn't it open only one door?"

Jake retorts "But it's an EVERYTHING burrito, there's a lot of different things in there that could open all of those doors!"

Finn says " OHHHHH, alright. I get it now… sorta."

Finn and Jake remained silent so they could finish their everything burritos. Finn felt better after eating but still couldn't think of anything for him and Jake to do. They spat (literally) where they could go but whatever one would input, the other didn't feel like doing. Finn decided to go spend some time with Flame Princess and maybe he would find something along the way.

"Jake! Im gonna go hang with Flame Princess for a little while. Maybe I'll find something for us to explore." Finn shouted to Jake who was upstairs.

Jake said "Alright. Remember: NO TIER 15."

"I still don't know what you're talking about" Finn called back as he left.

On the way to Flame Princess house, Finn starts thinking.

" Maybe I should just hang with Flame Princess today… Jake could go hang out with Lady, spend some time with his unborn babies. Then again, after those little guys are born, me and Jake won't be able to adventure as much. He'll be too busy taking care of his kids, keeping them safe. I wonder how Jake would be as a father?" Then a flashback of how Jake was supposed to be helping teach Goliad how to be a good ruler was brought to Finn's laughed to himself, "Not good with other people's kids but maybe with his own. Man, that was a crazy day. PB was so tired, made me feel bad.

…Bubblegum…!"

He bumped into Flame Princess at that point, toppling them both over until they lay beside each other on the soft grass by her house.

"Hey, Finn," said Flame Princess in a giggle, "You looked like you were deep in thought. What were you thinking about?"

Finn said " Oh nothing really, just Jake and his unborn babies. Wondering how it'll be like after they are born."

"Are you worried you won't get to spend a lot of time with him after they are born?" replied Flame Princess curiously.

"Just a little, but I'll be their uncle and I plan on being the most top notch blooby uncle ever." said Finn a little proud.

Flame Princess sighed "I wished I could have had that kind of uncle. I never really got to know mine. He was Flame King before but he had a terrible accident with a river when visiting a nearby kingdom hoping to spur trade between ours and theirs. That's when my dad became Flame King."

Another flashback of the time Jake and Finn had gone to the Fire Kingdom to retrieve Flame Princess's candles and the conversation Finn had with her father came to mind. " So wait… you extinguished their dad?" said Finn wanting justification. "Mmhmm" replied the Fire King nonchalantly. "And everyone is evil here?" questioned Finn. "Mmhmm … All evil." Flame King replied after doing an acrobatic jump in the air, landing on his feet. Finn then asked out of extreme curiosity "Then is Flame Princess evil or maybe chaotic neutral?" Flame King quickly replied "She's evil." … Finn thought about what he wanted to ask, hesitated and then asked "Is that what he told you?"

Flame Princess nonchalantly said "Well thats what we filled out on the police report. But I know what happen. My dad pushed my uncle into the river after he sent his security away on a break. "

Finn replied "Oh….. and you're okay with that?"

Flame Princess sighed " I guess. I just wanted to get to know my uncle better though. Maybe he could have been the kind of uncle that you're going to be to Jake's babies. But other than that, things just happen. And sometimes they're meant to happen. If that didn't happen, I wouldn't be Flame Princess and we probably wouldn't have met so…"

Finn looked downcast and said "Oh….that makes sense, I guess." Silence enveloped the two as neither could think of what to say to the other. They looked around at the environment but did not dare look at each other as that would just make the moment even more awkward. After a few moments, Finn asked Flame Princess to walk with him and she agreed. They didn't decide on a particular direction, so Finn decided to leave a trail so they wouldn't get lost on the way back. He took out a variety of things from his backpack that he was sure no one would take and left them in places he would recognize as they were walking. Then they were off. While they walked they talked about things they enjoyed doing, being sure not to bring up Flame Princess's family again. In fact they flipped the switch in which they started talking about Finn's family

Flame Princess asked " So Jake is really your brother?"

Finn replied " Yea, we're homie bros for life!" Flame Princess looked confused for a moment. She remained silent for a few moments, trying to decide whether it would be a good idea to ask her next question.

She asked " But Jake is a dog, and you're not, so how can you be brothers?"

Finn replied "Well short story is Jake's parents found baby-me in the woods and adopted me. They've been the only parents I have ever known so you know that's just how it is for me." Finn looked off into the distance content, reminiscent of his childhood memories. Flame Princess smiled at him. She picked up a rock, kissed it and put it against his cheek. He turned to her and smiled.

"So if Jake's mom and dad aren't really your parents, where did you come from then?" Flame Princess asked prying for more.

"Jake says I came from a cabbage, that's probably not right. I thought I met another human who could've helped me figure out our beginning, Susan, but now I am not so sure if she is or not. Other than that, I don't really know." Finn said starting to think again. He looked around and stared in front of him. He and Flame Princess were standing in front of the gates of a place he had never seen before. Finn and Flame Princess walked around the perimeter of the new tall walled place.

"This place looks kinda old. Like no one has been here in a long time. Me and Jake are going to be its first visitors in a while." Finn said excited because he finally found something for him and Jake to do today. Flame Princess was apprehensive " You guys are really going to go in there? Why?" Finn replied somewhat surprised " Uh… for the fun of finding something new and being one of the greatest adventurers alive?..."

"Ummm… it looks a little creepy but okay, I let you get to that but be safe. Will you walk me home?" asked Flame Princess not wanting to be around the new found ruins any longer. "Yea I'll take you home, kinda have to since your house will be me and Jake's starting point." They shared a laugh and at that were on the way back to Flame Princess's house

"Soooo, I'll see you tomorrow?" inquired Flame Princess as she and Finn reached her front door. " Of course, Flame Princess." replied Finn as he walked back towards the tree house.

"Jake! Jake! Jake! I know what we can do today!" Finn exclaimed as he entered the house. " I found a place that we've never been over by, it looks really old and run down, like no one has been there for years and years!"

Jake replied "That sounds awesome, dude. But maybe we should look it up at the Candy Kingdom library first. Make sure its not some place that'll blow us up to bits and pieces?"

Finn reluctantly replied " Aw, why can't we just blindly adventure into places like we usually do? Looking stuff up before we go takes the fun and suspense out of exploring."

"Hey man, I'm gonna be father soon, and I don't want Lady to have to explain to my hybrid children why I'm not there. I want to be there to explain why I'm not there!" said Jake. Finn stared at him completely dumfounded "What?" . " ...uh…um…hmm… that didn't come out quite right…. But you know what I mean!" said Jake determined to change Finn's mind. Finn seceded from his position with a fine. The two decided that until they found out a little more info about the new found area, they weren't going to pack anything. So off they went to the Candy Kingdom

As soon as Finn and Jake reached Candy Kingdom, they soon realized that in their hurry, they had forgotten to eat. They decided to eat candy garbage for lunch. After most of the garbage had been picked up around Candy Kingdom, Finn and Jake sat on the side of the road to eat. While eating, Finn sees a tall pink figure pass by and immediately knows who it is.

"Finn, Jake… what brings you guys in today?" says Princess Bubblegum as cheerful as ever to see her two knights roaming her streets. "Oh, well Finn found these ruins when he was hanging with….." Jake pauses for a second after seeing PB frown slightly and Finn look in the other direction "anyhow we're going to use your library to see if we can find anything about it. Make sure that whoever use to live there wasn't crazy paranoid and left a bunch of booby-traps to explode in our faces." Jake finishes with a mouthful of candy.

Princess Bubblegum replies "Oh how wonderful! Well I wish you guys good luck on your quest, do bring a souvenir for me please. I have some experiments to be getting back to. I just came out here to check up on my citizens. See ya soon." PB walks towards a corridor and vanishes from sight.

Jake wonders "Yo Finn, what was that all about?" Finn says nothing and finishes his candy garbage. He then motions for them to go to the library, again without a word. Jake takes Finn's silence on the matter as a cue to drop it. They continue up the stairs without a word, but Jake continually stares at Finn oddly, trying to figure out what could possibly be going on between him and Princess Bubblegum.

In the library, Finn and Jake had found a map dating back possibly 100 years after the Mushroom War. Finn identified an area that looked to be where Flame Princess's house would be and followed along the path he made from memory to the now ruins. Unfortunately, there was nothing but field in that area of the map. Jake suggested to look at a newer map out of reason that the ruins might not have been there back then in that time.

They continued to look at newer and newer maps until they found the latest edition. Obviously that wouldn't showcase the ruins so they went in the other direction, looking at older and older maps until they found one issued in the year the Mushroom War happened. It was somewhat worn, tearing in some places and fading in others. In spite of that, it was still useful. Finn again figured where Flame Princess's house would now be and traced his memory path, he found a peculiar area in place where the now ruins are. It had no name, but he knew it was the place.

"Jake, this is it. It's gotta be. Maybe it was some kind of new kingdom or something but somehow disappeared before the war." The gears of making possible reasons the kingdom disappeared started working in Finn's mind. It filled him with excitement, one he had never known before. Jake still wanted to know a little more about the kingdom, but as he rifled through more maps and extremely old documents that could have some indication of the peculiar kingdom's people, there was no luck.

"I don't know about going to check this place out Finn. We don't even know what it's called. We have no info about it except where it is and that it somehow disappeared." said Jake. He was really stuck in the middle emotions. "I mean the adventurer part of me really wants to check the math out of these ruins. But the almost-daddy part of me says it might not be a great idea."

Finn starts thinking. Then he says "Alright but your adventurer side is full right?" Jake nods. Finn then says "And your daddy side is only almost full right?" Jake nods again. "So until your daddy side is completely full, let your adventurer make most of the decisions, while letting your daddy side make some decisions. Let adventurer Jake take this one though." Jake nodded in agreement " That makes sense."

They decided that the information they had already gotten was probably all they were going to get, so they went back to the tree house and packed up what they might need. After doing so they sped towards Flame Princess's house and started their journey to the ruins.

Along the way, Finn and Jake were talking about all those books Jake has in the house by Jay T Dogzone. "But why would you have them in the house if their just mess u up books?" Finn inquired. Jake quickly replied "Because... they're funny to read." "Come one man, tell me the real reason. We're homies." Finn says calmly and warmly. "I keep them in the house because….I…kinda…wrote them." Jake, feeling ashamed, looked down knowing what Finn's reaction would be. Finn exclaimed "WHAT?! AND YOU NEVER TOLD ME!" Jake waited for Finn to calm down a little before he explained. He sighed "I wrote those before I really knew about love. Before I hooked-up with Lady. See, when you're just dancing with some babes, and you do that a lot, you think you know them and what they want. But when you meet someone who makes the bu-bumps in your heart go crazy, those rules you made up, don't really apply anymore. So really I keep them because it reminds me of how none of my rules for babes apply to Lady. Makes me remember why she's my one and only."

Finn amazed "Wow, that does make sense. But what do you do when more than one person….!" At that moment, they bumped into the gates of the Finn-found ruins. Jake examined the perimeter with amazement. He knew he made the right choice siding with his adventurer. "We'll get to your question later, right now, let's go check this place out. The outside already looks awesome, imagine what the inside would look like!" Just as they were to go in, Finn asked "Hey Jake, shouldn't we name it something? Then we can go back to Candy library and fill in what we found about it." " Yea, man, what you think it should be? You're the one who found it, you should name it." Jake replied anxious as ever to get inside. Finn thought about it and then said "Well since we don't know how it got here and even how it disappeared, there's a lot of mystery involved with it. So maybe just Mystery…. Mystery Kingdom." "Sounds mysterious and suspensy, I like it." Jake replied hyped up. And so without knowing what might be beyond those gates, Finn and Jake entered, the suspense-filled, evasive, Mystery Kingdom.

Mysterious, right? Haha. Well that's the beginning. Funny thing is I know WHAT and HOW I want the end to be but I only know WHAT I want the middle to be! I haven't completely figured it out yet. It'll be filled with drama for sure, I'm just not sure which route I want to go about it.

Anyway, thanks to whoever reads this! I hope you like it and I'll have the next chapter up soon!
