I do not own Adventure Time! Characters belong to Pendleton Ward!

This is my first fanfic so far and I'll try to upload a new chapter as fast as I can. 'cause I'm not a native speaker it might take a bit of time, though.

Please tell me the mistakes I've made, I'll go ahead and correct them then.

Have fun :3

I swept up my deadly red sword made of deamon blood, sparkling as the sunlight touched its blade. The giant hand rushing towards me stopped insantly, three fingers vanished in a river of greenish liquid leaving the creature roaring and screeching.

As quick as a rabbit I hid behind a boulder and observed my enemy, waiting for my next chance to strike. I didn't know what the monster was called, though. It was huge, covered in hard grey skin and walking on unnatural long legs. Where you'd look for normal fingers was a hand which ended in long, sharp claws, its finger nails colored black. On top of the skinny body was a slim human-like head although its bones were lined sharp against the skin on its cheeks and the nearly bald occiput was only covered with a few white flicks of hair. Instead of eyes there were two dull panes of glass, revealing the creature was blind.

However, its senses were at least as sharp as mine and I crouched deeper to the cold and stony ground. We were in a mountains cave with half of the roof vanished where the sun broke through, making the shadows dance and quiver with every singe move.

A movement in the corner of my eyes caught my attention since my best friend and brother was hiding there, peeking through a small gap in the rock. Jake moved his lips in a silent whisper, trying to tell something to me, his human companion.

„What?" , I breathed, hardly making a sound. The dog rolled his huge eyes in annoyance, laid his paw on his chest and then on his ears.

I can hear your heart beat.

My blood froze in horror as I felt it beating hard against my chest, trying to break through it. A silent urge to jump out of my shelter and end this right away made my joints itch.

Trying to order my thoughts and recall our plans how to attack, I didn't recognize how quiet it had fallen again, that the roaring had stopped. What either meant it was already dead (which was quite unlikely) or...

I swallowed hard and dared a quick look from behind the boulder. Icy grey eyes met my gaze, broke through my mental barrier right into my soul, making me shiver in blank horror and disgust. Somehting deep down in me froze and shattered, I couldn't move although I was aware of the fact the monster had spotted me due to my terribly loud heartbeat.

Once again I cursed myself for being human since all the inhabitants of Ooo were so much stronger, quicker, more dangerous and just better in everything than me. I was so weak, gave myself away by only living.

Tears of protest and anger began to sparkle in the corners of my eyes, made my sight blurred and dull. I could already feel an icy breath on my face but couldn't see anything. Everything went cold and grey, lifeless and terrybly slow. Visions of my past tried to overwhelm me. Pictures of happyness and sadness, hatred and love came back into my view. Joshua and Margaret, my brothers, Princess Bubblegumm and all the times she hurt me, the forest, dark and scary while I laid there, abandoned by my real parents. Left alone, unloved.

I...don't...want to...remember! , I screamed but no words left my mouth. I'm...living right now!

It was no use. I could smell the monsters dirty breath, could feel its sharp claws dig into my own soft hand. I was half frozen now, with every second my view got darker and darker and my protest weaker. Why did I fight again? It didn't matter anymore.

Mh...maybe dieing isn't all that bad...

The weight got off me and for a second I thought I was dead, then suddenly all my senses came back, heat flowed back into my body like a river in an empty pool. My gaze cleared again so I could see how the monsters eyes right in front of me widened in dismay and shock before the yellow string around its throat tightened again and its body went limp. Lifeless it laid there on the stony ground with sunlight dancing on its chest, making it look peaceful.

„Finn, buddy? Are you alright?" Jakes face was only inces away from mine, his voice heavy with worry. „Yeah." , I croaked, trying to sound cheerful. „Back off dude, you look gay."

The dogs laughter filled the air around us and the hand he'd used to kill the monster streched back to its normal lenght and pulled me to my feet. „Anyways, thanks for saving me."

He just declined and backed off a few meters, giving me room to walk. Trying to hide my still shivering fingers I rubbed off the dust from my clothes and put my beloved white hat back on since it was about to fall off.

„How'd you manage to kill it? I thought we could only win by attacking a couple of times, comfusing and weakening it slowly."

„Nah, that's for fighting it. You know, these creatures have more brains and strength than it looks like. But this one was dirstracted by...uhh...what exaclty did it do to you?" , Jake dared to ask. He knew I didn't like talking about being vulnerable.

„Not much." , I murmured and was about to leave the cave when a bright light exploded right beside me. Blinded by the sudden flash, I had to blink a couple of times, trying to make something out.

When it faded, the monsters body had disappeared. Instead of the ugly creature there was a white pool, shimmering and quivering like water. Still, it was shining in a bright, warm light.

„Woah." , Jake breathed beside me. „What the heck is this?"

„Dunno." , I whsipered, stunned by the amazing view. „But Jake"

„Huh?"

„I have the strange feeling it's...Adventure Time!"

„Here we are! Chapter 37, Portals. According to very few witnesses, portals are opened if the spatial and time sphere gets torn apart. This can only be achieved if the virtual lock is damaged, due to its keepers death. The number of people time-travelling is little, no one ever managed to get back to their own time, though. Scientists claim..."

Jakes voice trailed of, 'cause I got bored again since I was playing with another books pages, drawing invisible signs on its cover. I hated the library! There was a real portal waiting for mme, another time to be adventured! And Jake had dragged me to the library to read books first.

„Why did we come here again?" , I asked uninterested while I was searching through the book shelves to meet Paper Pete again. Dust tickled in my nose and made md sneeze, which earned me another stern Ssshhh! from the Turtle Princess.

„To read, silly. Before we just jump through that portal-thing, we should learn about the dangers and consequences! What if it explodes and we're lost between time and space forever? Or we don't get back? I don't want to live in some stinky parallel universe! I'm getting father, remember?"

„How could I possibly forget that? You keep reminding me each day again if I complain about the amount of time you spend with Lady..." , I started to yell, revealing everything I felt the last days, letting my anger out of me like the air out of an balloon. „It's like you don't care about me anymore! I tried to understand, I really did! But I'm lost without you Jake, being the last of my race isn't easy...I just feel like I'm in the wrong place..." ,I whined, a singe tear rolling down my cheek. My head bowed in grief, I began to make my way back to the tree house to take a shower, eat and rest before I would cross that portal the next morning. I was determined to do it, here in Ooo was nothing to be missed. I might not belong in this other land beyond the portal, but I didn't belong here either. At least that's what everyone made me think the last months.

„Finn, wait." , Jake spoke softly, stretching his arms to stop me, his brother, from leaving. „You know how much you mean to me, buddy. I love you as much as I love Lady, only in another way. The last years I was always at your side since you needed me most, but now Lady is pregnant. Now she is the one who needs me most, no matter how much I'd like to spend more time with you, Finn. With each day the day of birth gets nearer and with children to care for I have to stop acting like one on my own. I don't want to hurt you and I will cross this portal with you, but not without being sure how to come back. Give me a few more hours to read and plan our trip, therefore we can leave tomorrow at sunhigh. Deal?" , he asked, his voice full of worry and regret. Looking in the dark, watery eyes of my friend, this was the moment I had wished the floor would open and bring me right to the Nightosphere. I had been too selfish to recognize how much I had accused Jake for something he wasn't to be blamed for.

„Yeah, deal. I guess I'll go anyway...ya know, taking a shower and stuff..." , I murmured and added in my thoughts: Sorry, bro.

„Fine with me. I'll buy the needed stuff afterwards and eat at Lady's. By the way, there are spaghetti left over from yesterday in the fridge, so you can eat them for dinner. See ya tomorrow morning then."

„Mhm, see ya." Hands in my pockets I left, ready to spend another night alone.

The stars sent their bright rays through the window in my bedroom, lighted my lonly dreams as Iwas twisting and turning uncomfortably in my sleeping bag.

„Finn? Finn, wake up. You look like you're stuck in a spiders web, moving like that." , a voice whispered. It was familiar, although he didn't imagine him to be here.

„Jake? I thought you'd sleep at Ladys'..." , I yawned, cuddling deeper into my warm bed.

„Na man. I decided you needed me most now." Warmth flooded through my veins as I got the dogs words. He chose me over Lady, his pregnant girlfriend. „Thanks, Jake."

„No probs. Get back to sleep, the next few days will have less of it."

„Jake?"

„Hu?"

„Joshua and Mararet loved me, right? I mean, like I was their real son."

„Of course the did, buddy! Forget the issue with dads dungeon? He even told you that!"

„I know but...why did my human parents leave me? What was wrong with me?" , I sobbed. This question had troubled me for years now but I never managed to ask it.

„Nothing, Finn, you were a perfekt brother. Sometimes we just have to do the wrong thing in order to achieve the right. Don't think about it. You're a hero, Finn, and some day you will be able to see that.

„Thanks, Jake. Good night."

„Night, Finn."

„Food? Tent? My sword?"

„Check." , Jake said in and annoyed tone, rolling his eyes. „As I told you before, I've got everything!"

„Clothes? A few extra hats?"

„Yes! Finn, listen! I-"

„Mums' lullaby music box? I know you can't sleep without it."

„Yes." , Jake growled, blushing slightly. „Can we leave now? Yesterday it was you who wanted to leave right away."

„I just want to make sure my little puppy has everything he needs." , I mocked and rushed out of the house, laughing.

„Oh wait, you little brat." , the dog snarled playfully, chasing me over the meadows of the Gras Lands. The sun was nearly at its highest point, warmed the air around us to a beautiful summers day. Birds were singing in the trees like they'd tell us soon to come back.

Arriving at the mountains edge in the cave where we'd fought this time-keeper, we rested for a moment, trying to catch breath.

„Ready?" , I panted, already walking towards the shining portal, looking in its white wavy surface.

„The last one is a stinky Goblin!" , Jake yelled, jumped and vanished in the light. With a smile on my lips I followed, eager to adventure wherever the portal would take me.

Bright white light exploded around me, took my sight. Everything whirled and twisted, cold and warmth came and left in a heartbeat.

Then everything was suddenly still again, the light vanished in thousands of sparks as I opened my eyes to a whole new world.

Next chapter Finn will finally meet Fiona! Oh my glob :DD

Tell me if you didn't get a thing and I will try to correct it. Also, my writing style is way better in German, so tell me also if I should just give up and leave this story.

Review plz? :)
