Adventure Time: Parallel meetings (T)

Adventure Time: Parallel meetings
Fionna and Cake meets Finn and Jake! Explore the world when Aaa meets Ooo, the two kingdoms kicks in an ally, or rivalry, some fall in love and others war!

The plot explained...
It all begins when Finn searched trough an old abandoned library, some even say it's from before the great mushroom war, one that was taken place a 1000 years ago, a horrid and scary war that extinct pretty much every human on the planet, but there is one, possibly a few more, no one really knows, but his name is Finn, and his friend, a magical dog, Jake, that still explores into this, trying to figure out why the war began... Well, at least he is the only HUMAN who would search for such an explanation, others would back away, are there more humans in Ooo, or, possibly, Aaa, nobody knows... BUT, Finn decides that, as he discovered the library, found behind veins of the jungle, behind trees and a forest, to search trough it, to see if he can find any information on it, and then he does... and... well... he finds something of great value, a book, a very old book, indeed, it might of have been there since before the war, it was very dusty, but he found it, and looked into it, and... it explained of a kingdom... and a human girl, Fionna, who's best friend is a cat, rather than a dog... but... Finn recognizes this... Fionna and Cake, they are from Ice Kings fanfic! The evil ice wizard, but, where they really real? Well, he would never know by just standing there, so he read on, and it explained of a mirror, and this mirror, if one has this book, and the mirror is placed in the same exact area in both of the worlds, one can enter into the other world. Finn thought about it, and he spoke to Jake about it, well, appears that he would try to find said mirror, he was curious about this, and... another human... could it really be... The mirror was behind allot of terrain, in a forbidden cavern far away form the library, but Finn really wanted to know about this, and Jake was pretty curious about this too... Marceline, partial demon and a trusty vampire, also very naughty and playful, being a prankster of all kind, was also curious on this idea, she thought it could be dangerous, but she was willing to try anything that would involve danger, seeing as it probably was worth it in the end... Once they arrived in the cave, Finn checked the mirror, and, indeed, it opened a portal, as the three entered unto it, they were greeted with a similar kingdom, but was it really the one explained in the book? Yes... yes it was... and they would soon figure out allot more about this kingdom... but why did Ice King write about it, guess it wasn't a fanfic after all... seems like it all was really...

A story for his mission: as a 7 year old he was in the carnival with his family. it was crowded and there was pushing everywhere. he was separated from his family in the crowd. they pushed him until he reached a tent. standing in front of the tent was a tall man with a white case that had a swirl of black in the middle. he captured him and put him in the case with great speed and power. in the case he met god (or glob in adventure time). the god gave him a pure white sword that always glowed and could only cut evil. he used the sword to break out but doing so caused such a blast that he split into two people. one that was mostly good with a touch of evil sealed in his left eye. the other mostly evil with a touch of good sealed on his right eye. the good him was weaker but much smarter and had the heaven sword that had gifted him special abilities but the sealed evil bribed him with power of its own. the bead was opposite in strength and knowledge but the devil gave him 2 pure evil red swords and ruthlessness with abilities of its own but the good could reach him if necessary. with no knowledge of his power the evil him left the good him to fight alone to the tall man. but he was no mach so swore to kill the man and purify himself from his other self. even though his other self would try to kill him right after the purification.

the back-story isn't that great but it explains his reason. I don't know if it counts that the demon possesses his body for species. i don't know if i should have put the story in the bio but i wasn't sure :P. I hope the story was good enough for you it was actually a dream i had once and it was so amazing it has been 7 years and i still haven't forgotten it. we are supposed to post here right?
