AN: This is my first fanfic, and just let me have a try ^^. The updates won't be too frequent, as I am up to posting a chapter every 2 days. Review if you like this, as it will be much appreciated. Chapter 1 will be posted tomorrow.

Further Notice: I do not own anything of Adventure Time, as it belongs to Pendleton Ward.

Prologue:

Three adventurers sat in a small room in the Candy Castle of Ooo. Their sidekicks were next to them, nervously waiting for anything to happen. Jake stared at Cake in disbelief, and after a few seconds they moved their eyes to look at Jolly the Chinchilla. Of course Jolly was uncomfortable with that.
Strangely, the three bravest, strongest and loudest people from the three lands didn't say a word. Finn was playing with his fingers, Fionna was scratching the table with her nails, and Mike was playing with his little clay man. They didn't dare to look at each other. Prince Gumball and Bonnibel came into the room through a small door at the side of the room, and they both disrupted the awkward silence.
Gumball took a seat, whilst Princess remained standing. "Young heroes. I am sure all of you are confused about whole of this situation, so I arranged the meeting between the main people from Ooo, Aaa and Eee", Princess Bubblegum looked at Peppermint Butler, and he opened the big door. Marceline, Marshall Lee, Lady Rainicorn, Wondy, Ice King and even Lumpy Space Princess entered the room, and formed a circle around the table of heroes. They all came in quietly, and they didn't talk at all, including LSP, which meant that probably everyone was shocked.
PB scanned the crowd, and stretched her arm out to make a presenting gesture towards Mike, "People, I know every one of you is confused with the situation. Our hero from Eee has probably all the answers you need, and he will be able to tell you the story fully."
Mike's throat went dry. He didn't like to speak to crowds. He was confused about where to start the story, "Where should I start?"
Prince Gumball saw the scared boy and he wanted to help him to give all the answers, "Right from the beginning. The place in time all of this started."
"But it'll take hours to tell. I mean, don't kings and queens have to rule the kingdoms?" He asked and looked at Wonder Princess.
Princess Bubblegum gave him a kind smile, "Oh, we have got all the time to spare. Go on."
Mike searched for the appropriate beginning of the situation. When he thought that one event caused it, he remembered that another one caused it too. He browsed the links and sequence of the events until he stopped at one event. The place where everything will be described fully and clearly understood and, finally, the situation will be explained to everyone, "So, right. One day I was with Jolly, cleaning the bushes from trash trolls..."
