Chapter 1: A New but Old world is found.

Note: I don't own adventure time and if I owned Tron do you think Kevin would have died NO he wouldn't have. And if the grammar bugs you don't read.

Finn and Jack had arrived at their destination courtesy of Finn trying to win the heart of Princess Bubblegum. After his vain attempt PB gave them the job of taking a report at the excavation site where a pre Mushroom War building had been discovered and help in the dig, because the princess was too busy at the time to do so herself.

A full side of the building had been uncovered by the time they arrived at the site. After taking a quick report of how the dig was going(20 pages, light reading only for Princess Bubblegum)Finn told Jake to take the report back to PB while stayed behind and help with the dig wanting to see what the building looked like out of the ground. Jake proceeded to grow long legs and take off with the report stuffed in his fat folds while Finn began helping to uncover the old building which had gradually been taking a more defined shape.

It was nearly midnight by the time the building was completely uncovered. The giant neon sign "Flynn's" was hanging from the front of the building. Jake and PB had arrived back by that time. They were amazed at the site before them. The trio (Finn, Jake and PB) then entered the building preparing each other for anything. PB looked around with a scientist's eye of curiosity examining everything.

She noted the plastic covering every object in the room, the power boxes attached to the wall next to the door and the floor mat with the word "Flynn's" written on it. 'How strange who was this "Flynn" that had his name on what seemed like everything' she thought to herself. She proceeded to open the larger of the two boxes on the wall to find a series of switches with words written next to each of them she decided to flip the 'sign' switch and quickly walked outside to look at the sign that now illuminated the night. Heading back in she decides to flip the switches that stated 'music' and 'games'. While PB had been examining everything and learning about them, Finn and Jake had been pulling all the plastic off of the machines.

When PB turned on the power for the games they lite up and music began to play out of them for the first time in more than 1000 years. The music coming from the speakers on the walls now playing loudly and deafening all three of them. PB quickly flipped the 'music' switch back off again to the relief of all of them.

Now staring wide eyed at all of the now active games they began trying to figure out how to play the games. Finn began to think that the 25cent sign on the games matched a large round metal object they had found a bunch of a few months ago it even looked like it would fit in the slot so going on this guess he pulled a bunch out quarters out of Jake's fat and put one in.

The game (a.k.a Pac Man) immediately responded with a series of sounds, a flash on the screen and the game started. After a few minutes of playing Finn finally was defeated by Pinky, giving up he and Jake began to play all the other games. PB noticed this she asked for some quarters to try the game. They gave her a few quarters which she promptly used to play the game; she then beat in a matter of hours. By the time they made it to the game at the back of the room it was almost sun up. A large neon sign hung over this game saying 'Tron'.

Down to the last few quarters they put one in only to have it be spit out onto the floor. Bending down to pick it up Finn noticed grooves in the floor curious about it he and Jake moved the machine on its hidden hinges to find a large metal behind it. Finn opened the door to let Jake walk through and look around seeing nothing but a set of stairs he came back into the door frame and gave them the go ahead.

They entered and began to descend down the stairs to find yet another door this one wooden. Turning the handle slowly Finn opened the door. Inside were a lot of things but all over everything was a very sizable amount of dust. There was a couch that probably hadn't been sat on in forever. Many pictures of a man and a boy were covering the walls. A diagram of what had been so boldly capped as 'The Grid' was also pinned to the wall showing a series of sectors with notes next to every other one.

There was a laser standing in the center of the room. The final noticeable object was a table with ever counting numbers moving across a built in touch-screen with a fancy leather arm-chair pulled up to it. Interested by this PB cleaned the seat, sat down and wiped the dust away from the screen.

At her touch the computer woke from its long sleep mode. Curious she began to attempt to learn what this computer had inside. First she typed the most basic command 'Whoami'. The computer responded 'Flynn'. 'Yet another thing this Flynn owns' she privately thought to herself. Finn and Jake both gathered on each side of her to see her work on the computer.

After a few tries to login she succeed in getting in to the system. She then pulled up the last known operations hoping to see what had been the last thing used and saw 'Laser Control'. She looked back at the object in the center of the room. 'So I know what you are, but now I want to know what you do'. Determined to get to the bottom of this she activated it, taking note of the laser behind them turning on.

A box flashed onto the screen 'activate laser yes/no'. With a look back she typed 'yes' and pressed 'enter'. The laser fired at the three of them. After a second of blinding light the room was empty.

Note: I will be making references to Doctor Who and other such television shows. This was originally a crossover but I decided to place it in one section to have it seen more.
