Sora, Fang, Vincent, and Professor Von Drake entered the Professor's lab underneath the mansion. The lab was essentially a large grey stone chamber with walls covered with a variety of different pieces of lab equipment. There was hardly a blank wall in the room except for a large empty space over a drawing table with a series of half-finished blueprints scattered all over it. On one whole wall was a computer system with a keyboard and monitor similar to the one in Ansem's Study in Radiant Garden. Connected to it was a device that looked like a giant tanning bed. As soon as Sora entered the lab, a strange gun attached to a mechanical arm swung down and aimed itself at Sora with an electrical hum to it.

"Whoa!" Sora yelped but the Professor pressed a button on a remote control and deactivated the gun, causing it to rise up towards the ceiling and move over towards the center of the room.

"Sorry about that. Just a little security system I have installed in case we have intruders." Professor Von Drake said with a chuckle as he walked over to the "tanning bed" and opened the lid, revealing it to have a flat, black surface, on the inside on both the lid and bottom.

"What's this?" Sora asked curiously.

"It's a scanner. Most people use machines like this, albeit small ones, and scan pictures or documents onto their computers. This scanner allows me to scan anything onto my computer. This is what we are going to use to scan this object of yours. So where is it?" Professor Von Drake asked as Sora reached into his pocket and pulled out Namine's dress. It had been folded up so it would fit in his pocket.

"Uh, please tell me that's not yours." Fang said, earning a glare from Sora.

"It's Namine's actually. Aqua and Si'Lea found it and gave it to me." Sora replied as he handed Professor Von Drake the dress. The professor placed it on the scanner and shut the lid. Almost instantly the machine hummed to life, a soft green neon-like glow appearing along between the gaps in the lid. The computer monitor then turned on, lines of data running over the screen as it scanned the dress.

"Hmm…most interesting." Professor Von Drake said as he looked at the data carefully.

"What is it Professor?" Sora asked curiously.

"Why I never knew you could have that percentage of wool mixed with polyester. I imagine it would be very comfortable." The professor laughed as Sora and Fang both groaned.

"Oye. Do you think you could shelve the comedy for a while, wise man? Master Sora's in a hurry here." Fang said as Professor Von Drake nodded with a smile and turned back to the machine, continuing to read the data. Suddenly the monitor started flashing red and a sign that read "Hacker Alert!" started flashing on the screen. The scanner started to crackle with electricity and the green lights on the scanner turned red instantly.

"Uh-oh! What does that mean?" Sora asked as he started looking around.

"It means LETS GET THE HECK OUTTA HERE!" Fang shouted as she grabbed Sora by the arm, who grabbed the Professor by the arm as well before getting dragged out of the lab at high speed with Vincent in hot pursuit. They moved just in time as the security gun started firing a single steady stream of red hot energy. They didn't even bother looking at where it was aiming and slammed the door behind them. They heard the alarm sounding for a few more moments along with the gun as it continued firing. Finally it all went silent, save for a single intermittent beep from the computer. They slowly opened the door and saw that the lab was flooded with dense smoke. Prof. Von Drake quickly whipped out a remote control and pressed a button. Instantly a fan turned on and sucked the smoke out of the room in seconds. They slowly entered and saw the gun, disabled and powered down, drooping down on its robotic arm towards the floor. Professor Von Drake quickly moved over to the scanner and threw open the lid.

"Goodness gracious! The DRESS is GONE!" he exclaimed. Sure enough there was nothing, not even smoke rising from the scanner.

"What? You mean Namine's dress is destroyed?" Sora asked in shock.

"No…it's as if it completely evaporated into thin air!" Professor Von Drake exclaimed as he spun around. He was about to say something else but he spotted something behind the others that made him freeze with his eyes wide and his mouth hanging open.

"What is it?" Sora asked. He then felt someone tapping on his right shoulder.

"I think you might want to see this, Master Sora." Fang said as Sora turned and saw, written in small scorch marks in the blank spot on the wall, were two words.

"Flynn Lives."

"Flynn Lives? Who's Flynn? His name sounds familiar." Sora asked as he looked up at Fang and Vincent.

"Dunno. Never heard of 'em." Fang said with a shrug.

"I have. He's a computer genius that disappeared a while before the Master arrived." Vincent said. They then heard the computer start humming to life. They turned and saw the screen turn black. Then a few lines of data appeared in blue letters on the screen. But it wasn't data; it was as if someone else had written it. It read…

"The Grid...
…A digital frontier.
I tried to picture clusters of information as they moved through the computer.
What did they look like?
Ships? Motorcycles?
Were the circuits like freeways?
I kept dreaming of a world I thought I'd never see.
And then…
…one day...
...I got in."

They stared at the screen for a long time before they heard a whirring sound. They turned and saw a sheet of paper with the words printed on it coming out of a slot in the machine.

"I figured you might need this." Professor Von Drake said as he handed Sora the sheet of paper.

"What does this mean?" Sora asked, confused.

"Well, Grid sounds like it could mean an electrical grid. If that's the case, then Arlene's the person we should ask." Fang replied.

"Alright, we'll ask her. I want to know who this Flynn is." Sora said as they started heading up the stairs.

"I'll see if I can recover the data, Master Sora!" Professor Von Drake called after them.

…

Sora, Fang, and Vincent emerged outside and found Arlene in the courtyard, working on fixing the mechanical joints in the left gate.

"Hey, Larxene, can we talk to you for a second?" Sora asked.

"I'm very busy, Master Sora, and stop calling me Larxene." Arlene replied as she continued working.

"I think it'll be worth some of your time, Arlene." Fang said as Arlene sighed but she continued working.

"Wrong. I'm trying to get this gate fixed before nightfall. I don't want us going without a place for the people to run to from the Heartless if they get past us tonight." Arlene replied.

"Arlene. Flynn lives." Vincent said, causing Arlene to pause. She then turned towards them, taking off her cap and allowing her antennae like bangs to spring up.

"Okay, say what now?" She asked, confused. Sora handed her the printout of the message.

"The Lab kinda went haywire a few minutes ago and this message was on the computer when we came back in. The words 'Flynn Lives' was burned onto the wall with a laser." Sora explained as Arlene contemplated for a moment.

"Flynn lives. The Grid. Hmm. Well I can tell by the wording it doesn't have anything to do with electricity, but it does have something to do with computers. But the term Grid and Flynn does stick out to me. Grid…where have I heard that before?" Arlene asked. Medy happened to be passing by at that moment and froze when he heard Arlene mention the phrase Grid.

"Grid? Oh that's the name of Nixe's favorite arcade game. See, what you do is you-…" Medy said but was interrupted.

"Arcade games! That's it! Now I remember!" Arlene exclaimed.

"Remember what?" Sora asked.

"Flynn's! That's where I heard the name! Flynn's is the name of an old and shuttered arcade. It's been closed for years and it's a constant source of frustration for me." Arlene grumbled. Medy in the meantime shrugged and continued on, walking into the city and disappearing in the crowds.

"Why's that?" Fang asked.

"Because I keep picking up an energy signature whenever I check the main power lines that run into the area where Flynn's is and I can't cut the power because the same lines connect to an adjacent inhabited block in the Third District and I don't have the manpower or equipment to pull off a rewiring of that magnitude." Arlene replied.

"Then where's Flynn's?" Sora asked.

"Well see, there's the problem. It's in the Fourth District Commons and the Fourth District is off limits." Arlene replied as she crossed her arms.

"Not to a Keyblade Master." Vincent said as Sora looked up towards Arlene.

"Larxene, take me to Flynn's." Sora said. Arlene sighed in exasperation and rolled her eyes simultaneously.

"Alright. Fine. Just quit calling me Larxene." Arlene grumbled as she put her cap back on and led them off towards the Fourth District. As soon as they were out of sight however, two white hooded figures appeared on the roof of the mansion.

"Excellent. With the Keyblade Master out of sight, we can start working on the Apprentice." One of them said before disappearing in a Corridor of Darkness.

…

Sora, Fang, Vincent, and Arlene soon arrived at a building right on the border between the Third and Fourth Districts. Sitting right in the corner lot of a Fourth District block, was a large tan colored brick building with boards over all the windows and an old unlit sign with red letters that read "Flynn's."

"Well, here we are. I'll get back to work now." Arlene asked as she started to slink away but was grabbed by the back of the collar by Fang.

"No you're not." She said as they started heading inside. They opened the front door and saw rows upon rows of strange tan dust colored rectangular boxes creating an aisle towards the back. Arlene reached for a box on the wall and flipped a group of switches. Instantly the boxes lit up from within, revealing that they weren't boxes at all. They were all arcade games covered in dust covered clear plastic drop cloths.

"Wow, this place has everything from Pac-man to Street Fighter, even Fix-it Felix Jr. Talk about nostalgia." Arlene said as she looked around. At the back of the aisle of games was one game that caught Sora's attention. His jaw dropped in surprise at the name printed in blue-silver letters on it.

"TRON!"

"It can't be." Sora said as he ran to the old arcade game.

"Found a game that looks interesting? You know if it wasn't for the Heartless that would steal your heart while you played, I wouldn't mind giving one or two of these old games a spin, myself." Arlene said as Sora ripped the drop cloth off the TRON game.

"Tron! Tron are you in there buddy? Speak to me!" Sora said as he banged on the controls of the machine.

"Uh, Master Sora? Are you alright?" Fang asked out of concern.

"It's an arcade game of a friend of mine. His name is Tron, he's a computer program!" Sora said as he kept banging on the controls.

"Hey-hey-hey-hey-hey! Quit beating on that thing! It's old!" Arlene yelled as she stomped over towards him.

"But…Tron." Sora said as he finally stopped.

"There's nothing here Master Sora." Fang said but Vincent wasn't convinced.

"Arlene, are you still getting that energy signature?" Vincent asked. Arlene sighed and pulled out a small handheld device and waved it in front of him.

"Of course I am. I can't track the source down." Arlene grumbled, kicking the machine out of frustration. However this caused it to make a strange chirp. They turned around and saw, written on the screen in 8-bit letters was the word, "Password" followed by two rows of five letter blanks.

"Password, what password?" Arlene asked confused. Sora then started counting silently on his fingers and just before he got to ten his eyes lit up and he quickly grabbed one of the control sticks, moving it up and cycling through the letters until he found the letter F in the first blank. He then pressed a button and locked in the letter. He began doing the same thing with each blank, cycling through until he found a specific letter and locking it in. About half way through, Fang, Vincent, and Arlene had caught on to what he was doing.

"Well, I'll be." Fang said in awe.

"And you said there was nothing here." Arlene chuckled. Sora finally locked in the last letter, making the password spell out "FLYNN LIVES" on the screen. Instantly the machine powered down and started to slowly swing outward towards them and to the left, revealing a hidden passageway.

"This must be where that phantom energy signature was coming from." Arlene said as they walked inside and down a flight of stairs. They quickly found themselves within a dust covered room with a blank desk below a window on the opposite wall. The walls were lined with old machinery. None of them noticed a strange gun shaped object pointed towards the desk. Sora looked around but saw nothing.

"What is this place?" Fang asked, confused.

"Beats the heck outta me, but now I can pull their plug." Arlene said with a smirk as Sora sighed.

"There's nothing here. It's empty." Sora said, leaning with his hand on the desk. He then heard a computer beep. He looked down at the desk and noticed that the area beneath his hand was glowing. He moved his hand and saw that the desk was actually an entire computer console, complete with keyboard and monitor, on one single desk but covered under a layer of dust.

"I take that back. What's this?" Sora asked as he wiped off the entire computer, revealing the keyboard and screen on the surface. The screen had a countdown timer slowly counting down the hours (Zero) minutes (Zero) seconds (Ten) and milliseconds on it.

"Uh-oh." Arlene blinked as all the color drained from her face.

"RUN!" Fang exclaimed as she and Arlene ran out the door with Vincent hot on their trail. Sora was about to run too but he stepped on a pencil on the floor and slipped, falling to his face.

"OW!" he groaned. He started to climb up onto his feet just as the timer reached Zero across the board and he heard the machinery start humming to life. He then noticed the gun device over the door lower into position in front of the door with a green glow appearing within the barrel. Sora summoned his Keyblade in an effort to defend himself from whatever the gun fired. Outside, the Arlene, Fang, and Vincent heard the sound of the laser firing continuously for a few seconds before stopping. When they realized Sora wasn't with them, they turned and hurried back inside to find the room deserted again.

"Master Sora? MASTER SORA!" Fang shouted but he was nowhere to be found.

"What happened? Where is he?" Arlene asked.

"He's gone! The computer must have completely obliterated him." Fang replied.

"No…he's not gone." They heard Vincent say. They turned and saw Vincent standing outside the room against the wall opposite the machine.

"What? Then where is he? Where can he be?" Fang asked as Vincent looked straight forward.

"The same place where Flynn is."

Elsewhere…

Sora felt himself standing on what he assumed to be solid ground. He then noticed a bright light shining down on him from overhead.

"Ugh, hey! Do you mind!" Sora groaned as he snapped his eyes open only to realize that he was in a vast shimmering city with glossy black walls with white-blue circuit like lines on them and black hexagonally tiled streets. It reminded him of a place he'd been to before only, newer. He then looked down and realized what had happened.

"I'm…in the computer world." Sora realized as he saw himself back in his Space Paranoids form. His circuit patterns had changed dramatically however. Instead of multiple chaotic blue circuit patterns, he had solid black clothing and only a few white lines running over him creating a simple pattern. He had the helmet on his head as well but it was much simpler in design as well but this time he had a clear visor over his eyes. (See A/N) His Master's Haori was still white but the Aqua colored lining now glowed. He then heard a sound coming from behind him. He turned towards the sky and saw what looked like a giant black metal claw with glowing red outlines hovering down towards him. The giant claw touched down on the street and the main body of the claw lowered itself down towards the ground, extending a platform beneath it. On the platform was a lone man in black clothes with yellow-orange circuit lines similar to his in design. He was a relatively young looking man with his hair neatly kept.

"Welcome, User, to the Grid." The man said with a smile as he started to slowly approach with his hands behind his back.

"User? You know I'm a user?" Sora asked curiously.

"Naturally. Although your user name is unknown to me at the present time." The man said, stopping near Sora.

"I'm Sora. I wonder if you know a program named Tron. Is he here?" Sora asked as the man's smile widened.

"A friend of Tron's? I see. Then you must also be here for Kevin Flynn." The man said as Sora's eyes widened.

"Flynn? The guy who left the message in the lab? He's here?" Sora asked in surprised as the man reached right hand over his shoulder towards his back.

"My former User is here. But it is now my directive to deal with any unauthorized access by unregistered Users." The man said as he pulled a doughnut shaped black metal ring off his back. The edge of the ring started glowing with yellow-orange energy. As the ring activated, a number of yellow and red Magnum Loader Heartless appeared around him. Even the Magnum Loader Heartless had been redone with the new circuit patterns.

"Huh? What are you doing?" Sora asked in shock as he dropped into his battle stance. His Keyblade had retained its digital appearance, only this time being summoned in a unique way. It took on a glowing neon white outline of its shape until quickly filling itself in with color, leaving a glowing white line of light along it.

"My directive. You are an unauthorized user, and therefore must be immediately derezzed." The man said.

"Who are you?" Sora asked angrily. The man simply smiled back.

"I am Clu."

End Chapter 12.

The Grid's BGM theme is "Recognizer" from the Tron Legacy soundtrack.

And yes I know that claw thing is called a Recognizer.

A/N: There is an image on the KH Wiki of Sora in his Tron Legacy outfit. You can imagine that outfit when envisioning Sora's Grid Form. Alternatively there's a picture on Deviant Art of Sora, Donald, and Goofy in Tron Legacy styled clothes. I'm basing Sora's appearance off of that picture (But I added the haori). If you want to see the picture, simply go to Deviant Art and search for "Tron Legacy Sora." The picture was made by Lynx Griffin (without the spaces) while not necessarily a song, the part above that talked about the Grid is actually from the TRON Legacy Soundtrack. It's appropriately titled…the Grid.
