(Y/N): What the? 

You woke up with digitized clothes. 

(Y/N): What the? 

???: Stay right there User. 

A bunch of Heartless surrounds a man.  

(Y/N): Who the hell are you? 

Sark: My name is Commander Sark. 

(Y/N): What are you- 

He zaps you with data! 

(Y/N): ARGH! 

Sark: Stay confined in your cell with your friends. 

He leaves you there as everyone woke up. 

Girls, Sora, Donald, and Goofy: (Y/N)! Are you okay? 

(Y/N): Yeah. Damn that bastard. Where are we? 

???: This is a mainframe computer system.

A man is standing nearby. 

Sora: Say what? 

Tron: A computer system---for processing data. This system is a copy of one created by a corporation called ENCOM. The original program was destroyed. But this copy was acquired by another User. The new User updated and customized the programs, renaming the system "Hollow Bastion OS." He used the system for town maintenance, and to advance his private research. My name is Tron. I'm a security program. But now I'm under arrest, same as you.

(Y/N): I'm (Y/N). 

Ruby: I'm Ruby. 

Sora: I'm Sora. 

Blake: I'm Blake. 

Weiss: I'm Weiss. 

Donald: I'm Donald. 

Yang: I'm Yang. 

Goofy: And I'm Goofy. 

Tron: That would make you Users. 

Sora: Users?

Tron: You'd better get out of here quickly. Who knows what the MCP will do to you?

(Y/N): And who exactly is the MCP? 

Tron: The Master Control Program. It controls the whole system. If you idle here, you will be de-rezzed.

Ruby: DEREZZED?! Like killed? 

(Y/N): How can we escape? 

Tron: This terminal could've gotten you back to the User world. But the MCP cut the power 50 microcycles ago. If we could bring the energy core in the canyon online, we could power it back up. The problem is---we're stuck in this cell. We're not going anywhere unless we unlock the energy fields.

(Y/N): Shall we Sora? 

Sora: Right! 

You both use your Keblades to unlock it! 

Meanwhile... 

Sark is talking with the MCP. 

Sark: Master Control. Why not just de-rezz Tron?

MCP: I still haven't located the password to the dataspace.

Sark: What about a logic probe? With all your processing power...

MCP: Out of the question. The current environment hampers the processing power needed for such an analysis.

And alarm then begins to sound. 

MCP: You're dismissed, Sark. Stop any remaining anomalies in the system---or else. End of line.

Sark: Acknowledged.

Back with you guys... 

Tron: Remarkable... It seems you have some unique functions. I'll go with you to the canyon. You'll need someone who can interface with the energy core, right?

(Y/N): Thanks Tron! 

With Tron's help, you guys find the energy core... 

You and Sora install the missing part, and Tron gets to work! 

Tron: That should do it. 

Sora: Mission accomplished?

Tron: Yes. Now...will you do something for me?

Ruby: Okay! 

Blake: What is it? 

Tron: Follow me to the pit cell. 

You guys went back to where you first met Tron. 

Tron: I need you to find my User. He'll give you the password to access the DTD. DTD is the name my User gave to the dataspace. Copies of all the original system programs are stored there, along with anything that's sensitive or restricted.

Goofy: Is there stuff about the Heartless, or Organization XIII?

Tron: Hmm...Most likely.

He begins to work on the terminal. 

Tron: A number of my functions were appropriated when I last took on the MCP. That's why I need the password. If I can get inside the DTD, I can access my original backup program and restore all my functions. Then, I'll be able to put this system back the way it was before the MCP got control and changed everything. The way it was supposed to be---a free system for you---the Users.

Blake: Hey Tron, isn't the MCP one of those? Who made it? 

Tron: Actually...I don't know.

Sora: Okay, we'll just have to find your user and ask him. What's his name?

Tron: You mean you don't know? My user is the user of this system: Ansem the Wise.

(Y/N): Oh, Ansem, that's-

Tron: Okay. You're good to go. Hurry!

You guys then return to Hollow Bastion to find the password!
