In the world of Fabricated life as we know it has been lost to a distant tragedy forgotten by most. In place of that life, is now a sprawling world of machines. Above the, the system itself is their lifeblood and from which they were born. These machines are broken down into the following categories: POP Units, Beeps, Bloops, and Dots.

POP units are machines with special privileges. Only POP units can recognize another POP unit at a glance. All other machines see them as one of their own, so POP units get to blend into most situations until they take action that makes them stand out. Once that happens, other units see them as faulty machines of their type and often respond badly.

So what is a POP unit? It is a machine built for the Perfectly Ordinary Person (POP) program of the system. Each unit has a Brain-AI-Technology (BAT) Core at it's heart, which is the hardware that contains it's mind. The units call this their Code. It is moving Fiber around run by that Code, and all wrapped up in Metal. There are a lot of details under the ideas of Code, Fiber, and Metal:

• Code: This is the technology of the BAT core and how it links into (and through) the Fiber of the unit. Code has both a Width and a Complexity. Width gives the unit the ability to multitask, as the cost of action effectiveness. Complexity changes the way the unit connects to other machines, relating to protocol and cryptographic functions.
• Fiber: This is what makes the machine move. Code moves through fiber so they are closely linked. Fiber has both a Process and an Endurance. The Process describes how the fiber was made, and impacts a lot of machine stats. Endurance is a straight relationship to maximum output power and hold-up time, you can have one but not the other.
• Metal: This is the casing of the Fiber and Code. Metal has both a Size Class and Print Generation. The Size class impacts how the machine can interact with the world around it, and the Print generation tells us which factory made it. As changes to the production of unit machines changed over the eons, the factories themselves changed. However none of them ever shut down, and machines are still produced as each.
