"It is nice to meet you Susan. Mainframe is my home city. It is a small system, I'm not surprised you haven't heard of it." After a moment of thought it occured to Bob that this system may not have had contact with the Net yet.
"I'm from an order dedicated to the protection of innocents from danger, primarily viruses. The Guardians. There is a huge number of worlds outside the confines of this place. Mainframe is one of these. Glitch: Net diagram" he said, as Glitch activated on his arm and began to project a diagram of the known Net and Mainframe's location.
"Each of those dots is a system, like this one. My friends are in terrible danger. If there's a way for me to return to them, I need to use it soon."
