Factions or Groups of Note

• Safeguard - The Safeguard is the completely independent defense system of the Netsphere. The Safeguard's original purpose was to prevent unauthorized access to the Netsphere by those without Net Terminal Genes. However, due to the Order breeding and using humans without Net Terminal Genes to make more Silicon Life, the Safeguard have taken to destroying all humans without the Net Terminal Gene as a preemptive measure. Safeguard are often seen to materialise from the substance of the megastructure using substance conversion towers. Even humans have been turned into Safeguard after coming into contact with Safeguard weapons designs to put them in contact with the towers. There are more powerful special agents, like Sanakan, Dhomochevsky, Iko, and Killy who may derive from core personalities residing in the Netsphere, and the bio-mechanical transporter that attacks the Electrofishers.

• Exterminators - A subset of Safeguard which is made up of black-and-white-colored, silicon-based, bio-mechanical, humanoid robots. These often use primitive, close-range weapons as a means of attack, but because of their formidable armor, it is not much of a problem. They come in different classes of power, though the hierarchy is never explained. The lowest, most common safeguard attacks with just its hands. A higher type attacks with larger, clawed hands, another with large shear-like weapons. There are defense exterminator types, feminine in appearance, with four clawed arms and powerful brute strength designed to prevent travel between certain levels. Finally, there is "Class One", encountered in one of the chapters. It is larger in size and is capable of telekinesis, regeneration, and powerful beam attacks.

Safeguard Exterminators seem to run on a different protocol of command than the higher level of Safeguard such as Sanakan and/or Dhomochevsky (though Dhomo did have a contingent of them assigned to him before Schiff destroyed them). At one point, the Exterminator Class One even targets Sanakan as it deems her a threat or obstacle, but does not decide to kill her. It is up to speculation as to why - perhaps either it no longer saw her as a threat, or perhaps it was because she too was a Safeguard.

• Governing Agency or Authority (originally Touchikyoku (統治局?)) - The ruling level of the Net Sphere. It tries at times to assist Killy and Cibo against the Cyborgs and against the Safeguard. It has powers identical to the Safeguard, but cannot directly control the Safeguard - although it can hinder them. It wants a human with the Net Terminal Gene to be found to stop the Builders which are the cause of the runaway growth of The City.
• Builders (originally Kensetsusha (建設者?), meaning Architect) - Machines which construct The City. They are not connected directly to The Net Sphere or Safeguard; therefore a human with net terminal genes is only capable of their activation. They come in a wide variety of shapes and sizes. Killy remembers their language in the village of the Fishermen, and Cibo uses her knowledge about them to learn to control them completely. A group of builders in the higher megastructures of The City have been modified, possibly by long deceased humans, to behave socially, conversing with the beings they encounter and taking moderately humanoid appearances.
