The Cyberspace is a result of research from Ciel and her development team from Blazing Umbra Station, looking for a way to solve the main issue they had with The Derelict. The result is a machine that generate a cyberserver, also called semi-dimension in a determined radius that is similar to the real world (everything green though) that can also be manipulated to generate cybernetic objects as well artificial atmosphere inside the space in the determined radius. It's needed at least two people to use the Cyberspace: A Operator and the user.
How it works
Based on the Cyber-elves research, also responsible for the C.I.E.L. System development, once created, the operator of the Cyberspace can set two coordinates that are used as "Gateways" to join in the cyberserver. Those gateways resembles physical titanium doors, but physically they are old-like holograms that if crossed, the user body passes through a process like the Teleport, that will materialize them inside the cyberserver, allowing them to move freely through the Cyberspace like they were in the real world, but with the changes that the operator chosen for that session.
Side effects
Because the development limitations of the Cyberspace, organic individuals can't join the Cyberserver, limiting the use for only Reploids, Androids and robots being able to join the Cyberserver. There's some ways to bypass this issue, but it's necessary another technology created a long time ago by Ciel, called Biometal.
