Code 0

Code 0 (or 'the great divide') is the ultimate realm located within the cyberworks. Within it, the mind transcends into another dimension of reality. It was created by the government as the successor to digital software, but they soon lost control; it is infamous for its crime networks and groups within it, which basically have total control of it by 2117. It serves as the basis of the Sky (the underground). Fighters and attackers are often employed by the government to go in and protect networks or destroy these criminals.

The realm is also notorious for its large 'monster' viruses of jumbled code that can attack or suck unlikely visitors into darkness. One can enter Code 0 through 'logging in' to a BPT machine (Binary Psyche Transmitter), which are hard to find and not openly available to the public.
