Center Zero is an organization to which all the world's intelligence agencies legally transfer information without knowing it themselves. As it turns out later, this transfer was agreed upon by a super-secret group called "the Collegium", which includes gray cardinals, the rulers of the world. Accordingly, the center "Zero" controls everything and everyone in the world. But it turns out that for many years this is not the main concern of the collegium, but something else, labeled by the secret term "problem". Under this term lies the top-secret Perimeter program, created back in the USSR, which controls the entire strategic nuclear stockpile of Russia. It cannot be turned off, it operates autonomously and can launch missiles from any carriers and points at any time it deems necessary; it is connected to all communication systems, seismic stations and satellites in orbit to collect information; in fact, it is an artificial intelligence.
