Janus is the top-secret project at the heart of the Network's machinations. It is a serum developed initially by Philip Carvel. Its purpose is to sterilize 90-95% of the human population in order to prevent the destruction of the Earth's environment and the descent of humanity into wars over food shortages. It is split into two parts to avoid detection: a protein called GCHN1 which is added to all industrially farmed corn, and an amino acid put into the vaccine for Russian flu.
