About the title
The near future. The world has been devastated by World War III, which caused key ecosystems to collapse, and North America has been divided into four main quadrants. Thanks to scientist Ion Prescott, humanity managed to avoid extinction. Prescott's company Alpire created Onyx - a deadly nanovirus that spreads through watches, infects its wearer, and points them to a target for elimination in exchange for the antidote.
