The year is 2156. A century has passed since the virulent Shiva plague first appeared. The lethal contagion spread rapidly to all corners of the world. Perhaps partly due to the fear it engendered, a ferocious nuclear conflict ensued. The Earth was devastated, its population pushed to the verge of extinction. Amid the massive death and destruction, few areas remained fit for human habitation. Even there however, what now passes for civilization reflects the radically changed environment. Resources are extremely scarce, so the competition for them is savage. Life is a constant, daily struggle to obtain enough just to survive.
