Small nanobots nicknamed “The Mist” have covered the world, except for a few mountain peaks. Eventually, small cities grew on these, isolated from each other, each thinking they're the only ones left. You are a scavenger, and your job is to dive into The Mist and retrieve items and medicinal herbs to sell for a living. There in the ever-present danger of pirates, as well as dangerous animals such as bears and raccoons. Always the raccoons.
