In WildStar, a Subzone is a specific area within a game Zone and are typically the smallest named areas of a map. Zones are a part of a much larger area called a Region. Typically there are many Subzones spread throughout in a Zone, and can be seen on the UI Minimap, and the larger game Map when opened. See Regions list for a list of game regions, and Zones by region for a list of game zones by region.
