Unlike sectors which are volumes of space, subsectors are blocks of systems and worlds that can be more practically patrolled by ships. {{Fn|1}} Subsectors are centred around populated or important worlds or where warp trade routes meet.{{Fn|1}}{{Fn|3}}<!-- vast numbers of [[System|star systems]] within each sector do not fall within a subsector. These are referred to as inter sectors - and are commonly known as wilderness zones, forbidden zones, empty space and frontier space. Inter-sectors may contain gas or dust nebulae, inaccessible areas, alien systems, unexplored systems, uninhabited systems and uninhabitable worlds.-->
