Cities
Following the Combine's dissolution of Earth, the reconstructed areas were given a specific designation and evaluation by the Combine to pen in its workforce, even if it is temporary.
Organization
Earth
Earth, designated CMB-314, is one of the planets under the Combine's domain. They have appointed an 'Interim Global Administrator' to act on their behalf with the management of its population - George Martreen.
Sector
Sectors are continent-sized regions that encompass multiple cities and the outland regions inbetween. The Transhuman Arm and Overwatch A.I. are established in black sites and outposts on the sector level. The Sector Administration typically operates out of the largest city in the region.
City
Cities, or Urban Locations, are metropolitan areas that house the majority of the remaining human population. Most of these are headed by a Security Council which reports back to the Sector Administration.
District
Districts, or Indexes, are the subdivided regions within an urban location, established to micromanage aspects of citizen life and to allow for easy sterilization or control of an outbreak within the city. Citizens are denied free movement between districts by the Civil Protection.
Outside the walls
As the Combine began to construct and develop cities upon the now enslaved Earth, many inhabitants were desparate to escape the walls, convinced that life outside would be better. They were wrong. The immense resource harvesting of the Combine had led to the Earth losing almost two-thirds of its ocean water, consequently turning most all landscapes into barren deserts.
Those who live to share rumors report on an apocalyptic wasteland desolate of life, aside from the occasional portal storm by-product. Perhaps there is something out there, though nobody's the wiser as to where.
Symbols
Some Overwatch forces don insignia that detail their assigned locations.
For example, c̄17:i4 refers to City 17 District 4, c̄24:i1 refers to City 24 District 1, c̄08:i5 refers to City 8 District 5, and so forth.
