Colonies Sphere — Districts

Detail of three-dimensional game space of the Earth Colonies Sphere (illustration by Redmond Simonsen from StarForce: Alpha Centauri)

District is the nomenclature developed by the Prometheus Foundation for a standard astrographic region defined as a rectangular cube measuring eight parsecs spin-trailward by ten parsecs core-rimward by nine parsecs up-downward and divided into 720 volumes of one cubic parsec each called "hex-prisms."  The Colonies Sphere is not actually a sphere but rather a rectangular volume of 64 Districts measuring 32 parsecs (spin-trailward) by 40 parsecs (core-rimward) by 36 parsecs (up-downward).  Each of the 64 Districts is identified by a distinct name and location within the overall volume.

A "Disc" is the set of planes corresponding to the nine core-rimward / spin-trailward "discs" along each zenith-nadir ("zz") coordinate of a District, giving a rectangular volume measuring 32 parsecs by 40 parsecs by nine parsecs and comprised of the "discs" of sixteen Districts.  There are four Discs in the Colonies Sphere, identified as Discs 1 through 4, moving from upward to downward.

A "Ring" is the set of planes corresponding to the ten spin-trailward / up-downward "rings" along each core-rim ("yy") coordinate of a District, giving a rectangular volume measuring 32 parsecs by ten parsecs by 36 parsecs and comprised of the "rings" of sixteen Districts.  There are four Rings in the Colonies Sphere, identified as Rings 1 through 4, moving from coreward to rimward.  (Because the Colonies Sphere is so distant from the galactic core, the sections of these Rings in the Sphere can be assumed to be parallel to each other.)

A "Spoke" is the set of planes corresponding to the eight core-spinward / up-downard "spokes" along each spin-trailing ("xx") coordinate of a District, giving a rectangular volume measuring eight parsecs by 40 parsecs by 36 parsecs and comprised of the "spokes" of sixteen Districts.  There are four Spokes in the Colonies Sphere, identified as Spokes 1 through 4, moving from spinward to trailwardward.  (Because the Colonies Sphere is so distant from the galactic core, the sections of these Spokes in the Sphere can be assumed to be parallel to each other.)

Districts shown in grey shading below have yet to be charted by the Commonwealth Scout Service, the Discovery Service of the Abrahamic Synod or the Vanguard of the Empire of Atzlán.  In some cases, the major worlds in a District are also identified along with their location.
