The Nivenian Empire only has direct control over one star system, and directly claims everything within one light-year. However, only the region of space within about 3500 AU of the system is defendable. Outside of the system proper is the interstellar cometary cloud, starting approximately 800 AU away from the center of the binary. This cloud, stretching into the void, is home to millions, possibly billions of breakaway colonies that vie for independence and autonomy. While these colonies do not attack, only defend, rumors of a larger empire inhabiting a rouge planet are rampant within the empire. While speeds of 0.09 c are easily attainable using fusion, the need for weapons and life support on most ships limit their maximum speed to 0.055 c. Faster military vessels designed for speed can reach 0.085 c, but anything beyond about a year away cannot be easily patrolled, and anything outside the system proper cannot be patrolled well, allowing for "pocket colonies" of thousands to millions of inhabitants to spring up on long-period comets, powered by nuclear fusion and apt at recycling so as to render imports unnecessary.

Two other systems (Paulo Fluctus Beta and Caeruleo) are indirectly controlled by the Nivenian Empire, though since these systems are too far from the Nivenia System to be directly controlled, vassal governments were created that pay tribute to the Nivenia System in the form of energy or money in exchange for diplomatic unity and the exchange of research data. These colonies have limited autonomy in the sense that they can run their immediate area however they want, but have to obey some Nivenian documents (basically a mandatory constitution) preventing things such as communism and surveillance states. While Thadus 0037 is controlled by a military junta supposedly loyal to the Nivenian Empire, they have no valuable resources, do not have to pay tribute, and do not get research updates.

Neighbors include the New Cyrannian Republic, approximately 138.7 light-years away.

Coordinate Systems[]

Stellar[]

The Nivenian Empire's mapping system splits space into categories, depending on which star is the closest, and uses separate spherical coordinate systems[1] for each category. Then, a position is specified by the the natural logarithm of the radius from the closest star in meters, and the polar and azimuthal angles measured in radians. The zenith direction is taken to be the axis of rotation of the star at the center, with an azimuthal reference direction found by projecting the direction vector of the line between the galactic center and the star in question onto the ecliptic planet of the star at the center.

Coordinates are expressed as follows:

SYS-#-R-P-A

  • -SYS is the system designation. Systems close to Nivenia (NIV) have short system designations, like CAL for Caeruleo, or PFB for Paulo Fluctus Beta, but systems much farther away have longer designations.
  • -# is the number of the star used in the coordinates. Generally speaking, if two stars orbit each other, and neither one has planets, then the barycenter is counted as one star. Then, the most massive "star" found in this method is A, the second most massive is B, etc.
  • -R is the centerpoint of the natural log of the radius in the coordinates, P is the centerpoint polar angle, and A is the centerpoint azimuthal angle.

Stellar Region π/200 π/200 π/200 23.50 Gm
Stellar Sector π/2000 π/2000 π/2000 2.350 Gm
Stellar Subsector π/20000 π/20000 π/20000 235.0 Mm

Galactic[]

The galactic coordinate system is similar to the stellar system, but is a single coordinate system, centered at the galactic core of the Cyrannus galaxy, with the line between Cyrannus' core and the barycenter of the Nivenia System being the azimuth reference direction, and a zenith direction equal to the direction vector of the angular velocity vector of the Cyrannus galaxy.

Type Accuracy of ln(Radius) Accuracy of Polar angle Accuracy of Azimuthal angle Approximate size at 22.14 kly (distance of the Nivenia System from the galactic core)
Galactic Octant π/2 π/2 π/2 34.78 kly
Galactic Suboctant π/20 π/20 π/20 3.478 kly
Galactic Region π/200 π/200 π/200 347.8 ly
Galactic Sector π/2000 π/2000 π/2000 34.78 ly
Galactic Subsector π/20000 π/20000 π/20000 3.478 ly
Galactic Minisector π/200000 π/200000 π/200000 3.290 Pm
Galactic Microsector π/2000000 π/2000000 π/2000000 329.0 Tm

Coordinates are expressed as follows:

GAL-R-P-A

  • -GAL signifies galactic coordinates.
  • -R is the centerpoint of the natural log of the radius in the coordinates, P is the centerpoint polar angle, and A is the centerpoint azimuthal angle.
