Description The Hoku (which by the way, isn't the name of the species, it would be more like calling humans "Romans", or "Egyptians") homeworld is located some 120 light-years from the Dominion capital Argost, and their domain surrounds five other nearby star-systems. A small territory compared to the way older and more advanced races of the Dominion like the Arrenes themselves, which try to maintain the Dominion cohesive.

In particular, there isn't much of anything special about this system against the greater scope of the Dominion, it is by any measure a typical system, with a few hot-neptunes, super-earths in the habitable zone, large gas giants and a myriad of dwarf planets, but it is still interesting nonetheless. (I really mean it, for sun-like stars I picked typical planet masses against their orbital period)

For being a double-star system, planets cannot form within a certain distance from the stars, for the difference in orbital velocity of particles exceeds the gravitational binding force of planetesimals, yet, we find the innermost planet way inside this area which would be the inner edge of the debris disk had it not moved there. In fact, the debris disk is lacking both edges because the two innermost planets 'ate' them during its early development.

NAME // Symbols used for the name

Bagede // BGD
The fast trickster, joker.
   Hot-Neptune, ~116°C
Mass 20.95 Earth-masses
Radius 6.43 Earth-radii (thermally expanded)
Semi-major axis 0.33 AU
Orbital eccentricity 0.211
Orbital period 69 Earth-days (nice!) or 52.4 Hoku-days

Bagede’s orbit is quite anomalous given the system’s distribution of mass, no planets could form this close to the binary pair, the atmospheric escape rate does indicate it to have formed much further away from the binary, being flung into a tight eccentric and inclined orbit in the system’s deep past.


Ovilgeza // OVGZ
God of lightning, fire, archery, and messengers.
Hot-Neptune, ~18°C
Mass 24.54 Earth-masses
Radius 6.74 Earth-radii (thermally expanded)
Semi-major axis 0.59 AU
Orbital eccentricity 0.024
Orbital period 168 Earth-days, or 127.4 Hoku-days

Ovilgeza is one planet believed to have been quite disturbed by the migration of Bagede, with a tighter orbit than what its size would indicate, this can be said because the both ends of the debris belt around the binary pair are missing, with the missing mass being distributed to the two inner planets.


Auot’zae // AUTZAE
Orb of the World, the Earth.
Tropical Superterran, ~17°C
Mass 2.54 Earth-masses
Radius 1.42 Earth-radii
Semi-major axis 0.80 AU
Orbital eccentricity 0.014
Orbital period 263.3 Earth-days, or 200 Hoku-days

Has a small moon with half the mass of Luna.

Informally known as Hokushoku (the Hoku World, in the classical language) throughout the Dominion, it is the only planet in the system naturally capable of hosting Life as we know it, it is the homeworld of the Hoku. On the surface it is pretty similar to Earth, both in gravitational acceleration and landscape-wise, the planet was once covered in lush bright-yellow vegetation which nowadays struggle to get a foothold, due the destruction of the ozone layer by a hostile force. The planet has one small moon, but due the closer distance it creates tides stronger than Earth’s moon.


Namenza // NAMZ
Goddess of spring, harvest, and life.
Icy Superterran, on average -44°C
Mass 3.55 Earth-masses
Radius 1.70 Earth-radii
Semi-major axis 1.21 AU
Orbital eccentricity 0.019
Orbital period 1y120d, or 1Hy92Hd

Namenza is a bright icy world, its nitrogen and carbon dioxide atmosphere is just thick enough to maintain some levels of liquid water on the surface of the planet. However, despite the friendly conditions for life, it is completely sterile. It happens to be that the amount of volatiles in the planet's upper layers cannot generate enough pressure for efficient plate tectonics, thus the surface is pretty stagnant of chemical recycling. The crawling slow increase in Paza’s luminosity is also blamed to have kept this planet way too long in the dark to feed the chemical processes leading to the genesis of life, and now the planet is an icy wasteland, much contrary to the goddess it was named after.
