Uruz:

  • Orbital Distance:  0.25 AU
  • Orbital Period:  0.1 Earth-years
  • Keplerian Ratio:  1.563
  • Radius:  9,266 km
  • Day Length:  51.0 Earth-hours
  • Atmospheric Pressure:  78.58 atm
  • Surface Temp:  635 °C
  • Surface Gravity:  2.1 g
  • Mass:  4.399 Earth-masses

A large rock planet with a pressure-cooker atmosphere of nitrogen and argon, Uruz’s silicate-rich crust is relatively low density. It was largely ignored by the salarian explorers who first charted the system.

Kenaz:

  • Orbital Distance:  0.55 AU
  • Orbital Period:  0.5 Earth-years
  • Keplerian Ratio:  0.666
  • Radius:  5,501 km
  • Day Length:  68.3 Earth-hours
  • Atmospheric Pressure:  Trace atm
  • Surface Temp:  72 °C
  • Surface Gravity:  0.69 g
  • Mass:  0.509 Earth-masses

Kenaz’s extremely thin atmosphere is mostly methane and helium. The salarian explorers who named the system set up a small mining presence for recovering nickel and chromium, used in making stainless steels.

Hagalaz:

  • Orbital Distance:  0.95 AU
  • Orbital Period:  1.0 Earth-years
  • Keplerian Ratio:  0.857
  • Radius:  6,309 km
  • Day Length:  98.3 Earth-hours
  • Atmospheric Pressure:  0.83 atm
  • Surface Temp:  72 °C (day), −64 °C (night)
  • Surface Gravity:  0.69 g
  • Mass:  0.67 Earth-masses

Hagalaz is a second-tier garden world that receives little attention from the galactic community. A salarian mining expedition initially discovered the planet, which was promptly strong-armed away from them by organized crime figures. Hagalaz’s exploration rights were then sold to the highest bidder, which led to a brief burst of mining colonies in the 2000s, but most of those were abandoned when other planets were found with more accessible resources.

Though Hagalaz has a nitrogen-oxygen atmosphere capable of supporting life, its rotational period is slower than Earth’s, making its day and night 98 Earth days long. The intense heat on one side of the planet and the extreme cold on the other make for violent storm cells wherever the sun is rising or setting. As a result, the flora and fauna of Hagalaz have developed the capability to live in cycles of ice, flooding, baking heat, and dramatic air pressure changes. The biota of the planet has been largely unexploited by the exotic pet and gardening trades, since simulating their natural conditions is problematic for the average consumer.

Ansuz:

  • Orbital Distance:  1.6 AU
  • Orbital Period:  2.0 Earth-years
  • Keplerian Ratio:  1.024
  • Radius:  8,795 km
  • Day Length:  26.4 Earth-hours
  • Atmospheric Pressure:  0.14 atm
  • Surface Temp:  −7 °C
  • Surface Gravity:  2.7 g
  • Mass:  5.096 Earth-masses

A large rock planet, Ansuz was once under development by a consortium of robo-mining interests, but an epidemic of accidents and sabotage cost the lives of hundreds of workers and eventually drove them off the world. Despite numerous accusations among the mining corporations and a dozen or more trials, popular opinion holds that the real saboteurs were never found.

Thurisaz:

  • Orbital Distance:  3.0 AU
  • Orbital Period:  5.2 Earth-years
  • Keplerian Ratio:  0.999
  • Radius:  57,287 km
  • Day Length:  18.8 Earth-hours
  • Atmospheric Pressure:  N/A atm
  • Surface Temp:  N/A °C
  • Surface Gravity:  N/A g
  • Mass:  N/A Earth-masses

A hydrogen-helium gas giant, Thurisaz has a decrepit automated infrastructure for refueling merchant vessels with helium-3. Painted onto the metal in a salarian dialect are the words “Self Serve.”

Isa:

  • Orbital Distance:  5.4 AU
  • Orbital Period:  12.6 Earth-years
  • Keplerian Ratio:  0.992
  • Radius:  7,219 km
  • Day Length:  66.5 Earth-hours
  • Atmospheric Pressure:  Trace atm
  • Surface Temp:  −135 °C
  • Surface Gravity:  1.5 g
  • Mass:  1.907 Earth-masses

A rock and ice planet, Isa has a thin atmosphere of methane and ethane. Its borax deposits, largely trapped beneath the ice, were never considered valuable enough to mine since synthetic substitutes and alternative sources became widely available.
