Planets Directory:

  1. Agetoton
  2. Ilos
  3. Zafe

 

Agetoton:

  • Orbital Distance:  N/A AU
  • Orbital Period:  0.4 Earth-years
  • Keplerian Ratio:  N/A
  • Radius:  6,172 km
  • Day Length:  53.5 Earth-hours
  • Atmospheric Pressure:  84.30 atm
  • Surface Temp:  510 °C
  • Surface Gravity:  1.0 g
  • Mass:  0.929 Earth-masses

Agetoton has a pressure-cooker atmosphere composed of carbon dioxide and ethane. Its scorching hot surface is mainly composed of sulfur with deposits of gold. Surface gravity is comfortable at 1.0 standard G’s.

There are several areas of debris that may be the wreckage of downed Prothean aerostat colonies. Based on the size of the debris fields, a population of over 100,000 was likely.

 

Ilos:

  • Orbital Distance:  N/A AU
  • Orbital Period:  261 Earth-years
  • Keplerian Ratio:  N/A
  • Radius:  8,607 km
  • Day Length:  54.5 Earth-hours
  • Atmospheric Pressure:  11.26 atm
  • Surface Temp:  38 °C
  • Surface Gravity:  1.17 g
  • Mass:  2.115 Earth-masses

In the golden age of the Protheans, Ilos was a verdant world, dotted with the spires and arches of magnificent cities. Even casual observation shows this is no longer the case. Ilos has been devastated by means unknown, its entire surface changed to the color of rust. The atmosphere shows heightened levels of oxygen. Wildfires, presumably ignited by lightning strikes, can be seen burning on the dark side. This indicates that most – if not all – respirating animal life forms have died off. Surface gravity is a comfortable 1.17 standard G’s.

Codex Entry
Like the ancient human city of Troy, Ilos is a world known only through second-hand sources. References to Ilos have been found at several other Prothean ruins, though direct study of the world is unlikely to occur.

Ilos lies in a remote area of the Terminus Systems only accessible by the legendary Mu Relay. Four thousand years ago, the Mu Relay was knocked out of position by a supernova and lost. Since then, Ilos and its cluster have been inaccessible.

Occasionally, a university will organize an expedition to chart a route to Ilos using conventional FTL drive. These never get beyond the planning stages due to the distance and danger. The journey could take years or decades, passing through the hostile Terminus Systems and dozens of unexplored systems.

 

Zafe:

  • Orbital Distance:  N/A AU
  • Orbital Period:  33.8 Earth-years
  • Keplerian Ratio:  N/A
  • Radius:  30,488 km
  • Day Length:  12.2 Earth-hours
  • Atmospheric Pressure:  N/A atm
  • Surface Temp:  N/A °C
  • Surface Gravity:  N/A g
  • Mass:  N/A Earth-masses

Zafe is a relatively small hydrogen and helium gas giant. There are several tenuous belts of debris in equatorial orbit. Spectral analysis of the material suggests artificial origin, perhaps the remains of stations that once mined Zafe for helium-3.
