2175 Aeia

World Type: Garden

Richness: Rich

Element Zero: Moderate

Iridium: Poor

Platinum: Rich

Palladium: Moderate

Orbital Distance: 4.5 AU; Orbital Period: 7.3 Earth Years; Radius: 6,521 Km; Day Length: 31.6 Earth Hours; Atmospheric Pressure: 0.72 Earth Atmospheres; Surface Temperature: 16 Celsius; Surface Gravity: 1.1 G.

Description: Named after an asari scientist, this remote planet appears to have been on the list of forbidden mass relays that led to uncharted space.

The little data available comes from one far-off probe flyby that reports two planets orbiting a white dwarf star. Your own scans yield far more interesting results.

The planet is within the habitable zone of the star. It has oceans of liquid water and a thin nitrogen-oxygen atmosphere consistent with carbon-based plant life. It is possible this is an as-yet-unexplored garden world.

2175 AR2

World Type: Giant Jovian

Richness: Poor

Element Zero: None

Iridium: Poor

Platinum: Poor

Palladium: Moderate

Orbital Distance: 9.3 AU; Orbital Period: 28.4 Earth Years; Radius: 62,775 Km; Day Length: 14.0 Earth Hours.

Description: Still formally unnamed, this planet is a hydrogen-helium gas giant with 21 moon-sized objects.

System: Enoch †

Goliath

World Type: Giant Jovian

Richness: Moderate

Element Zero: None

Iridium: Poor

Platinum: Moderate

Palladium: Poor

Orbital Distance: 4.8 AU; Orbital Period: 10.5 Earth Years; Radius: 74,985 Km; Day Length: 14.1 Earth Hours.

Description: A hydrogen-helium gas giant, Goliath’s orbit takes it near the system’s mass relay, a useful event for drive core discharges and automated helium-3 refueling platforms.

Unfortunately, its orbit is currently taking it away from the relay, and it will continue this inconvenience for the next three galactic standard years.

Joab

World Type: Post-Garden

Richness: Good

Element Zero: Rich

Iridium: Moderate

Platinum: Rich

Palladium: Poor

Population: 21,553,000; Colony Founded: 2171; Capital: New Jericho; Orbital Distance: 2.3 AU; Orbital Period: 3.5 Earth Years; Radius: 6,709 Km; Day Length: 25.6 Earth Hours; Atmospheric Pressure: 2.18 Earth Atmospheres; Surface Temperature: 14 Celsius; Surface Gravity: 1.2 G.

Description: Joab is a two-mooned habitable planet that is most well known for its mass extinction event. Thousands of years ago Joab was home to a primate-like spacefaring civilization as well as abundant flora and fauna.

However, this can only be deduced from time capsules put into the ground well outside habitation centers—all cities and detectable dwellings were targeted in a massive orbital bombardment that turned them into vapor.

The resulting dust shroud killed all photosynthetic life and all fauna dependent on it.

Today, humans have recolonized the planet and are rapidly introducing their own species, beginning with cyanobacteria and heterotrophic bacteria, to bring a suitable level of oxygen and nitrogen for respiration.

TRAVEL ADVISORY: Atmospheric pressure at sea level on Joab is double that of Earth. Visitors with upper-respiratory infections, emphysema, cancer, or a history of thoracic surgery should consult their physician before landing on Joab.

Laban

World Type: Desert

Richness: Rich

Element Zero: Moderate

Iridium: Rich

Platinum: Poor

Palladium: Moderate

Orbital Distance: 0.6 AU; Orbital Period: 0.5 Earth Years; Radius: 7,658 Km; Day Length: 24.3 Earth Hours; Atmospheric Pressure: 14.91 Earth Atmospheres; Surface Temperature: 384 Celsius; Surface Gravity: 1.8 G.

Description: Laban is a desert world with sea upon sea of scorching hot iron oxide wearing away marbleized cliffs. Its atmosphere is thick and layered with significant levels of oxygen trapped under an upper helium layer.

Initially, surveyors detected traces of iridium from orbit, only to find a surprising archaeological discovery—the iridium came from bunkers on the surface that were blown apart by a dreadnought-class weapon.

The logical conclusion was that the civilization on Joab had reached Laban and its outposts here were destroyed to make their extermination complete.

Mizraim

World Type: Giant Ice

Richness: Good

Element Zero: Rich

Iridium: Poor

Platinum: Moderate

Palladium: Poor

Orbital Distance: 1.2 AU; Orbital Period: 1.3 Earth Years; Radius: 17,932 Km; Day Length: 10.9 Earth Hours; Atmospheric Pressure: 1.9 Earth Atmospheres.

Description: A small gas giant, Mizraim is primarily hydrogen and methane around a rocky core.

There is no remaining trace of the civilization from Joab on Mizraim itself, but debris orbiting the planet indicates that artificial satellites were once in place before being destroyed.

System: Phi Clio

Cyllene

World Type: Giant Jovian

Richness: Poor

Element Zero: None

Iridium: Poor

Platinum: Poor

Palladium: Poor

Orbital Distance: 0.5 AU; Orbital Period: 0.4 Earth Years; Radius: 38,920 Km; Day Length: 12.8 Earth Hours.

Description: A mid-sized hydrogen-helium gas giant, Cyllene has an automated helium-3 refueling station, indicating that this remote system was once inhabited.

Its distance from the mass relay and archaic design of the fuel station suggest that this system was mapped by someone who did not go through the relay but discovered it in independent FTL exploration.

Cyllene is within the “frost line” of its parent star, where gas giants do not normally form. For this reason Cyllene is believed to be an extrasolar capture.

Parnassus

World Type: Rock

Richness: Rich

Element Zero: None

Iridium: Rich

Platinum: Moderate

Palladium: Poor

Orbital Distance: 1.1 AU; Orbital Period: 1.2 Earth Years; Radius: 5,850 Km; Day Length: 50.2 Earth Hours; Atmospheric Pressure: 4.71 Earth Atmospheres; Surface Temperature: 158 Celsius; Surface Gravity: 0.8 G.

Description: A boiling hot rock planet with extreme tectonic activity, Parnassus is home to many volcanic mountains.

Surface scans reveal several geothermal and solar power stations tapping the planet’s abundant energy.

There is no history of the planet or its government in Citadel Council records. Given its proximity to a mapped and recorded planet like Cyllene, someone must have deleted Parnassus from the database.
