Yesup is a poor, low-population desert hellworld, with a population of less than 10,000 sophonts struggling to survive in a inhospitable environment.
- Living on a hellworld is a constant struggle. Nearly every day and sometimes even hourly, the inhabitants of this world face life-threatening challenges.
- This world has no free-standing water.
- It is a Non-Aligned world dominated by human sophonts located in the Esser Subsector of Divide Sector.
Astrography and Planetology[edit]
This star system is detailed using the Fringian Variant System Description.
- It is a part of the Bright Peninsula.

System Data[edit]
Belus-Ageor-Yesup System[edit]
The primary is Belus, a dim red main sequence star. It has a luminosity of 0.004 Sols, a mass of 0.273 Sols, and a diameter of 414,000 km. The companion is Agenor, a dim red main sequence star. It has a luminosity of 0.0025 Sols, a mass of 0.244 Sols, and a diameter of 334,000 km. The two stars are a close binary pair and orbit their barycenter at a mean separation of 0.005 AU (748,000 km). They have an orbital period around one another of 4 hours 18 minutes. (I) a sparse rocky planetoid belt, (III) Porvia, a large gas giant: (IIIb) Yesup is its second moon and is designated the mainworld, (IV) a thin atmosphere bigworld, (V) a large gas giant, (VI) a small gas giant, (VII) a small ice giant, (VIII) a vacuum iceworld, and (IX) a vacuum worldlet form the outer system – orbital position (II) is empty. All of the giant worlds retain satellites.
(III) Porvia[edit]
(III) Porvia is a large gas giant that orbits Belus and Agenor at a mean distance of 0.74 AU, within the outer system, and has an orbital period of 316 days 20 hours. It has a diameter of 103,000km and an atmosphere consisting of 93% hydrogen (H2), 7% helium (He), and less than 1% methane (CH4), carbon monoxide (CO), ammonia (NH3), water vapor (H2O) and other trace gases. It is a deep reddish-brown color with distinct paler bands. It retains a family of four major satellites.
Satellites[edit]
Porvia retains four major satellites:
- (IIIa) Bach (UWP Y211000-0, orbiting at 7 Diameters/720,000 km)
- (IIIb) Yesup (designated the mainworld, orbiting at 12 Diameters/1.24 million km)
- (IIIc) Oice (UWP Y3A0000-0, orbiting at 14 Diameters/1.44 million km)
- (IIId) Corut (UWP Y100000-0, orbiting at 20 Diameters/2.06 million km)
Mainworld Data[edit]
(IIIa) Yesup[edit]
(IIIa) Yesup is designated the mainworld and orbits Porvia at a mean distance of 12 diameters (1.24 million km). It has an orbital period of 120 days 11 hours: it is tidally locked to Porvia. The axial tilt is 5 degrees relative to Porvia. Yesup has a diameter of 4,931 km, a density of 4.86 g/cm³, and a surface gravity of 0.34 G. Tidal stresses generated by the gravitational pull of Porvia cause constant geological activity. Its atmosphere is rated as Thin, Tainted, with a mean surface pressure of 0.52 bar and a composition of 88% nitrogen (N2), 9% oxygen (O2), 2% carbon dioxide (CO2), and 1% argon (Ar), carbon monoxide (CO), sulfur dioxide (SO2), neon (Ne) and other trace gases: the taint is caused by the very low percentage of atmospheric oxygen, gases of volcanic origin and the relatively high levels of background radiation: emission rates exceed 8 rads per hour. Yesup is a desert world: approximately 4% of the surface is covered in sheets of water-ice and lakes of water kept liquid by geothermal activity. Mean surface temperature: -172°C. The climate is rated as Frigid and is static, with no seasonal changes during the local year. The atmosphere is sluggish and weak weather systems driven by the two central stars drift across the globe.
Mainworld Geography and Topography[edit]
Total surface area: 76 million km², Land surface area: 73 million km², Ice and Water surface area: 3 million km², of which approximately 800,000 km² (2.5% of the surface area) is liquid water. The surface is dotted with geologically active areas where temperatures are significantly warmer. Geysers of gas and superheated water, many hundreds of meters in height, erupt from the worlds interior. The water freezes in the air, falling back to the surface as ice. Where this lands in geologically warmed areas it forms into small lakes: these are surrounded by ice fields. Much of the rest of the world is arid and frigidly cold, dominated by dusty flatlands, boulder fields and cratered terrain.
Native Lifeforms[edit]
Belus-Ageor-Yesup System[edit]
Yesup, the mainworld, has extensive native life, entirely consisting of cryomorph single-celled cyanobacteria-equivalents that can be found in every geologically active area on the world. Their metabolic functions drive the process of atmospheric renewal.
No other world in the system is known to have native life.
History & Background (Dossier)[edit]

World starport[edit]
Yesup has a Class C Starport, an average quality installation which includes amenities including unrefined fuel for starships, some brokerage services for passengers and cargo, and a variety of ship provisions. There is a shipyard capable of doing maintenance and other kinds of repair. Ports of this classification generally have only a downport, unless this is a trade port or system with an hostile environment mainworld.
World technology level[edit]
Yesup possesses a Technology Level of TL–7.
- Common Communication technologies for this TL include: Early video and early satellite communication networks.
- Common Power Generation technologies for this TL include: Early fuel cells, solar energy, and geothermal power sources.
- Common Transportation technologies for this TL include:
- Land: Improved automobiles, hovercraft, and bullet trains.
- Water: Hydrofoils and early triphibians.
- Air: Hang gliders and supersonic jets.
- Space: Deep space probes and interplanetary spacecraft (System Craft).
World government[edit]
Yesup is governed by a Representative Democracy where government leadership is representatives elected by eligible voters. What determines an eligible voter varies. The representatives determine policy, including selecting members of the bureaucracy. There can be referendum, votes by eligible voters on specific subjects.
