Sestin is a low-population vacuum world, with a population of less than 10,000 sophonts, warranting hazardous environment precautions.
- Life in a vacuum requires great discipline. After all, it only takes one forgotten seal on a vacuum suit to spell death. Those who survive tend to be very methodically-minded and attentive to small detail.
- It is a Non-Aligned world dominated by human sophonts located in the Jerik Subsector of Halcyon Sector.
Astrography and Planetology
This star system is detailed using the Fringian Variant System Description.

System Data
Cardoz-Sestin System
The primary is Cardoz, a dim red subdwarf star. It has a luminosity of 0.004 Sols, a mass of 0.273 Sols, and a diameter of 414,000 km. (I-I) an exotic atmosphere radworld, (I-II) an exotic atmosphere bigworld, (II) an exotic atmosphere radworld, (III-I) a ringed small gas giant: (IIIa) Sestin is its only satellite and is designated the mainworld, and (III-II) a trace atmosphere iceworld form the outer system. Many of the worlds retain satellites.
(III) Rayor
(III) Rayor is a ringed small gas giant that orbits Cardoz at a mean distance of 0.66 AU (98.7 million km), within the outer system, and has an orbital period of 1 year 10 days. It has a diameter of 23,000 km and an atmosphere consisting of 89% hydrogen (H2), 11% helium (He), and less than 1% methane (CH4), carbon monoxide (CO), ammonia (NH3), water vapor (H2O) and other trace gases. It is a pale blue color streaked with high altitude white clouds. It retains a single major satellite.
Satellite
Rayor retains a thin dark ring system and one major satellite:
- (IIIr) Ring System (UWP YR00000-0, extending to 1 Diameter/25,000 km)
- (IIIa) Sestin (designated the mainworld, orbiting at 7 Diameters/161,000 km)
Mainworld Data
(IIIa) Sestin
(IIIa) Sestin is the only major moons of (III) Rayor and is designated the mainworld. It orbits its parent world at a mean distance of 7 diameters (161,000 km), with an orbital period of 11 days 22 hours: it is tidally locked to Rayor. The axial tilt is 6 degrees relative to Rayor. Sestin has a diameter of 885 km, a density of 3.97 g/cm³ and a surface gravity of 0.05 G. Tidal stresses generated by the gravitational pull of Rayor cause occasional geological activity. The atmosphere is rated as Vacuum. The world has no hydrosphere. Mean surface temperature: -156°C.
Mainworld Geography and Topography
Total surface area: 2.46 million km².
Native Lifeforms
Cardoz-Sestin System
No world in the system is known to have native life.
History & Background (Dossier)
No information yet available.
World starport
Sestin has a Class C Starport, an average quality installation which features 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
Sestin possesses a Technology Level of TL–9.
- Common Communication technologies for this TL include: Fiber optics and satellite communication and data networks.
- Common Power Generation technologies for this TL include: Early fusion power.
- Common Transportation technologies for this TL include:
- Land: Ultra high-speed trains and early grav vehicles.
- Water: High efficiency sailcraft, multihulled seacraft, improved artificial gills.
- Air: Tiltrotorcraft, exotic VTOL's, PARWIG, and rocket-assisted suborbitals.
- Space: SSTO spacecraft, early military spacecraft (System Craft), and interstellar STL starships
- FTL: Prototype Jump Drive-1.
World government
Sestin is governed by a Representative Democracy where government leadership is by representatives elected by eligible voters. What determines an eligible voter varies. The representatives determine policy, including selecting members of the bureaucracy. There can be referenda, votes by eligible voters on specific subjects.
