Pyrrn is a poor, low-population desert world with a population of less than 10,000 sophonts.
- This world has no free-standing water.
- It is a Non-Aligned world dominated by human sophonts located in the Farin Subsector of Halcyon Sector.

System data
The primary is Arryn, a gigantic red giant star. It has a luminosity of 832 Sols, a mass of 6.52 Sols and a diameter of 133.6 million km – the corona extends as far as 0.44 AU, beyond orbital position (II). The inner system consists of (III) a sparse stony planetoid belt, (VI, VII) two rocky vacuum worlds, and (VIII) a large thin atmosphere world – orbital positions (IV) and (V) are empty. (IX) Pyrrn orbits within the habitable zone and is designated the mainworld. (X) a large exotic atmosphere world and (XI, XII) two small icy worlds form the outer system. Many of the larger worlds retain satellites.
(IX) Pyrrn
(IX) Pyrrn is designated the mainworld and orbits Arryn at a mean distance of 24.5 AU (3.67 billion km), within the habitable zone. It has an orbital period of 47 years 180 days and a rotation period of 18.5 hours. The axial tilt is 16 degrees. Pyrrn has a diameter of 8,320 km, a density of 5.87 g/cm³, and a surface gravity of 0.69 G. It is flexed by the tidal effects of the primary and of its moons and is geologically active. The atmosphere is rated as Thin, with a mean surface pressure of 0.46 bar and a composition of 82% nitrogen, 17% oxygen, and 1% argon, carbon dioxide, neon and other trace gases. Approximately 4% of the surface is covered in lakes of liquid water. Mean surface temperature: 67°C. The atmosphere is dynamic and powerful weather systems, driven by the star, sweep across the globe. The climate is seasonal and weather patterns follow regular cycles during the local year.
Satellites:
Pyrrn retains three natural satellites, all small vacuum worlds:
- (IXa) Ember (UWP Y100000-0, orbits at 9 Diameters/75,000 km)
- (IXb) Smutt (UWP YS00000-0, orbits at 11 Diameters/92,000 km)
- (IXc) Furniss (UWP H200000-0, orbits at 45 Diameters/375,000 km)
Mainworld geography and topography
Total surface area: 217 million km², Land surface area: 208 million km², Water surface area: 9 million km².
Native lifeforms
Pyrrn has extensive native life. Flora is extremely hardy and capable of surviving in very marginal environments: the dominant species have extremely long interconnected networks of roots and are able to access water from very deep aquifers. The flora has a tendency towards very short stems and small clusters of flat waxy leaves: foliage is generally dark greyish-green in colour. Their metabolic functions power the process of atmospheric renewal. Almost all fauna is small, massing no more than 1 kg, and live subterranean existences among the deep roots.
History & Background (Dossier)
No information yet available.
World starport
Pyrrn has a Class D Starport, a poor quality installation which has few of the expected amenities. There is unrefined fuel for starships and a limited variety of ship provisions. There is no shipyard of any kind, but there may be parts and technical support for doing minor services and repair. Ports of this classification generally consist of only a downport, unless this is a trade port or system with an hostile environment mainworld.
World technology level
Pyrrn possesses a Technology Level of TL–6.
- Common Communication technologies for this TL include: Telephone, radio, and television.
- Common Power Generation technologies for this TL include: Early fission power generation, advanced water and wind generation of electricity.
- Common Transportation technologies for this TL include:
- Land: Improved automobiles, early ATV's, and dedicated AFV's.
- Water: Amphibious vehicles, improved submersibles, and early SCUBA gear.
- Air: Early jet aircraft and rotorcraft VTOL's.
- Space: Early unmanned rocket delivery systems and early manned orbital rockets.
World government
Pyrrn is governed by Self-Perpetuating Oligarchy. A single family or small group provides the leadership and important positions in the government. These positions are inherited by member of the group or their family members. The organization may be a monarchy, with titles passed to family members, or a plutocracy where inheritance of the family fortune includes government position. Alternatively, the organization may be a more typical government apparatus, only with positions of power inherited.
