System Data

Ease-Erena System

The primary is Ease, an ordinary white main sequence star. It has a luminosity of 4.42 Sols, a mass of 1.38 Sols, and a diameter of 2.031 million km. The inner system consists of (I) a vacuum worldlet, (II) a very thin atmosphere inner world, (III) a corrosive atmosphere inferno world, and (IV) a dense atmosphere stormworld. (V) Erena orbits within the habitable zone and is designated the mainworld. (VI) a small gas giant, (VII) a dense rocky planetoid belt, (VIII) a large gas giant, (IX) a trace atmosphere iceworld, and (X) a small ice giant form the outer system. Most of the worlds retain satellites.

Mainworld Data

(V) Erena

(V) Erena is designated the mainworld and orbits Ease at a mean distance of 1.71 AU (255.8 million km), within the habitable zone. It has an orbital period of 1 year 330 days and a rotation period of 19.5 hours. The axial tilt is 16.5 degrees. Erena has a diameter of 16,388 km, a density of 5.97 g/cm³, and a surface gravity of 1.39 G. The world is geologically active. Its atmosphere is rated as Dense, with a mean surface pressure of 2.33 bar and a composition of 79% nitrogen (N₂), 20% oxygen (O₂), and 1% argon (Ar), water vapor (H₂O), carbon dioxide (CO₂), ozone (O₃), neon (Ne) and other trace gases. Approximately 54% of the surface is covered in seas of liquid water: average tidal ranges exceed 0.25m. Mean surface temperature: 24°C. The climate is rated as Temperate-Warm and experiences minor seasonal changes during the local year. The atmosphere is extremely active and violent weather systems, driven by the star and the seas, scour the globe.

Mainworld Size (S)

This world is a Big World between 15,200km and 16,800km in diameter. The world has a standard gravity between 1.1G and 1.5G. The horizon will appear about 5.7km away. Vessels with only 1G of thrust should avoid landing on this world.

Mainworld Atmosphere (A)

This world has a pressure of 1.50 to 2.49 atmospheres. A Dense Atmosphere requires no survival gear although it may be hard on sophonts not accustomed to it.

Mainworld Hydrosphere (H)

This world has 45-55% of its surface covered by liquid water. Wilderness refueling is possible.

Satellites

Erena retains two natural satellites, a cratered vacuum worldlet named Detso and an exotic atmosphere hospitable world named Vuro:

(Va) Detso (UWP YS00000-0, orbiting at 9 Diameters/145,000 km)

(Vb) Vuro (UWP G5A2365-9, orbiting at 45 Diameters/740,000 km)

Mainworld Geography and Topography

Total surface area: 844 million km², Water surface area: 456 million km², Land surface area: 388 million km².

Native Lifeforms

Ease-Erena System

The hot marginally hospitable stormworld lying in orbital position (IV) (within the H– region of the inner system) has primitive extremophile native life, consisting entirely of microscopic cyanobacteria-parallels that thrive in the extremely harsh conditions.

Erena, the mainworld, has extensive, abundant native life, with complex organisms inhabiting every ecological niche. Their metabolic functions drive the process of atmospheric renewal.

No other world in the system is known to have native life.

History & Background (Dossier)

World starport

Erena has a Class B Starport, a good quality installation which includes all the expected amenities including refined fuel for starships, brokerage services for passengers and cargo, and a variety of ship provisions. There is a shipyard capable of doing annual maintenance, overhauls and most kinds of repair, and construction of non-starships. Most ports of this classification have both a Highport and a Downport.

World technology level

Erena 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.
