Mainworld Data

No information yet available.

Mainworld Size (S)

Tethys is a Meso World between 12,000km and 13,500km in diameter. The world has a standard gravity between 0.8G and 1.1G. The horizon will appear about 5.1km away. Vessels with 1G of thrust should check with local starport authorities before attempting to land using emergency power.

Mainworld Atmosphere (A)

Tethys has a pressure of 1.50 to 2.49 atmospheres. While a Dense Atmosphere requires no survival gear this atmosphere also contains an unusual taint such as such as disease, a hazardous gas mix, pollutants, or sulfur compounds which requires the use of a Filter Mask. Some taints may require more protective equipment. TL–3 or more advanced survival gear is required to settle this world.

Mainworld Hydrosphere (H)

Tethys has 95-100% of its surface covered by liquid water with only a few islands and archipelagos. Wilderness refueling is possible. Such worlds are Water Worlds or Ocean Worlds.

Mainworld Geography & Topography

Native Lifeforms

Native Sophont : Hamaran

Homeworld of the Hamaran, Tethys is today considered sacred and only the Haja'qi (priests of racial knowledge) are allowed to dwell upon its surface. Each year millions of Hamaran and humans come in pilgrimage to visit the beautifully preserved buildings and temples and to taste the sea. Most Hamaran consider it their sacred duty to visit Tethys at least once before they die.

History and Background

A population of humans and other interstellars maintains the starport.

Tä Husa Hiä, the 23rd Tä Gyasu (prophet) led the Hamaran exodus from Tethys during the Ushran War.

World Starport (St)

Tethys 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.
