Thalassa (TR 1613) is a rich water world with a moderate population over a hundred million, but not yet at a billion sophonts in population size.

• Its surface is 90% or more covered in an ocean of water.
• The inhabitants of this world live on the roughly 10% of exposed land mass, in underwater colonies, on city ships, or similar arrangements.
• This is a rich world with a prosperous and thriving world economy.
• This world has high-grade living conditions with a good climate and a non-harmful environment. As such, this world is much sought after with large queues for immigration here.
• Most observers think that the planet's economy and population will prosper in the near future barring outside forces.
• It is a Non-Aligned world dominated by human sophonts located in the Dpres Subsector of Trojan Reach Sector.

Description (Planetology)

The oceans of Thalassa cover the entire planet – the only dry land is an artificial island bearing the planet’s spaceport, and a few tiny islands too small to support any sort of civilization.

History & Background (Dossier)

Thalassa is a rich, non-aligned water world located in the Dpres Subsector of the Trojan Reach.

• The world is rich in life and Thalassan technology is almost entirely organic, using the alien biosphere to support their agriculture and industry.
• Thalassan cities are built on huge floating platforms of woven reeds, some of which are more than twenty kilometers across and support hundreds of thousands of citizens.
• One of the chief Thalassan industries is snail farming. The sea-snails of Thalassa have been bred for size and strength, and grow up to six meters in length. Their shells are water-tight and strong as light steel, and the Thalassans have developed organic compounds allowing them to cut and bond the shell material much as other cultures cut or weld metal.
• Various forms of seaweed are cultivated for use as plastics, clothing, food or medicine.
• They mine the asteroids and moons for vital metals, and trade with other worlds.
• One key technology the Thalassans obtained from the world of Neumann was a genetic modification allowing humans to breathe underwater.

World Starport (St)

Thalassa 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 Government

• The Thalassan government is made up of a series of councils, each overseeing a particular aspect of Thalassan society.
• Membership on a council is given to those best suited to it – a Thalassan may apply for membership when an opening arises, and is given a grueling series of exams and tests. Only the best and most suited serve on the councils, and even being accepted for testing is a huge honor.
• The most important council is the Council of Cycles.

Council of Cycles

As the cities of Thalassa drift on currents at different speeds and in different directions, correctly calculating where each city will be and how it should interact with its neighbors is vital. A city in the doldrums might run low on food, so the Council of Cycles will arrange for food to be transferred along a chain of cities to one which will soon drift near the stranded community. The Council of Cycles effectively specializes in using weather and the mechanics of currents to optimize the planetary economy.
