Star System
Distant from Earth, the Eos-system was sparsely colonised during the Star League Era.
Star “Eos”
Eos is an F8V star, much brighter and more white than Sol.
Inner System
Selene
The closest planet Selene is a large mercurial world wracked by volcanic activity and hemmed in by an Asteroid belt (itself home to a dwarf terrestrial).
Hecate
Hecate is the major force on the Eos system with a population of 166 million souls – though it has moderately advanced technology, it has a low level of industrial development and output, poor agricultural dependence due to the very cold climate.
Like most planets in the Eos system it is self-sufficient for raw materials, but with low surface water and a tainted atmosphere.
Originally a Star League-era colony, it is now controlled by an oligarchic pseudo-democracy.
Pan
Aa large terrestrial world with a high temperature and toxic atmosphere, with an Earth-like day/year and gravity. It is home to a small population of colonists who have declared independence from Hecate and live as a socialist-anarchist commune at the very bottom of the technological and industrial barometer.
Janus
Janus is home to the oldest colony in the system, founded before the Star League, and the original abandoned colony remains.
With a population of 22.5m and a democratic government, Janus has the potential to be a great force with a breathable atmosphere, abundant surface water – and though agriculturally self sufficient, with such a low population it has an extremely limited industrial base.
Outer System
Further out are the two ringed hydrogen/helium gas giants of the system, Proteus and Morpheus. Morpheus plays host to moon of considerable size, not yet investigated – and an abandoned Star League space station.
On the periphery of the system are two terrestrials, Erebus and Nyx – home to nothing but viral lifeforms in the near vacuum at close to absolute zero.
