Empyria A

The inner most world of the Empyria system is a hot dry world similar to most terrestrial worlds close to the parent star.  The world does have a few small mining colonies which operate during the long 40 day nights on the planet.  Much of the planet is rich in titanium meaning that mining is very profitable.

Empyria B

Empyria B is a small earth sized world rare for this type of planet, a cloudy world with a thick atmosphere that turns into a global ocean.  Though these planets are somewhat common expect they are usually super earths.  Pressure at the surface is much too high, and for that reason it was believed that the planet was unlivable despite being the right temperature and size.  A solution was found though, large platforms were built on the surface that rose above the clouds where the atmosphere was thinner and more earthlike, entire cities were built on these platforms capable of supporting millions.  Empyria B is one of the most beautiful and unique worlds in the galaxy, with large cities sitting within the clouds.

Empyria C

Empyria C is an icy world sitting at Mars like temperatures.  The planet is often times considered a good candidate for terraforming, expect that the planet is fairly dry and large amounts of water would have to be brought in from elsewhere (most likely comets).  The planet has a thin atmosphere of carbon dioxide.

Empyria D

Cold small world roughly the size of Ganymede.  Empyria D contains large amounts of sulfur on the surface and in the thin atmosphere left over from a recent highly volcanic period.  The sulfur acts as a greenhouse gas keeping the planet warmer than it would normally be.  The planet is used primarily as a base for mining colonies established in the nearby asteroid belt.

Empyria E

Empyria E is a stormy, windy, hydrogen helium gas giant.  The planet is the largest body in the solar system.  A substantial amount of helium-3 exists deep below the clouds and is very difficult to mine.
