I have a question concerning the Jovian league. If someone else wants one of the moons around saturn or jupiter you're willing to accommodate right?Also you might wanna think of what lives under the ice sheets of Europa.

That will depend entirely on what the person wants with a specific moon. There are a few that are off limits for a other player to claim as a nation as they are important to my nations structure,

These are;

Io- which is a large resource moon, holding a few subsidiary mining and refining corporations. The nature of the moon makes for surface facilities being very uncommon and overly dangerous so most facilities are on orbital structures with only the heavy machinery operating on the surface.

Ganymede- The Technical capitol of the Jovian league. As it has water and oxygen, it will have some prior life, although its very primitive fauna, like ultra early grass. 
Using those plants and a little space magic, the world thrives on food made from those plants that, after being treated with said space magic, The planet, through space magic as well, has been entirely Terra-formed. I'll probably throw some epic space bs and say that greenhouse gasses and solar panel focusing arrays have made the planet warm enough for people to have open air cities (earth-like) but there are many MANY underground colonies and emergency subways from before it had an atmosphere. 
Note: The world no longer needs the solar panels to stay warm as the gasses are already at safe levels to keep heat levels although they are still there and function to keep the present temperature (space magic)

Europa- The first colonies in the Jovian region were to Europa and now the surface is littered with giant oil-derrick like platforms with large stilts reaching far into the surface below. The under water parts contains space whales and primitive fish. The first creatures to actually be discovered that are that advanced! (can be changed) The atmosphere hasn't been changed much so that the entire planet doesn't lose its nature. So the air, though breathable, is very cold and windy. (think Antarctica) so many areas have focused solar panels to warm open air colonies and others are entirely enclosed. this planet houses many space elevators to the space stations that began the Jovian league. Many space ports exist and the Jovian main fleet operates from there. 

Callisto- Kind of.. well, I'm juggling ideas of it being another industrial world and trade place. Seeing as its the furthest out, it'd have various orbital military bases but due to its proposed interior, I do not think it'd be Terra-formed at all. Just surface and subsurface enclosed colonies.

Metis- A giant... giant gas refining planet. Few enclosed colonies but quite a few giant orbital ones, both residential and industrial. It is the biggest one and also has one of the biggest military bases (Entire Jovian 2nd fleet guards this place as its vital to the Leagues economy.)

Adrastea, Amalthea, and Thebe- The other inner planetoids that operate similar to Metis but on a much smaller scale. The Jovian 6th fleet defends these.

Various other moons function as research worlds (both civilian and military) outer colonies or trade ports for nearby colonized moons. I'm thinking one or two are kind of Terra-formed using the panel and green house space magic but these would require constant solar energy to maintain heat. 

These worlds are all called, no way around it. If people want factions on those worlds, by all means let me know (it's likely to be accepted as I intend the Jovian region to be a... dangerous.. place to live.) If people want to use one of the smaller asteroids for what ever purpose, that's fine but having a full blown military faction within the Jupiter region is a no go as the League navy would squash it without a thought. (like highlander, there can be only one!)

I'll make another post regarding Saturn soon but I'd go ahead and consider most large moons off limits but I'm not sure yet. Jupiter is the primary Jovian league stranglehold as its seat of government, main navy yards and HQ, and the biggest exporter of high end gases/fuels etc.
