Choco: yes they do, they increase production for all 8 fields around them.
Sc0rpio: no Legion alliance around yet
For the world map, the continents are set up in a matrix like this:
_ 0 1 2 3 4
0
1
2
3
4
Each number stands for your town coords. E.g. your town coords are 231:345, this means you are in continent 23 (2xx:3yy). 135:78 means continent 1 (1xx:yy), etc.
You can think of every continent as a cluster, and all the towns really close to you as a galaxy. Traveling from one continent to another requires ships (frigates for troops) and a long time.
edit: just checked, it seems you are all located on continent 51, so it should be easy for you to help each other or trade!
