So, i've checked the rules a bit, and I'm a little lost on what parts of the map represent.
For example, there is the GREY Diamonds, labeled 1-10, what is their purpose?
And the Solar map representation on the far right. What is the purpoase of all the +6's, as well as the two +0's?
If there is one particular rule book where this is explained in depth, I would much appreciate the info!
