Well its the location of the American operations on Mars. I am trying to get a good plot hook that was found there that directed the US to concentrate its Exploration to what would become the American Arm. I don't want it to be powerful but more of something that opens up alot of questions and adventures that would link what Colin did for the Beta Aquila cluster. One of the idea I have is something simmilar to the Zhodani map projector to the core. Any good ideas?
