I think that a mountain side village would be the coolest base ever. It's simple and I think there wouldn't be that much of a need for a lot of primmy structures. I suppose the story would be a dispatch of the Imperator's forces to pacify a town and set up an HQ while marauding military factions would try to lunge at us... or something. I JUST WANT A BUNCH OF TREES AND AWESOME TERRA-FORMING!!
