Wine bottles were opened. Cheering was heard. It was the moment that changed everything.
This may be a slight dramatization, of course, but the point is that the need to breathe new life into these regions is coupled nicely with new fronts in the existing invasions. So players can look forward to regional invasions in the not-so-distant future, pitting player forces against invading armies in new settings that scale for a variety of levels. So now you have a reason to go back to areas you left behind and the invading armies don’t seem like they can only invade spots with the proper invasion paperwork. Everybody wins! Except the residents of the regions being invaded, presumably.
