New sea
So I’ve been playing this game for a while now and I’ve always thought that the bottom of calm waters always looked kinda empty, with portals being on all sides but the bottom I think that would be a perfect place for a new sea, and since it would be a new area there could be a Greek/roman civilization with triremes and a distinct Greek theme. And I know this probably will not happen because of the whole making a whole new map/culture/faction but it could be something to make if the devs run out of ideas.
