"In the halls of the Senate, decisions which shape the destiny of a civilisation are made... and in the dark corridors of these same halls, conspirators work to further their own interests. This expansion puts the spotlight on senators and their influence on the development of your Cities. Each competitor will try to control this influence in order to benefit from favorable decrees or call upon conspirators to try and change the situation. Discover a new type of instant victory, two new Wonders, and much more! Playable with or without the Pantheon expansion."
