Your civilization's influence is represented by the Influence Discs in your player color. Influence Discs are used to mark the Sectors your civilization Controls. Also, each Action you take requires you to move an Influence Disc from your Influence Track to the corresponding Action Space. The leftmost Influence Disc is always used when Influence Discs are moved from your Influence Track. When Influence Discs are moved to your Influence Track, they are always placed on the rightmost available space. The rightmost empty space on the Influence Track shows how much Money you have to Pay at the end of the Round to keep your civilization functioning (in the picture below, 2 Money ). Thus, the more Sectors you Control and Actions you take, the more Money you need to maintain your civilization.
