By 2222, the Earth Federation was the dominant force in the galaxy. Many of the people who brought about this golden age of prosperity were the winners in the 1st Civil War. Maeve Harrington was now leader of the largest corporation in the Federation. After she married Lwan Eddington (Marshal of the Tech Infantry), there were fears that she would rule the Federation as a kingmaker. To block this, Richard Fox (head of Internal Security), Arthur Clarke (head of the Tech Infantry Special Service), and Samuel Wall (President of the Senate) formed the 2nd Triumvirate and blocked Harrington from Federation politics.
