Ferris ruled the Ferris Dominion and the American Empire. According to Khan Noonien Singh during his 2259 trial, Ferris "bled" her empire dry monetarially for her own fortune. She also sent armies to battle the New American Empire in the lands that were formerly Mexico. (ST reference: Federation: The First 150 Years, TOS - Khan comics: "Issue 2", "Issue 3")
- The Star Trek: Khan comic book series depicts Ferris as in charge of the Ferris Dominion in South America and at war with the New American Empire; Federation: The First 150 Years depicts Ferris as in charge of the American Empire. It is possible that at some point Ferris took over the (New) American Empire.
