Knight
From Emperor's Hammer Encyclopaedia Imperia
The rank of Knight holds envy among the officers of the territories, and elevation to this rank is truly indicative of when a leader rises from the rest of the membership. This rank can be granted for exceptional service and dedication to the duties required of a Regional or Lieutenant Governor,and is also granted to a Governor General upon appointment. Individuals who have become a "Knight of the Imperial Order" are granted the title "Sir" or "Lady" to be used before their name in all formal communications:
Governor General, Sir John Doe
Governor General, Dame Jane Doe
