Hiram Drayson was a Human male from Chandrila, known as a military commander and intelligence administrator. Drayson attended an offworld military academy, but returned home with his education incomplete when his father became ill. He took over his father's shipping business; under his leadership, it became the most successful such business in the Chandrila system. Because of this and his partial Academy education, the Chandrilan government made him the head admiral of the Chandrila Defense Fleet. He reorganized it to run more efficiently, cutting down piracy and smuggling dramatically. It was under his capacity as fleet commander that he came to know John Sheridan.
