Honor loathes coffee and considers hot cocoa far superior.
She owns and practices with a replica Colt M1911 .45 caliber semiautomatic pistol, a weapon considered to be an anachronistic "hand cannon" by her contemporaries, who prefer pulsers, which fire small-calibre darts at extremely high velocity using a gravitic propulsion system. She acquired a taste for obsolete handarms from her uncle, Jacques Chou, who is an active member of the Society for Creative Anachronism. His training made her a pistol expert (useful on Sphinx outside its protected areas, given its native predators).
She also wears an eyepatch from time to time, due to the loss of her left eye while defending Protector Benjamin Mayhew from an assassination attempt. Normally she uses a prosthetic eye, though on occasion it has been disabled (as when she was captured and transported to Hades). Additionally, some of the nerves on the left side of her face were damaged during the same incident, and were replaced with natural-looking circuitry.
She lost her left arm during the escape from the Tepes and had it replaced by a cybernetic arm which, among other interesting features, contains a hidden pulser pistol inside the index finger, a weapon which has saved her life on at least one occasion.
Honor practices a fictional martial art known as coup de vitesse (French for blow of speed). This is a fusion of several western and Oriental martial arts, where emphasis is placed on offense at the expense of defense, resulting in a very brutal and effective style. As of War of Honor, Honor has earned an eighth level black belt. There is only one higher rank. Her proficiency has saved her and others several times.
Honor has become proficient with the Grayson style of swordplay, involving a blade very similar to the katana, which by a quirk of history is used ceremonially by Steadholders and is the center of a martial art on Grayson.
