Glossary of Terms and Proper Nouns from the books.
Black Dagger Brotherhood (pr. n.) Highly trained vampire warriors who protect their species against the Lessening Society. As a result of selective breeding within the race, brothers possess immense physical and mental strength as well as rapid healing capabilities. They are not siblings for the most part, and are inducted into the brotherhood upon nomination by the brothers. Aggressive, self-reliant, and secretive by nature, they exist apart from civilians, having little contact with members of the other classes except when they need to feed. They are the subjects of legend and the objects of reverence within the vampire world. They may be killed only by the most serious wounds, e.g., a gunshot or stab to the heart, etc.
blood slave (n.) Male or female vampire who has been subjugated to serve the blood needs of another. The practice of keeping blood slaves has largely been discontinued, though it has not been outlawed.
the Chosen (n.) Female vampires who have been bred to serve the Scribe Virgin. They are considered members of the aristocracy, though they are spiritually rather than temporally focused. They have little to no interaction with males, but can be mated to warriors at the Scribe Virgin's direction to propagate their class. They have the ability to prognosticate. In the past, they were used to meet the blood needs of unmated members of the brotherhood, but that practice has been abandoned by the brothers.
doggen (n.) Member of the servant class within the vampire world. Doggens have old, conservative traditions about service to their superiors, following a formal code of dress and behavior. They are able to go out during the day, but they age relatively quickly. Life expectancy is approximately five hundred years.
the Fade (pr. n.) Non-temporal realm where the dead reunite with their loved ones and pass eternity.
First Family (pr. n.) The king and queen of the vampires, and any children they may have.
hellren (n.) Male vampire who has been mated to a female. Males may take more than one female as mate.
leelan (n.) A term of endearment loosely translated as "dearest one."
lesser (n.) De-souled human who targets vampires for extermination as a member of the Lessening Society. Lessers myst be stabbed through the chest in order to be killed; otherwise they are ageless. They do not eat or drink and are impotent. Over time, their hair, skin, and irises lose pigmentation until they are blond, blushless, and pale-eyed. They smell like baby powder. Inducted into the society by the Omega, they retain a ceramic jar thereafter into which their heart was placed after it was removed.
needing period (n.) Female vampire's time of fertility, generally lasting for two days and accompanied by intense sexual cravings. Occurs approximately five years after a female's transition and then once a decade thereafter. All males respond to some degree if they are around a female in her need. It can be a dangerous time, with conflicts and fights breaking out between competing males, particularly if the female is not mated.
