Lord/Lady

A person of Nobility, whether inherited or earned, be it a Baron/Baroness, a Duke, or even a commoner who has acquired enough wealth to be given a charge of land.

This title is considered the lowest among "civilized" people, as most with this title have been disgraced or impoverished former Baron/Baroness or other landholder.

While it is used as a "catch-all" for any title, those with a Barony or higher don't introduce themselves as a mere "Lord" be it out of pride or out of dutifulness.
