You are a scion of one of the great noble families of Dranta. Human families who jealously guard their privilege and place in the City of Lights, Drantan nobles have a reputation across the Old World for being eccentric, spoiled, venal, and, above all else, rich. Whether you are a shining example of the reason for this reputation or one who proves the rule by being an exception, people expect things of you when they know your surname and what it means. Your reasons for taking up adventuring likely involve your family in some way: Are you the family rebel, who prefers delving in filthy dungeons to sipping zzar at a ball? Or have you taken up sword or spell on your family's behalf, ensuring that they have someone of renown to see to their legacy? Work with your DM to come up with the family you are part of — there are around seventy-five lineages in Dranta, each with its own financial interests, specialties, and schemes. You might be part of the main line of your family, possibly in line to become its leader one day. Or you might be one of any number of cousins, with less prestige but also less responsibility.
Use the tables for the Noble background in the Player's Handbook as the basis for your traits and motivations, modifying the entries when appropriate to suit your identity as a member of a Drantan family. Like other nobles, you were born and raised in a different world from the one that most folk know — one that grants you privilege but also calls you to fulfill a duty befitting your station. Your bond might be associated with your family alone, or it could be concerned with another noble house that sides with or opposes your own. Your ideal depends to some extent on how you view your role in the family, and how you intend to conduct yourself in the world at large as a representative of your house.
