The court of the Prince is the extended household and all those who regularly attended on the prince. Members of the court are called courtiers.
These courtiers include Prince's retinue and household, and those with court appointments such as the Seneschal, Sheriff or Scourge. Members of the Primogen are not technically part of the court, though they often enjoy the same level of access to the prince as do courtiers.
