Entertainers do exist amongst the noble classes but choosing that as a profession would equate to following a profession that's somewhat 'below' one's standing. For a female character, then there wouldn't be the same sort of stigma as for a male, so that exquisite geisha is a good intepretation of the class at that cultural level.
- Lastly, and I'm sure this has already been pointed out by some readers, the skill of "Courtesy" is always mentioned as a Basic Skill in the char-gen chapter (ppg. 38-41), however the standard RQ character sheet never lists it as such, and the RQ Companion first introduced it as an Advanced Skill. There are no numerical mistakes, and no damage done to the game system, but I just thought that the Basic Skill/Advanced Skill distinction might confuse a new player.
Yes, all characters have Courtesy as a basic skill; is not considered an advanced skill, but something all Japanese characters have, and are trained in, from birth.
