So how are the arts treated in your own fictional worlds? Do they have a therapeutic value and, if so, who benefits the most from this? What impact does this have on the society you have created (and also on the characters concerned)?
Or are the arts treated with contempt, something indulged in privately and quietly? (To me a world like that would be very bleak. Could that bleakness continue or would someone find a way of challenging it and breaking it down?).
How important are stories to your characters and your fictional world? Are there "authorised" versions and who dictated they should be the official stories put out for the public? Who can enjoy the arts? Are there restrictions (on terms of the cost of taking part or moral objections)?
I can't imagine any world without some sort of art, even if it is suppressed, but what importance is given to it could lead to a range of stories.
