I don’t list mine but I do know whether say Eileen would like this type of music or another. (In her case, classical. Not got much time for pop though concedes The Beatles’ Eleanor Rigby is “all right”!).
Do your characters’ tastes drive them or do they keep such tastes to themselves?
L’Evallier would never divulge his tastes, except to his wife.
What calms your characters when agitated? What cheers them? What depresses them? What do they get angry about? How well do you know them!!!
Whilst I don’t think you can separate character from plot, both are essential for a good story, a good plot with a weak character will fail as will a good character with not “enough to do” or in the wrong storyline for them. You can only know what story line is right by knowing them well enough.
What is the climate like on your fantasy/sci-fi world? Have the residents wrecked it?
I’ve shown parts of the Fairy Kingdom made barren by having too much magic thrown at them during the magical wars.
How do your characters cope with adverse conditions, adversity in general?
Has the climate shaped your world in terms of geography, history, politics etc (in Britain’s case being an island has helped it in battle if only by getting us to be really good at seamanship)?
What happens to those who damage, deliberately or otherwise, your world’s environment or does nobody care?
Have you got a mental image of what your world is like? I’ve based mine partly on Scotland (!), red rocky areas (Mars!) and part of it has rings around it (Saturn!!!). Magical attitudes to wildlife in my Fairy Kingdom are ambivalent - nobody’s that keen on dragons - but equally Eileen’s been keen to ensure harmless species aren’t wiped out because the sprites get hysterical. So what is the prevalent attitude in your world? What is your environment like?
