So what trials of life does your fictional world face and how does it handle them? Are the trials a threat to the world's existence or irritants that everyone has learned to live with (probably because it is too much hassle to remove them altogether)?
Are the trials of life those things that inevitably come about as a result of the way your world is organized or because others abuse their talents/skills to the detriment of others? And how do they abuse those talents/skills? What stops them getting away with it?
Do the trials of life reflect the weaknesses of your fictional world and is it, via its characters, aware of that?
