A quote from my solo campaign that really got me thinking about how players perceive Npcs.
Does your players treat your precious Npcs like nothing but obstacles, exploits and cannon fodder, whether they are gelatinous cubes or humans?
And if so, what can we do to change it?
At regular intervals, a god takes control of your world's weather. Choose the gods at random each turn of the interval and begin applying their effects subtly. Their power will depend on the strength of those who worship them.
For civilised people, worship of a god actually wanes during that god's month in an effort to reduce their potential destructive effect.
