What's the larger cosmology? Is the existence of some sort of "standard pantheon" an acknowledged fact, or does each culture have its own pantheon? Are there any strong differences of power between the deities? Do these deities have their own "home planes" that mortals might be able to visit even before their deaths, or is whatever happens after death a mystery? And are there some eldritch entities in the vein of Lovecraftian Great Old Ones?

And what's the prehistory of the setting? Is the world a relatively recent creation, or is it millions or billions of years old? And even if it is humanocentric now, did it have ancient prehuman civilizations which might have left remnants and artifacts behind?
