Seing as this is becoming a topic that needs to be spun off yet again, I will bring it back to the OPs intent.
When walking through Badside (outside of Pavis), I would imagine the smell of open sewage, rotting meats, body odours of people and animals pressed too closely. Apple Lane in Sea Season should be redolent in the smell of apple blossoms, possibly something sublime. And arriving in Autumn to scent the freshly baked apple pies in windows and pouring forth from the Tin Inn! Entering this fine establishment might cause the weaker to swoon. Dagori Inkarth, the mind boggles at the possible smells here... I can not even imagine the smells never mind describing them,
and the dissonance that would cause in a mixed party of Uz (that name truly works in this discussion) and human. I will leave that to folk with better imaginations and vocabularies than I. Hmm, I am thinking a thesaurus might be the GMs best friend here.
