The perfectionist and linguistics nerd in me wants to point out that "Urbis Phobia" means "fear of the city" (= being afraid of the city). If you want "City of Fear," it would be "Urbs Phobiae." But maybe that's not what you meant, and maybe it doesn't matter anyway. Maybe the best results come from unplanned little slipups. I will try to emulate your mood of quiet happiness with the product.
I enjoyed that post about Latin grammar. The aliens in my fiction spoke broken Latin and other languages monitored
from Earth over the ages. Then my hero was told, in a salop way, that the main issue was to live in "cities of fear" or
"places filled with anxiety" which refers to their ongoing state of civil war. It is very loosely based on the first Valerian
comic. Also an evil headgame, played by hidden leaders of alien planets upon the minds of human prisoners. It
is more or less a vague concept, coming from alien minds. Latin as filtered through quantum computers designed
long ago, far away. We are now checking out Squares of the City, by Brunner from 1965.
