Penalties for set coordinates?

[skuzzy]

My only experience with them is flying past them but they appeared pretty treacherous from my perspective :) Although there are valleys everywhere. And Mark although it appears you wouldn't want to do that a maybe possible workaround would be to give a single turn plague and create a temporary trait to explain the "disease" as heat exhaustion, etc... although it would have consequence if someone entered the city with it since plague is spread through these means :\
