Well, they didn't announce it, so it's fine. Just call them by their number. I think they will be the same as the city types:

TOWN_HEAVEN = 0
TOWN_PRESERVE = 1; -- Sylvan
TOWN_ACADEMY = 2
TOWN_DUNGEON = 3
TOWN_NECROMANCY = 4
TOWN_INFERNO = 5
TOWN_FORTRESS = 6
TOWN_STRONGHOLD = 7

Regarding the fog, I already said that I have never encountered such a function in my life.
