This assume 1.) A castle, and only a castle, is needed to control an area
2.) Castles will only be built in cities.
I disagree with each - most of the descriptions say that the first
STRUCTURE in an area controls it, not just a castle. While I don't know that
a "mine" makes a good seat of government, I think a Tower should be adequate,
and even a house out in the boonies might do fine (not to mention citadels!).
As to #2 - I don't know about you, but I've been considering building a Castle
out in the boonies - there are some nice places to set up shop that are near,
but not in a Town. For example someone could become lord of the Wastlands in
the Resh area, where there are large areas without towns or cities.
BTW, does this also mean that if I build a house in the woods for my men to
huddle under, since it's the first structure I'm now #1 on the hit parade for
opressing the peasants?
