Eric's point was this:
On the 3E map, it looks like this (apologies for the arrows, they have no bearing on the point. I'm being cheap and borrowing someone else's image:
From this, it doesn't look like there's a whole heap of stuff between Lathe and, say, Redmoon or the Bay of Kings. However, there's over 400 miles, further to the other parts of the Cinder Isles. This is quite a bit of space for things to exist in.
This gives me two things to think about:
1) On the one hand, given the way the books are written, I was immediately struck with "the Bronze Tide are close to Lathe" because of the way the map is. Am I misreading the books, or is there some missing impression of things in between the two?
2) How do you handle this as an ST? If you've got a travelling party, and it's meant to have multiple powers detailed within that space, how do you conjure up that variety if (say) your party is travelling from Goldenseal to Dajaz, without spending your entire existence homebrewing small Southwestern kingdoms/nations, while still giving them the weight to leave that impression on the players?
