Somebody posted a useful map of the Kingmaker maps posted over the map of the River Kingdoms. From that I created my own map of Pitax. It comes to a total of 127 hexs including Mormouth and Sarain.
I would limit Pitax to two or three districts. Mormouth should also be bigger because it was once the capital of Corvenn and so there will quite a lot of ruined or dilapidated buildings which can be revived.
The state would have one or two quarries at most and no mines according to the River Kingdoms Guide. It should have a lot of farmland with quite a number of agricultural resource hexs representing the vineyards around Sarain and the orchards between Sarain and Pitax.
I have a new group that have never played Kingmaker, so I've had to reread all of these good nuggets. Thanks again all for sharing.
