Well, this can be rather cumbersome, but I'll try to explain the best way you could do it.
If you've already edited Azerbijian as Westeros, then I would replace the name of each State with the name of each of the 7 Kingdoms.
To do this, open the nations.csv file, copy the name of each kingdom (i.e: Westernland, Vale, The North, etc.) and paste it into the STATE field in the world.dat file.
For example:
<STATE id="XXXX" name="
XXXXX" pop="XXXXXX" lid="0" abbr="
XXX">
Replace the name of state "XXXXX" with "Westernland", and the abbreviation with "WST", for instance (chances are the abbr=WES already exists, so I suggest this one just to be safe).
Repeat this procedure within the CITIES field in the world.dat file, for every Westerosi keep/town that you wish to include in your world.
First and last names can be easier.
I suggest making a copy of the first_names.txt and names.txt files included in the game, so you can use the original files as backup.
Once you've done this, open the first_names.csv and names.csv files you d/ld in Excel, copy and paste each name/surname into your copies of the first_names.txt and names.txt files.
Just make sure to follow each name with its proper frequency and nameset (or ethnicity).
Example:
Aaron,1,1
Aash,1,1
Abelar,1,1
Addam,1,1
Adrian,1,1
Aegon,1,1
Etc…
The original .csv files has replaced the "Hispanic" ethnicity with "Westerosi", so you probably want to keep it that way. Just make sure to have the Language ID pct. in line with your ethnicity(es).
Again, this can be painful, given the number of names featured in the .csv file, but once you're done, you should be set and ready to get your Westeros League all set up.
Needless to say, whatever you do,
do NOT forget to backup every single original file from the game.
Hopefully there may be someone who has an easier or quicker way to do this, but I hope this helps.
At any rate, don't forget to let me know how this goes and if you need anything else. Perhaps you can share a QS of the game once you've got it all set up
