IIRC, the homelands are moddable. there was an old thread on that.

it was kinda convoluted though based upon a region number system and faction number system that had to be worked out and a big thing on unformatted text.

turns out that \\ or // can be used as line breaks or comments or something.

my memory may not serve that well.

ask Wes or someone else. they were in the thread.
