Kraina Pod Wulkanem. 3 maps that were done at different time each. The last one, here, is a color reference. There are more maps, that shows territories, new names/terms or changes that happened after the story, also maps that in detail describes floors in caves, past history of the KpW, maps of other places than KpW or generic map of the continent. But they contain too much spoilers. All of those maps are couple years old, the most present is like 5 years old.
I have post with conceptual views on some details in KpW: http://twarda.tumblr.com/post/10884019359/zzii-concept-illustrations-and-flora-reference
