In relation to Drezen and other places in/near the Worldwound?
Inner Sea World Guide.
If you do an image search on Google for Kenabres, you can find a map of Mendev that shows where Kenabres is. Also, the Inner sea map (which is in free downloads) shows Kenabres.
This was the greatest disappointment of the map of the Worldwound in the map portfolio rendering it almost useless. It does not show Kenebras or any of the rather important features just outside the borders
