They are bordered on the east by Varnhold and surround the three-hex large Sootscale Kingdom. The Sootscales are kobolds and have access to a silver mine. I've overhead the players mention a couple of times the desire to gain control of the mine.
Explorations currently are taking place to the south and west of the capital, all around the Tuskwater. They've been leaving that area underdeveloped due to their rush to encircle the Sootscales and secure the border with Varnhold. Hopefully by the end of May this year I'll be ready to start book 3 of the series.
Once work slows down for me a little I'll have to see what I can do to get the campaign maps into Campaign Cartographer 3 or something similar to aid in keeping track of the constantly changing maps.
