So I have a game the revolves around the Armada of Evil amassing and invading Cormyr from behind. The Goblin Marches have gain strength and are poised to over run the back half of teh Stormhorns. Now from all the info I have been able to gather there really are not any maps or dicumentations of eth castled/citys on the stormhorn other then HighHorn.
So, I'm embarking on a project to create soem detailed material starting with Huthduth, Eagle Peak, Wyvernhunt, Skull Crag, Old Axe and Finally Greatguant.
If anyone is interested in helping out or critiquing Iam open to suggestion. For now I have a rough of Eagle Peak based on the text descriptions.
Volos guide to Cormyr would give you most of the existing information on settlements and Elminsters Ecology's (the box, not the appendixes)will give you some details about the mountains themselves. You will also find the Goblin Marshes there.
There may be some information in the old Four from Cormyr adventure, but I am not sure. Both the Volo guide and the adventure should be a free download from Wizards page I believe.
