Thanks Valkaun! That was my purpose, to flesh out the Goldchasm, but to leave room for other DM's to detail it as they wish.
I'm planning to give more details about the Stonehammers and Oakleaves in up coming Cannonfire articles. I don't know if anyone else would be interested in them since I'm making them up for my campaign, but I decided to share them anyway.
