Diamond Lake is a large mining town on the shores of Diamond Lake (Lake) It is run primarily by lesser nobility and rich merchants who own the Mines that employ the majority of the population. It started the campaign as a rather unsavory place, but it quickly becoming more Neutral Good-ish. Originally from the Age of Worms adventure path, the path has been discarded.
Diamond Lake is also known for the large number of mostly forgotten tombs in the forests nearby.
Recently, an Adventurers Guild has been established, funded by a rich former adventurer from Senate’s Landing, also known (previously) as the Free City.
