Reformated the OP, and added information on the Aeonian League, Dominion of the Northern Marches, Kalthapas Coalition, and the independent settlements of Hammerfall and Keeper's Pass.
Keepers Pass is definitely independent and staying that way for the forseeable future.
Hammerfall on the other hand is now run by BHA. The former Hammerfall folks (Terrabithia et al) left the game some time ago.
Which settlements make up the BHA, do they have a website and contact person?
The BHA settlements are Blackwood Glade, Hammerfall and Brighthaven.
I am not able to speak for BHA on exactly who is in charge of what.
It does seem to change depending on exactly who is active at any given time, Glinder and Fiery both have some level of authority and are potentially good first contacts to get an update on what the current situation is.
