COA Hamm

Hamm is the barony of Freixenet, and presumably located somewhere within Verden, though this is not elaborated anywhere in the novels or short stories. What is known is that the people there still speak of the time the witcher liberated the baron from a curse which had turned him into a cormorant, though later recountings of the tale say he was turned into a swan, along with ten brothers.
