The area of Iobaria (which I think is technically Casmaron) just to the east of Brevoy is covered in AP 33 (Kingmaker 3; The Varnhold Vanishing).
The area to the east of that, the Dvezda Marches, is covered in AP 69 (Reign of Winter 3; Maiden, Mother, Crone).
Some of the action takes place in the city Neruzavin in the Parchlands, in AP 113 (Strange Aeons 5; What Grows Within).
There might be more information in stand-alone modules, or areas described in Campaign Setting sourcebooks.
