The Brosen Royal Guild is the guild controlled by Eriene Mierelen, Duchess of Brosengae. She is the company's sole owner and she runs her company as she does her duchy, though she has had more success with her commercial operations than with her own country, controlling all the trade in Brosengae and having significant interests in both Avanil and Tuornen.
