Captain Bree is here at the request of the Coalition of Free Cities to provide additional security and represent the interests of the free mercenary companies that operate within the realms. He also has the confidence of the Merchants Guild and is speaking for their interest within the diplomatic sessions. This is surprising since Captain Bree was recently brought up on charges by the Merchant's Guild and nearly executed. The sentance was dismissed as a misunderstanding after some sort of deal was struck between Bree, the Black Exchange and the Nobles of Vithyr.
