The Mercantile Council of Yanmass is the advising group to Baron Kustios. During his illness, they are essentially the de facto rulers of the city. Made up of 20 members, 6 primary and 14 secondary members, who are all influential merchants and businesspeople. The primary members all have a single vote on the council, while the secondary members have no vote, but are allowed to speak at the meetings and bring issues to be debated and voted on. They also serve as a way to keep the deliberations of the council public, as while the meetings are not open to the public, the secondary members may bring one guest each.
The current primary council members are the six richest Taldan merchants, and while ostensibly they are all equals, they are usually led by the richest one. The high priest of the church of Abadar traditionally has a seat as well.
