The Commerce Guild will be a large part of your journey towards building the best workshop you possibly can, and is the primary focus for acquiring commissions, buying and selling resources, earning money, and tracking your workshop rank compared to that of your competitors.
Mission Statement Edit
It appears that each of the Free Cities have their own branch of the Commerce Guild.
Portia Branch Edit
Antoine is the guild's secretary; you will turn your commissions in to him once completed, and he will dole out your reward and assign you your ranking points.
Your Competition Edit
Your biggest competition in achieving that coveted top-ranking S grade spot on the builder leaderboards is Higgins, and for good reason. Despite his arguably underhanded tactics, such as sometimes accepting more than one commission a day even though this is against guild policy, he is cited as a hard worker who is devoted to being the best. Higgins will maintain the top rank on the leaderboards unless you can overtake him.
