Commerce
This a master page to talk about how intraplanetary and interplanetary commerce works in the various multiplanetary nations. Smaller polities, like the Faulfenza and the Eldritch, can have commerce sections on their world pages.
Alliance
Overview
A discussion of how business operate in the Alliance, what it takes to start one, how intergalactic versus planetary trade works, etc.
Governmental
This is where things like taxation, currency (and currency exchanges), intergalactic banking and shipping would go. I believe there's some talk in "Dark Lighthouse" about Pad relay stations used for cargo shipments, that kind of thing would go here.
Cultural Influences
Needs a better title, but basically this is where 'the Pelted like local businesses' or 'the Eldritch prefer handcrafts' would go. These are the assumptions baked in at the inception of the Alliance that have influenced the four hundred years of progress after.
Chatcaavan Empire
Not sure how much I've talked about business or money in the various Chatcaavan stories, but at very least some discussion of Outside in relation to businesses would go here, for the Throneworld.
