Magnus nods. "My point exactly. We're just breaking even as it is. If we add another magus and another set of buildings, with associated servants, lab expenses, and the like, we'll start losing money. We have some cash on hand, so we could afford that in the short term. But it's not a long-term solution. That's one reason I raised the issue of getting people here. Almost all of the ideas I have for raising our income require people. Trade needs sailors and ships; farming needs farmers; sheep herding needs shepherds; mining needs miners; forestry needs foresters. Until we have people, we're unlikely to have much in the way of income. We could sell vis, I suppose. But I'm loathe to do that for obvious reasons."
"Of course, we can't afford not to accept Atticus either. The loss of Nigrisaxa's contributions would be as bad, or worse, as supporting a new magus. Besides, we do want to recruit magi for the island."
"The solution, as I see it, is that we start focusing on recruiting significant numbers of people to the islands, and getting some money flowing into our coffers. With money we can expand, and with expansion we'll have more opportunities to make money. The process will hopefully build on itself."
"And Atolycus is right about the need for the cantons to support Domus Magi. There's enough land dedicated to the central covenant for it to feed itself. But it will definitely need more income than that to perform the duties of a central government. Some support from the cantons will be required."
Transforming Mythic Europe has this to say about income:
The real question is, what are "expenses" for a manor? I'd say between 10-15 pounds, depending upon how ambitious you are. For now, I'll say it's 10 pounds, so each manor will get you 10 pounds/year in income after expenses. This number may vary in the future. Magic assistance may allow for some inflation of numbers.
This will cover various types of farming income. If you want to explore a different income source, then we'll develop that as seems right.
