The Order would be a major client, if I can reel them in. Churches always are, if they bank at all, but the Order at some point must have been given one of those gifts that the old emperors liked to bestow on the favoured—a string of diamond mines, or mineral rights for the whole of Morocco. When they cashed out I have no idea, but they are now a smallish subset of the Orthodox religion with the kind of money more usually held by people who create search engines or new ways to smuggle heroin.
