Now combine that trading range with the ability of a steward/lord, who can always trade with his home region regardless of where they are. You can be *very* effective.
"cooperative lords" is the element in the equation I'm disliking. Given how realms with their adjacent unclaimed regions can cover quite large areas, that means that trade can severely be hampered by mere non-cooperation, whereas before it would have taken them active measures to block it.
The ability to have a steward trader go far far away is appealing... if only I had a trader as a knight (heck, a knight at all).
