As to the merchants, there are merchant in fort Vehl. Have a look there.
I do understand that I can use the merchants and such in Vehl, and I have been. Merchants, etc, was not actually my point of issue, rather the what and where I am allowed to be, and in what form I can do that without breaking steadfast rules. I see now that not all the rules are steadfast, as long as I RP my away round them. I guess I need to think more outside the box, while trying also to stay in it, so to speak.
