Just a suggestion, but could it be possible for a vendor in the Drain to sell more crafting items? I'm thinking specifically Charcoal ( only one vendor in barovia known, will not sell to outcast races), but there might be other ones.
I'd say that they sell it at a severe mark-up, though, like mayhaps thrice the regular price of it or more? That way, people can still RP using proxies to buy it, if they wish for it, but they can still buy it if they can't or don't want to rp something like such out.
