Remus Lupin

Possibly, Allie, but it sounds like this organisation moves people mainly on foot. Some side-along apparation but they're assuming that most of the traffic has to be without it. So short distances, frequent stops. I don't know if we'd want to reveal that we can get wands to their refugees, not just yet. See how things go a time or two. But as I said, I'd bet Galleons they're connected in some way to the group Paul and Lucinda are working with in the north.
