Merlin nods, clearly impressed with your thoughts.
"Copying a magic potion is a lot more difficult than, say, an herbal remedy or a flagon of ale; the magical properties are not really in the physical formulation. However, we can probably find a way to do that."
"The wolves all teleport, and that's their advantage. As far as I know, they do it in much the same way we do, by bringing into focus in their mind a unique place to which they wish to travel and walking the twilight to get there. Some of them are very good at it, and most of the rest rely on the best to get them where they need to be. So the best way to become that good is to practice that much."
"Four per village? That will be simple enough in some places, but there are villages in which fewer than a dozen people live in the village. There are, of course, farmers and shepherds scattered around them who consider that the center of their community, but some of them won't see the village save on Sunday. But I understand your sense: a few people in each of many places."
"I don't know that we can guarantee immunity to someone, but I think that becoming a ghoul is a temptation, that is, no one is forced to become a ghoul and no one can become a ghoul without choosing to seek the power and immortality of the undead. That is a risk in your plan generally, though--will we be able to recognize those who will not be tempted to seek that power, and particularly not tempted to seek it once they have had a taste of the power you are offering? But that's something we'll have to do our best with. As to mind control, we can make them more resistant, but again there is no absolute guarantee on that, only an increased strength to fight against it."
"So, it seems we have a few tasks to tackle--developing a few spells, copying your potion, and finding the right first group. Do you want us to tackle these in order, or split up and each take a task?"
