The challenge, is that one needs to convert vis to silver. Doing it through Redcaps is inefficient, and incurs rather large exchange rates. While it isn't widely known that Mons Electi has cash flow problems, it's not too difficult for Redcaps to figure it out. So the price in vis might be excessively high and it might also be in preferred Arts, either or both. Such a transaction is going to be a combination of things, and the reason I haven't opined on it, is because it's going to rely upon some bargaining with a Redcap to do the deed. The journey to acquire these texts will be long and arduous. What do you have for him?
