Magister Clayton:
Oh, this is... I do not know your purpose, but it looks as though you are seeking a new type of spell medium...
And a very powerful one at that...
It will be difficult, but I believe I can create it according to these specifications.
Unfortunately, I am missing a key ingredient.
Apparently, in order to create it, I will require 5 Glass Jaguar Crystals.
Interesting... You see, I am also keenly interested in new magic.
I will make you a deal. If you bring back 5 Glass Jaguar Crystals, I will create an empty Book of Seal set for you at no cost.
In case you were unaware of it, Glass Jaguar is a malignant spirit in the shape of a leopard that guards Plains of Dion.
