* Superior Griffin armor, silver sword, and steel sword diagrams
== Journal entry ==
:Beautiful. Professor Slavko Atimstein will be furious. I lost the first map in a game of gwent, and then the second was stolen from me while I was slightly indisposed after a hard night in the casino. I cannot arrive empty-handed at the station near the tomb under Crookback Hills or the professor will vivisect me on the spot. The four new locations I have marked on this map might be enough to protect me from his wrath.
:Edwin Greloff. Adjunct in Natural History at Oxenfurt Academy
