Why are there so many npcs who know little about their basic trades? All in good time I am certain.
Why is it that Jayose know little about the books in his library, he ought to be able to answer some questions about their content, even if his memory is not encyclopedic, and the same question for Kerryk Cor and his archives. If it is just that so much to do and it is planned, fair enough, otherwise allow me to suggest it.
Still, you would expect a self-proclaimed archivist to know what an archive is and at least be able to mention the names of the materials involved in his quests when asked about his archive or his collection. Are there any plans to make those materials readable? At the moment they are pretty generic quest items with a brief description.
Keep up the good work!
