Herzhi'n tend to be extremely knowledgeable about all kind of secret, occult and arcane lore. However, even them are unlikely to know all of the following articles. Consider that a Herzhi might know the main idea of these articles but like the finest details of the most specific ones. Master, on the other hand, will have an encyclopaedical knowledge of these subjects.
Some extremely well versed scholars might have some insights about few articles, but, except if given access to these information by Herzhi'n themselves, most of the topics will be even unheard of.
