The Path of Knowledge

Background
''In order to defeat Miraak, I need to find more of the Black Books, the source of his knowledge and power. Storn suggested that the wizard Neloth may know the location of the Black Books that I need.''

Consulting Neloth
At Storn Crag-Strider's suggestion, head to Tel Mithryn to ask Master Wizard Neloth about the Black Books. Arriving there, Neloth will remember you from the Earth Stone and agree to talk. When asked about the Black Books, he reveals they are artifacts of Hermaeus Mora, the Daedric Prince of fate and knowledge. He states that he is unaware of the origin of these books, but states their dangers. He admits owning one, and knows the location of another. Apparently, the Dwemer of Nchardak found one of these ominous tomes, and as per usual, took it for examination. It was left in Nchardak when it was abandoned. Neloth agrees to bring the Dragonborn to Nchardak so they can read the book. Nchardak is north of Tel Mithryn, along the coast and relatively close.

Trivia

 * Should the Dragonborn have completed the quest for the Oghma Infinium before beginning this quest, Hermaeus Mora will recognize the player as his Champion whilst saying the Oghma Infinium was "only the beginning". Only if this is the first book read after waking dreams. if you open black book winds of change second he will say it then and have no greating for you here
 * Neloth will comment on many things in the ruins. If a Follower is also along they will react to his with comments of their own, making for a very humorous effect.
