Nightmares Awoken

Nightmares Awoken is the second black book to be found. The box probably materialized itself into existence on the Death Star. The book, when approached, caused the Nightmares to enter the realm of Apocrypha.

Trivia

 * This Black Book functions just like the Black Books from Elder Scrolls, as it's supposed to be one of them, though applied to Nightmares. If this is the case, however, just having the book should give the reader skills. Then again, they can only be read in Solstheim, and the Death Star was nowhere near it, so this might be why nobody got any skills.
