There's not much to describe, as most of this 30' by 30' room is taken up with a large hay pile, a heavy wooden table and two chairs of minotaur size, and a low shallow hole, ten feet wide, filled with sand that appears to have been used as a toilet. There are dried pats that have been rolled in the sand. The position of the hole correlates with the image on the map that says, 'floor.'
There are four massive books, minotaur sized, each of which would weigh about 45 lbs. with a font size of approximately 18. Each book is 30 inches by 19, bound with wood and twine, and tied shut both along the spine and along the front, so they don't open without untying. Each is about 3 inches high. One is "History of Circassia"; another is, "Father Axus"; a third reads, "Enkidu and the Minotaur"; and the last is written in script that is unrecognizable.
No obvious treasure exists.
More I'll answer in the comments.
