Strange tileset details

Strange table in a tent...

In interior tileset, there's also a nice interior of a tent to put wilderness folks into. This table, however, is quite odd.

Map of...?

NWN is set on Toril, yet there's a fairly detailed map of Earth on the table?

Philosophy textbook

The book, obviously published by Bioware, is written in Greek and obviously deals with classical philosophy, as can be seen from the title of the book: "This is a book". (I hope some other tent has a book on modern philosophy, in French, that is titled "This is not a book". =)

Table on the table

Here's the text on the table, flipped horizontally so it's readable. No comment.
