I have found a place under the Warrior's Guild... In the 2nd level of the chamber you enter (first encountering Insane Conjurers), in the Westernmost room with a lever, there is a hole in the ground that does not highlight when you mouse-hover over it.

I clicked on it, and my character ended up in THIS ROOM.

In there, is nothing up a manuscript (I forget the name), that when clicked on shows this:

I must know what this place is.. before I abandon it.

More or less because, once I climb out of there, I can't get back in... No matter how many times I click on the same area.. My character just doesn't want to climb back down..
