I've managed to salvage some of the text out of my blurry, underexposed jpegs of the next page of the book. Borlase doesn't give anything useful about the location, but he has a page long waffle about how in one Circle, the Boss Druid would be doing his thing, whilst in another, a sub Druid would be cleaning the Boss Druid's sickle, whilst in the outlying one's novitiate druids could have been busy learning how to read chicken guts etc. etc. All pure conjecture of course, but he seemed quite taken with the place, so I think I am actually inclined to believe that he'd seen something he thought was the real deal.
