Hey! What Ever Happened To *This Place* In Book II?!!

[IJBall]

OK, so my question about Fathamurk has already been asked, and answered.
But now I've got a new question!

So, what the heck ever happened to this place?!

Or is it, by chance, in Barrea?!
In which case we might see it in Book III!!...
