Sammael is at Graendal's hideout in this chapter and makes some interesting observations...

LoC

It never ceased to amaze him that she chose to remain here in a palace well known across Arad Doman, with civil war and anarchy all around her.

So according to him her palace is well known across AD... compare that to Rand's comments.

Among the general Domani populace, Natrin's Barrow has been largely forgotten.

Something of a disconnect. Then there is this other interesting observation Sammael makes about Graendal

LoC

She liked her comforts, and never wanted to expend much effort to keep them, yet this palace was in sight of the Mountains of Mist, and considerable work was necessary to keep the turmoil away from her, to keep anyone from asking where the former owner had gone, along with his family and servants. Sammael would not be surprised if every Domani who visited here left believing that this land had been handed down in her family since the Breaking.

Funny that it took Rand no time at all to discover something odd about Natrin's Barrow...

The King fell, but his successors also used the fortress, and it became a popular retreat for the Crown when the King needed relaxation. The practice dwindled during the last hundred years or so, until it was granted to a distant cousin of the King about fifty years back. Their family has used it ever since.

And then there is this final tidbit about Graendal that Sammael gives us...

LoC

She used Compulsion so often like a hammer that one might forget that she could wield the weaker forms of it with great delicacy, twisting a mind’s path so subtly that even the closest examination might miss every trace of her.

Yet her Compulsion of Ramshalan (and Kerb's earlier for that matter) stood out quite obviously...

TGS

Nynaeve walked over to Ramshalan and looked at him for a moment. She hissed and said, "Yes. Rand, he's under a heavy Compulsion. There are a lot of weaves here. Not as bad as the chandler's apprentice, or maybe just more subtle."

Big discrepancies IMO between information we had been given earlier and what now seems to have taken place in TGS. I'm beginning to wonder if Rand even BF'd the right place!
