I'd be surprised if the Palace of the Collared Coin didn't end up becoming a dungeon later in the patch cycle, especially after the Dotharl mentioned there's some manner of crystal hidden within its depths that they believe to be a fragment of Nhaama.

It would probably be creepy as all heck, considering that it's also where they go to escape their cycle of reincarnation by reuniting with Nhaama (That is, they commit suicide by hurling themselves into the depths of the palace).
