. She is frustrated with continuous visits from people asking about local matters such as the Iron Crisis and rampant banditry, while she is occupied with greater concerns in the wider world. She can be killed without penalty.
I know why you're here. It's the same reason everyone else comes to see me, and you shall get the same answer. I do NOT know when the iron shortage will let up, I have NO CLUE as to who controls the bandits in the area, and I have NO INTEREST in accompanying you to the gambling tables in Baldur's Gate.

If you are polite, you may be able to glean a modicum of information from Pallonia. Her predictions are indeed true, as she will hint at "troubles brewing in great Amn" (a reference to Irenicus' scheming and the whole plot to unfold in Baldur's Gate 2), and another event to the far North, in "a city where winter never rears its ugly head" (a reference to the plot in Neverwinter Nights). However, no matter your answers, she will leave after the conversation.

Well, just across the southern mountains there are troubles brewing in great Amn that will make our current concerns seem small by comparison. To the far north there is a city where winter never rears its ugly head: a city that has not been seen nor heard from for many a year, but will soon welcome the return of a multitude of citizens. Both of these events will unfold regardless of our current troubles. Great may be our concerns, but much more is on the horizon. Leave me be, I have much to think upon.
