White Madness

A couple of hours ago an Orc is smoking clothes fell out of the tower Portal. Judging by her armor, she is one of Demon Hunters. But Demons have been keeping away from our allods since the battle of Yazes, and then we crushed the in the Dead City! This is very strange.
I am afraid our guest is a little bit out of her wits. She doesn't recognize anyone and doesn't answer any questions. The healers can't even approach her.
I remember that you once met Demon Hunters in the Dragon Ring. Why don't you try to talk to her?

Talk to our guest. She's from the Fiery clan. Maybe, she will recognize you at least.

White Fortress? Yes, I think I heard something... It's on Dane, the allod of Free Traders. But what on earth is "flowing stone"? What could have possibly happened? Could it be demons?!
Damn it! That orc had some papers, but they are all tattered and covered with blood. Looks like we have only one way to find out what happened...
