Oh hey, just noticed something.
A scorn-pole is a way of forcing curses upon those it is directed towards — curses and nid, depending on the reason. For such a thing to be erected not only on your father's lands but also pointed at your father's home, there would need to be a potent, heavy reason for it. A reason that simply doesn't exist.
There's Mental Fuckery afoot, because Halla knows one very good reason why someone might want to point a focus of Elemental Evil aimed at her father, and yet it never occurred to her that "This is another of Horra's tricks?"
That might be important later.
