Bheur

Bheurs, also known as winter hags, are found commonly in Auril's realm within the Deep Wilds as well as within the mortal nation of Rashemen on the Prime Material Plane. They live for the pleasure of bringing icy doom to as many people as they can. A common legend in Rashemen and surrounding lands suggests that there is only one bheur alive, because no more than one has been seen at a time, but it is far more likely that they are solitary wanderers. This is, in fact, false and bheur hags are the most common of Auril's handmaidens.

Every winter, just before Tarsakh, hathrans are sent to battle the bheurs. If the hathrans fail in their battle, then spring is delayed for several more weeks in Rashemen.

Bheurs are vulnerable to lightning/electricity.

Description
Bheurs resemble hideous old women, like all hags do; however, a bheur's skin is blue-white, with white hair.
