A pair of adventurers recently found a queer stone in the mountains to the far north. They were returning late from the assaults on Frore, and became lost in a late blizzard. They took shelter in a small ice hut near 90 degrees north latitude. It was defended by golem and wisps. Once these were slain, they discovered a strange blue stone and a book within the hut. These seem to be artifacts of some lost form of Empyrean technology.
