From the Cold Dark Sky (SUNDAY) 8

The party begins their trek across the expansive ice plain, as they progress, they notice a strange crack in the ice, which they investigate, and find a gem-like object deep into the crack. After they retrieve it, they place it on top of the strange cube like device, and it activates, tracking the storm that approaches the party from the mountains. After traveling for the day, the party sets up camp with a magic hut, which Vilmi booby-traps. During the watches, the party notices strange things in the storm, during the final watch, Vilmi's traps are triggered due to something, and there is some scuffle that goes on. Morning rolls around, the storm still rages outside, and none is sure what happened during the night.
