After leaving the mouth of the cave and heading to towards the river off in the distance you came across an abandoned village. The village looked like in would have been built in a warmer climate, but it was covered in snow. In the village you found the bodies of three of the villagers, on of the carried a journal documenting the slow demise of the village.
You left the village and traveled north along the river until you found a town inhabited by humans and frostfolk. The village was controlled by the Frost Queens minions, and in the temple was a frost crystal. After killing the Frosts Queens minions the crystal in the temple shatered and the people of the town who had runes placed on them started screaming in agony.
