A group of business people were trying to salvage some mining equipment 2 hexes outside of your patrolled border. They had set up a temporary camp, and were creating a list of all the goods present. Then thery were attacked by frost giants who carried the supplies away. There was a smaller hideout half a days march into the mountains. From here Rodryq and Romulus were able to track them 2 1/2 days to their larger cave. Here they found a scroll containing an itemized list of mining equipment. They also found a scroll in a language that you do not know. It seems familiar, perhaps from your interactions w/ the Yuan-Ti.
Leading the frost giant was a cloud giant with 2 ice elementals.
