" We worked for the four days of that blizzard, loosening the mortar in the lower stones of Castle Munth. The wind and storm did the rest; after the walls fell, we melted snow from uphill with our combined Fire Sticks. The resulting flood was impressive.
By the next morning, when the scouts we left behind saw the first of Debegri’s soldiers march up the road, the whole mess had frozen into ice, with our ex-prisoners wandering around poking dismally at the ruins. It would take a great deal of effort to make any use of Munth, and the scouts were still laughing when they came to report. "
