During the Third Northern War, the forge was forced to supply armor to Nilfgaardian forces who had conquered the region.
One night in 1272, a drunk local set fire to the workshop, burning it to the ground. Willis lost most of his equipment, managing only to salvage an anvil, and some basic tools. He sought assistance with the local Nilfgaardian command, for whom the arson was a major strategic blow. Supplies were ordered to rebuild the workshop. Meanwhile, Willis also asked Geralt of Rivia for help in tracking down the arsonist. The forge was eventually rebuilt.
