After that night, Ashley issued an order throughout the Grand Duchy stating that hunting or killing Winter wolves is prohibited and punishable by getting frozen to death or banished. The people initially opposed it, but Ashley told them that this fight between the wolves and the humans only started because humans started it by killing one of them. She even made the people learn about the wolf's cautiousness towards the humans long before the fight began.
Also, the weather in the North had been going well since the fight. The snowstorms don't come often that much like before. Her request to Melek to talk with the Deity of Seasons seemed successful. Although the snow was still piling up, and they still faced the cold, merchants could travel in the North now.
