Into the Darkness is a "cede the castle" mission where you'll have an opportunity to defeat the Wolf and the Rat all in one game. As the mission name suggests, tunelers may be helpful to you. You are asked to take on the task to free a stockade of peasants and secure a castle for the Crown. There are good degrees of stores to be gathered in addition to fending off a fierce counter attack if you succeed at capturing the castle. Good luck.
