The Knights of Chemois, who fled the Duke's Tower after they were sent away by Sir Phillip, faced hell as they traveled. Not only was the weather freezing, especially in the central mountain range that they would have to travel over to get to Hydrogia, but they also had minimal supplies since they left in a rush.
Since going into the Duke's Tower for supplies was out of the question, they could only go to their barracks and find what was minimally required to travel. Warm clothes, what food they had from other trips, and the weapons already on their person.
The lack of preparation led to slow travel because they had to hunt most of what they ate. They had to cut down trees or hope one was already down if they wanted firewood. They relied on the lands and everything they learned prior was absolutely vital to their journey.
