In regards to mapping, this was another key component of being a good adventurer. One must always know where one is going and where one had been. Although the world is teeming with kingdoms, empires, and billions of people, the majority of this world is uninhabited. The glacial mountain range alone spans tens of thousands of kilometres and is home to a near constant snow storm, finding one's way is a dire necessity. Frost only managed to get to his intended destination for a few reasons, his highly detailed map that was given to him by Leo. The rather easy location of his destination – only going to the Gamma sector- and from asking Callie about the route there.
The deeper one enters into the glacial mountains the more expansive it becomes, and the maps become less and less detailed. For someone who is not a native or a skilled explorer they could wander for weeks without finding proper shelter.
