However, nautical charts can be further divided: general nautical charts, offshore nautical charts, coastal nautical charts, coastline charts, bay charts, and so on.
Each type of nautical chart serves a different purpose, and their values vary. For instance, the one Adrian has is merely an offshore nautical chart, with a very limited scope, only covering the patrol route of the "Conch" and some nearby coastal cities.
Despite this, Adrian treasures it as if it were a prized possession, as this is essential for a Chief Navigator's livelihood.
To be honest, from the nautical map's perspective, the fishing town Leopold and the Third Fleet's base Gabred are not very far apart. Back when Aiven left there to join the military, traveling by the "Yellow Crane" took only two days in total.
