Precious Cargo

Q: Where is the navigation orb?
A: In the hut next to the lighthouse, there is a secret room on the second floor with the navigation orb inside. You open it in the attic with a switch located near a crack in the floor.

Q: Where can I find the key to storage room #5?
A: The key to storage room #5 is in the sub-aquatic station #1. This station has a room with a lever that opens the entrance to this station. Look there for a hole in the floor where you can access the basement. In the basement, you will encounter several rooms where the water is a few feet high; in the last room, the key lies on the floor. (under water!) The key is of orange-golden colour, so you can't miss it.
