The Logbook (Arcane Quest 1-4)

Synopsis
In the cockpit I found an old logbook signed by my father. There were notes on the volcano study. I learned from them that the expedition had run out of fuel and they couldn't use the plane anymore.

Completion
Now I know that I am very close to my objective. My father's expedition is somewhere nearby. When I came back to Indim, I told the savages the red dragon ordered them to guard his nest. Now these Inuit won't be able to carry out raids on the valley.
