Karhila

Passenger of the first class nooner.
He is aboard the Magic Arrow as a subordinate of Luukkanen and an Imperial Intelligence Officer. An informant is expected to behave in a manner not unlike an informant. Calhill has these qualities, and has no particular characteristics or shortcomings. However, no matter when or where you meet him, you will always remember him. He has that kind of airy atmosphere.
The first thing that comes to mind is the fact that the man is a very good friend of yours. Even the most horrifying words, when spoken by Calhill, sound as natural as water seeping into the earth.
Webley-Fosbury carries an automatic revolver. Unlike Luukkanen, he can use both arms when shooting, so he wears a bayonet and a stock that doubles as a holster to increase his accuracy.
As an intelligence officer, he is not only knowledgeable about military matters, but also about the stars in the night sky.
