If I go on a trip, I'll bring my laptop and make the comic abroad. As for the reaction of the guy...

If never really supported the idea of nameless, characterless NPCs. They are easy to create on the go in things in which they are more practical (i.e. Video Games, Tabletop games, etc.) but not when it would be easy to just make a one-time character. I hoped to convey that young helmeted man's experiences in one shot, just as I tried to display the relationship between those two dwarves.

(P.S. If anyone can name the profession of those dwarves, they get a cameo. Yes, it is really hard.
