If any of you are familiar with Nausicaa of the valley of the wind, you probably remember the airships. If you never heard of it, it's a Animated film and manga series by Hayao Miyazaki. Anyway as a play i am constantly reminded of the wooden Airship (Dorok Monitors) that the Dorok empire uses.
Or the Toromekian airships and corvets.
BTW will we get serpents to use for our heraldry?
Yes! Ghibli films in general are a big inspiration for the game. Howl's Moving Castle in particular. And Miyazaki is clearly pretty obsessed with flight and flying machines.
