ソフロニア嬢、空賊の秘宝を探る

The mix of proper manners and espionage makes for such a unique setting. I'm curious whether this was planned from the start or evolved during writing.

The witty dialogue and quirky characters kept the tone fun, but I wondered if that balanced the darker spy moments well.

The details feel so immersive, from the technology to the social customs. Was there a particular historical era or idea that sparked this universe?
