I haven’t encountered ANY dwarves with Russian flavoring.I know "Scottish Dwarves" is like, a huge thing in the fantasy genre in general, but my Dwarves have always been more of a mix of German and Russian. German for having a ton of compound words in their language, and Russian for the harsh consonants and lots of o's and u's in their language.
If I did today, I’d probably chuckle a bit given how tall they seemed on average when I visited Moscow and St. Petersburg 15+ years ago. I’m 5’7”, but noticed certain architectural ergonomics there made me feel positively short(er).
