muromaanse

I’m not aware of a widely recognized concept named "muromaanse." Could you specify what you want it to refer to? For example:

- a demonym or cultural group related to Muroma or Murom in Russia

- a language, dialect, or linguistic term

- a historical or cultural movement

- a fictional culture or term from literature or media

If you provide the intended context, I can draft a concise, neutral, wiki-style article under 300 words.
