perehtyi

I’m ready to write a concise wiki-style article, but I need to know what Perehtyi refers to. There is no widely recognized subject by that exact spelling in major reference sources, so the context will shape the entry. Could you specify:

- Is Perehtyi a place (geographic feature or locality), a person or surname, a linguistic term, or a fictional/conceptual entry?

- If it’s tied to a language or region, which one should guide the etymology and usage?

If you’d like, I can also draft a neutral stub as a generic disambiguation entry or as a fictional concept until you provide real-world details.
