pirozeným

Could you clarify what “pirozeném” refers to? I can write a concise, neutral wiki-style article, but I need to know whether it is:

- a real place or entity (for example a town, organization, or landmark) with that name,

- a Czech linguistic term or grammatical form (for instance a locative form connected to a verb or adjective),

- a fictional concept or setting from a work of fiction,

- or something else entirely.

If you prefer, I can also draft a generic linguistic entry explaining possible interpretations of the word’s morphology and usage. Please specify the intended context and desired length (up to about 300 words).
