pomrná

Could you clarify what "pomrný" refers to? For example, is it a word in a specific language (likely Czech or another Slavic language), a place or surname, a cultural or historical concept, or perhaps a fictional term? Also, should the article be based on real-world usage with verifiable sources, or are you looking for a concise, fictional encyclopedia-style entry? Once I know the intended context, I can write a neutral, under-300-word wiki-style article accordingly.
