katastrid

Could you clarify the intended meaning of "katastrid"? It does not correspond to a widely recognized term in English-language reference sources. Do you want:

- a real-world encyclopedia entry for a term that exists in a specific field or language (if you can specify the field or language);

- a fictional or hypothetical entry for a term you invent (for example, a creature, place, or organization in a story);

- or something else?

If you’d like, I can draft a concise, neutral stub under 300 words describing a fictional or generic concept of "katastrid" with a neutral tone.
