dlostelstvo

Could you specify the language and context for "dlostelstvo"? It does not appear as a widely attested term in major languages, and I want to ensure I write a neutral, accurate wiki-style article. For example, is it a real term in a specific language (and which one), a historical concept, or a fictional/academic term? If you provide the context, I can draft a concise article (under 300 words) in plain text.
