ástkách

Could you clarify what "ástkách" refers to? It isn’t a clearly identifiable term in widely used languages, so I want to ensure I write an accurate, neutral wiki-style article. Please provide:

- the language or context (Czech, Icelandic, a place name, a cultural term, a fictional concept, etc.)

- a brief definition or scope (is it a concept, a group, a location, a work, or something else?)

If you’d like, I can also draft a neutral stub for a fictional term or a placeholder entry and fill in details once you specify the context.
