Vangkolk

I can help with a wiki-style article, but I need a bit more context for "vangkolk." It does not correspond to a widely known real-world topic, so it could be a place, a person, an organization, or a fictional concept. Could you please specify:

- What does vangkolk refer to (a real place, a surname, a company, a term in a work of fiction, or something else)?

- If real, what country or region is it associated with?

- If fictional, which book, game, or world does it belong to?

If you’d like, I can also create a concise, fictional wiki entry for a place named Vangkolk, including etymology, geography, history, and culture, kept under 300 words.
