Köln

Could you clarify what you mean by küln? It is not a widely recognized term, so I want to ensure I provide the right article. Here are two common possibilities:

- If you meant Köln (Cologne), the city in Germany, I can provide a concise, neutral wiki-style article about its geography, history, economy, culture, and notable features.

- If küln is a fictional term or refers to a specific concept, place, or organization you have in mind, I can create a concise, neutral wiki-style article for that subject.

Please tell me which one you want, or provide a brief description of what küln refers to, and I’ll write the article (under 300 words).
