köldr

Could you provide some context for "köldr"? Is it a real term from a specific language or field, a place, a person, or a fictional concept? If you can share what domain it belongs to (science, geography, culture, technology, etc.) or a rough definition, I can generate a concise, neutral wiki-style article (under 300 words) tailored to that interpretation. If you’d like, I can also create a fictional encyclopedia entry for a term named "köldr."
