reikinio
Could you clarify what "reikinio" refers to? It isn’t clear from the term alone whether you mean a place, a person, a concept in a specific field, or something else. If you can provide context, a region, language, or a source, I can write a concise, neutral wiki-style article (under 300 words). If you’d like, I can also draft a disambiguation-style stub that outlines several possible meanings and invites further specification.
