andisão

I’m ready to write a concise wiki-style article, but I can’t locate a widely recognized definition for "andisão." Could you clarify what andisão refers to? For example, is it a term from a particular language, a place, a person, a cultural practice, or a fictional concept? If you’d like, I can draft a neutral stub in either a factual context (based on real-world sources you provide) or as a clearly fictional concept. Please specify which you prefer, and I’ll produce a concise, under-300-word entry.
