lúggal

Could you clarify what lúggal refers to? Is it a real term in a specific language or field (for example a place, a person, a cultural practice, or a linguistic concept), or would you like a fictional or hypothetical concept presented as a wiki-style entry? If you have a context (such as linguistics, anthropology, geography, literature), please share it so I can craft a concise, neutral article under 300 words.
