XIIan

XIIan is a fictional term used in science fiction and fantasy narratives to denote a group, most often a species or political entity, that appears across multiple independent works. There is no single canonical XIIan; the concept and details, including appearance, culture, and history, vary by author and medium. The name is typically derived from the Roman numeral XII, and in some uses it signals numerology, lineage, or a twelve-part organizational structure.

Depictions of XIIans are diverse. Some writers describe XIIans as humanoid, highly advanced, and spacefaring; others present them as alien or nonhumanoid, with cultures that range from technocratic states to ritual-based societies. Because the term is not tied to one official canon, XIIans are often used as a flexible world-building device to suggest otherness without prescribing a single profile.

In practice, XIIan material appears in a variety of formats, including novels, video games, tabletop role-playing games, and fan works. The lack of a fixed canon means that each portrayal tends to reflect the concerns and stylistic choices of its creator, rather than a universally agreed-upon XIIan blueprint.
