Bi'an

The provided sources identify Bi'an as one of the Nine Sons of the Dragon, a traditional enumerated group of dragon‑offspring in Chinese mythic catalogs. In that capacity Bi'an appears as an entry in classical-style compilations and pantheon lists rather than within a single coherent origin narrative: the Archive.org catalogue lists Bì'àn among many named divine personages and dragon-sons, and Wikidata labels Bi'an explicitly as "one of the 9 sons of the dragon." The supplied materials do not give a narrative account of Bi'an's birth, parentage beyond membership among the dragon sons, or an independent founding myth.

No independent, source-attested physical description of Bi'an is provided in the supplied materials. Bi'an is named in catalogues of mythic beings but the sources do not supply characteristic features, iconography, or consistent depiction tied specifically to this name. The only concrete visual description in the provided set refers to the separate Heibai Wuchang pair ("dressed in black and white respectively"), but the sources do not equate Bi'an with those figures and therefore that description is not ascribable to Bi'an on the evidence given.

The sources do not record explicit powers, behaviors, or functions unique to Bi'an. The only direct attestation is classificatory: Bi'an is listed as one of the Nine Sons of the Dragon in both a cataloguing volume and a linked Wikidata entry. Separately, the Heibai Wuchang article describes death-escort duties for that named pair; while this indicates the presence in Chinese folk religion of specialized death-related functionaries, the provided sources do not attribute those abilities or roles to Bi'an himself.
