Codex de figure mythologique

Compose a vertical encyclopedia poster profiling the mythological or legendary figure named in the user request, drawn in that figure's own visual tradition rather than generic fantasy style. Center a symmetrical full- or three-quarter-length hero illustration in a dignified stance, wearing the robes, crown, armor, weapon, or companion creature from the legend, against clouds, mountains, waves, or architecture of the same culture. Frame the page with period ornament: woven borders, ritual metalwork motifs, mural or scroll texture, mineral pigment on fibrous paper, gilded lines, and a small carved seal. Print a large title, smaller subtitle, and short elegant epigraph. Arrange lore modules down both margins as aged cards, tablets, or scroll strips — identity, origin, domain, appearance, relics and abilities, mount or emblem, famous tales, symbols, lineage, and cultural legacy — then close with a summary band. Choose a palette suited to the figure's element. Keep every label short and legible in the language of the user request, with no garbled or clipped text. No watermark or modern interface elements.
