Luminant Archivist on Alien Twilight Ridge

Vertical 9:16 full-body cinematic portrait of a single alien character, the Luminant Archivist, standing on a rocky ridge on the twilight band of an alien planet; the creature has a tall elongated body with three root-like legs forming a stable tripod, lower torso textured like smooth bark and sinew fused together; two long arms with four segmented joints each end in multifingered, tendril-like manipulators gently holding a glowing hexagonal plate; instead of a human head, the upper torso flares into a tall crown of layered translucent plates arranged like a vertical fan, each plate lit from within by faint cyan neural patterns, no face, no eyes, no mouth; along its back and shoulders grow rigid bioluminescent data plates, flat hexagonal organisms clinging like barnacles, softly pulsing in cyan, teal and occasional warm amber; the body is draped in a partial organic mantle made of fibrous membrane and chitin filaments, not clothing but grown; background shows a perpetual dusk sky with a low orange band on one horizon and deep indigo on the opposite, distant silhouettes of hollow spires and tiny other Archivists crossing the landscape; ground covered in reflective glassy lichen and small crystals catching the character's glow; palette of deep indigo, dusty violet, cyan glows and subtle warm amber accents; strong horizon rim light outlining the Archivist's silhouette, subtle backlighting from the bioluminescent plates, gentle atmospheric haze; realistic but slightly painterly rendering, extremely detailed textures on skin, plates and lichen; composed like a high-end sci-fi character poster, vertical 9:16 aspect ratio, full body in frame, centered but with enough headroom and ground visible to feel part of a larger universe.
