Armorer of the Underworld, clad in ancient battle gear, astride a monstrous steed from the abyss, horrific and awe-inspiring, surrounded by an intricate tapestry of shadows and intricate runic designs, capturing the essence of photography lighting with ethereal light rays cutting through the darkness, photorealistic and cinematic in scope, enveloped in a textured cinematic grain, rendered with the pristine clarity of octane rendering, sharp and focused detail in 8k resolution, hyperrealistic with advanced VFX post-production elements, illuminated by RTX ray tracing lighting, an art piece worthy of ArtStation and CGSociety, all unfolding in a 9:16 frame of haunting majesty.
