Dark knight on warhorse through fiery chasm - AI Image Prompt

A digital painting of a dark knight riding a warhorse through a fiery chasm under a stormy sky with lightning. 

Subject: A faceless armored rider mounted on a large, muscular horse galloping forward. The knight wears heavy metallic plate armor and holds the reins firmly; their eyes are obscured by shadows or helmet visor giving an intense expression. 

Clothing: Dark steel full-body armor covering both rider and steed with spiked shoulder pads, detailed gauntlets, and flowing dark fabric cape trailing behind them in motion. 

Action: The horse is captured mid-gallop with front hooves lifted high off the ground; its mane flutters dynamically while sparks fly around it as if moving through embers or magical fire particles. 

Environment: Jagged rocky terrain beneath their hooves surrounded by glowing orange flames and floating embers rising upward into a cosmic twilight sky filled with stars, distant lightning bolts, and nebula-like clouds of blue light contrasting against fiery reds below. 

Camera: Mid-range shot capturing full body composition from slightly low angle to emphasize power and scale; depth of field keeps focus sharp on foreground subjects while background blurs softly for atmospheric effect. 

Lighting: Dramatic dual-light scheme   cool celestial glow illuminating upper portion including sky, lightning arcs, rider's face area, and parts of armor reflecting starlight; warm fiery illumination from ground level casting dynamic shadows and highlighting edges where fire meets metal surfaces creating dramatic contrast between cold above and hot below. 

Style Details: Fantasy art style blending realistic textures with stylized lighting effects reminiscent of AAA video game cinematics or concept artwork for epic quests; high detail in metallic reflections, flowing motion lines, particle effects (sparks/stars), and volumetric fog enhancing depth and moodiness overall tone feels cinematic yet mythical combining elements resembling Lord of Rings meets Dragon Age aesthetic.
