Create an ultra-wide cinematic dark fantasy medieval battlefield panorama in a grim, realistic style. The viewpoint is from a muddy hillside behind a dense army of armored soldiers, looking down across an enormous battlefield packed with countless infantry formations, spears, shields, banners, and cavalry. In the left foreground, place one huge torn crimson war banner on a tall pole, ragged and weather-beaten, plus exactly four smaller visible colored banners nearby: one blue-and-white striped banner, one green-and-white banner, one red patterned banner, and one pale blue-and-white cross banner. The foreground soldiers wear dented steel helmets, chainmail, plate armor, tabards, and round shields caked with mud; their backs face the viewer as they march or brace for battle. The middle ground should show massive ranks of troops stretching across the valley, smoke drifting low over the ground, scattered fires, churned mud, broken shields, and a chaotic charge forming on the right. In the far distance, include a fortified medieval city or castle on a hill, partially obscured by haze, with multiple smoke plumes rising behind it. The sky is filled with heavy storm clouds and a cold gray break of light near the horizon. Use a desaturated palette of iron gray, muddy brown, dark green, faded red, and smoky black. Make it look like a high-budget historical epic film still, with dramatic atmospheric perspective, harsh overcast lighting, detailed armor textures, cinematic depth, and gritty battlefield realism. No modern objects, no text, no clean fantasy gloss, no visible watermark.
