Armored Bear Encounter

Create a dark epic fantasy cinematic illustration of {argument name="encounter title" default="Encounter with an Armored Bear"}: a colossal bear-like monster dominates the frame, lunging forward and roaring with its mouth wide open, fangs exposed, purple-glowing eyes, and enormous metal claws reaching toward the viewer. The bear is covered head to toe in layered blackened steel armor plates like overlapping scales, battered, scratched, riveted, and jagged, with heavy shoulder plates and a large ornate amulet on its chest holding a glowing {argument name="gem color" default="purple"} crystal. In the lower right foreground, show exactly 1 lone human knight seen from behind, much smaller than the beast, wearing dark ornate armor and a tattered cloak, holding exactly 1 long sword angled downward and exactly 1 large kite shield raised defensively. Set the scene in a ruined gothic city or fortress canyon with exactly 2 tall broken stone tower walls framing the left and right sides, storm clouds overhead, drifting ash, sparks, flying debris, shattered rocks, wet reflective ground, and eerie purple magical flames or energy erupting from the ground around the monster. Use a low-angle heroic composition, the bear filling most of the image, the knight providing scale, high contrast chiaroscuro lighting, cold gray-black metal tones with violet magical highlights, ultra-detailed textures, realistic fantasy concept art, dramatic volumetric smoke, sharp focus, vertical 4:5 aspect ratio, no text, no watermark.
