A hyper-realistic book cover for a historical novel about the Albigensian Crusade. A medieval knight in authentic 13th-century armor, with a red cross on a white surcoat, standing on a rocky hill overlooking the fortified city of Carcassonne. The sky is dark and stormy, with dramatic lighting casting shadows on the stone walls. The landscape features dry Mediterranean vegetation (thyme, rosemary) and earthy tones (ochre, brown, dark green). The mood is epic, somber, and mysterious. Vertical composition (2:3 ratio), ultra-detailed textures (metal, stone, fabric), cinematic photography style, no illustration or cartoon elements. Mehr sehen
