Dark fantasy book cover featuring a silhouetted figure with a sword, demonic red eyes, and geometric shapes.

Dark fantasy book cover. A lone figure seen from behind, standing still, a slender sword held loosely at his side. The figure is a pure black silhouette, no detail, no texture. The background is dark but not pure black — deep charcoal, with subtle gradients suggesting depth and atmosphere. Above the figure, a large Penrose triangle drawn in thin, precise, geometric lines — impossible, slightly luminous in pale grey-white. Inside the triangle, two enormous eyes, deeply demonic and terrifying — not human, not animal, something older and wronger. Glowing red with dark violet undertones and subtle deep purple reflections, like light bleeding through ancient evil. Pupils vertical and fractured, irises cracked like burning embers, surrounded by darkness. Staring directly outward with absolute cold malevolence. In the lower right area, a small Y symbol made of seven distinct dots — visible but small, intentional, slightly luminous, positioned low enough that the subtitle text partially overlaps it, as if the text sits in front of it, the Y bleeding through from behind. Minimalist composition with generous empty space. Japanese ink influence. Cold palette — blacks, dark greys, pale whites, the red-violet eyes as the only color, striking and deeply unsettling. Cinematic, melancholic, timeless. Title typography: elegant, sharp, slightly condensed serif font with fine strokes — reminiscent of high-end literary fiction, not generic fantasy. Title reads: "L'ombre et son voyageur". Below Ver más
