Create an enchanting and adventurous book cover for "Kieran and the Crimson Amulet." The scene should feature Kieran, the young hero with both elf and demon traits, standing in a mystical forest with ancient trees that glow softly in the dark. Kieran should be holding a glowing amulet that emits both light and shadow. His companions—a fierce elf archer, a gentle ogre, and a half-dryad with nature powers—should be standing by his side, ready for the journey. In the distance, show the entrance to a dark, mysterious cave, hinting at the dangers ahead. The title "Kieran and the Crimson Amulet" should be displayed in a magical, ancient-style font at the top, with the subtitle "An Epic Fantasy Adventure" underneath. The author’s name should be placed at the bottom in a classic, elegant font. The overall atmosphere should be a mix of magic, adventure, and mystery, drawing readers into the story.
