"Fantasy book cover illustration in vertical format. Foreground features four main characters: a fierce red-haired barbarian in leather and fur, holding a battle axe, a blond strong and tall paladin in shining armor with great-sword ready, a druidess with voluminous and ginger hair and green dress, and a pale young curly haired necromancer holding a glowing skull. In the background, a massive stylized black skull looms in the sky, with swirling red smoke and magical energy. The setting is a dark, desolate battlefield with mystical tension. Leave space at the top for the book title and at the bottom for the author's name. Dramatic, detailed art style, with strong lighting and dark fantasy atmosphere."
