Create an illustration in the style of a fantasy book cover. Background: A mystical landscape that combines diverse elements representing each character's cultural background—a blend of vibrant colors and dark, shadowy areas to give it an ethereal feel. Character: An African male, his facial features shrouded in dark energy. He should have an imposing stance, with red and blue separately lightning crackling throughout the scene, illustrating his mastery of lightning and armageddon magic. The character is 18 years old. He is holding a longsword in each hand. There is a large moon in the background behind him.
