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: A male Norse tank stands solidly with a warrior's heavy armour adorned with icy motifs. His stance is protective, with sharp ice and metal magic and deep green poison fractals swirling in the air around him. His face is visible but he wears head armour. He is exactly 18 years old and looks young.
