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 to one side, with a warrior's heavy armour adorned with icy motifs. His stance is protective, with sharp ice and metal magic and green poison fractals swirling in the air around him, showing his mastery of steel and ice. He is 18 years old.
