Create an image design featuring a futuristic warrior helmet instead of a knight's helmet. Change the helmet color to a gradient of silver and blue, with glowing green eyes. Replace the text "DEFENDER" with "GUARDIAN" in a bold, modern font at the top. Incorporate geometric shapes around the helmet and add a starry background instead of dots. Below the helmet, use a description that emphasizes strength and protection, avoiding specific brand references. Remove any logos or brand identifiers.
