Thor's Helmet is a majestic piece of armor designed with photorealistic detail, featuring a robust, rounded dome with intricate Norse engravings depicting thunder and lightning motifs. The helmet is crafted from aged, darkened metal with a slightly weathered finish, showcasing battle scars and a matte, non-reflective surface to avoid glare. It includes a pair of curved, horn-like protrusions at the sides, symbolizing Thor's divine power, and a chainmail aventail attached to the back for added protection, all while maintaining historical authenticity with a fantasy twist.
