The Helm of Awe (Old Norse Egishjalmr) is a type of rune stave - a magical spell of protection used by early Vikings. It is one of the most mysterious and powerful symbols in Norse mythology. Its eight arms look like spiked tridents and radiate out from a central point, defending that point against any hostile forces that may threaten it. It was intended to be a magical symbol of overpowering might which, like the mythical Norse dragon Fafnir, could paralyze its prey before even striking, The "arms" of the Helm appear to be the Z-rune, often called "Algiz" or
"Elhaz" - the rune of protection and prevailing over one's enemies. According to legend, this protective symbol, when worn between the eyes, conferred invincibility on the wearer and instilled fear in one's enemies. Today, it is used as a charm of protection and as a symbol of identification by believers of the Old Norse "Ásatrú" faith.
