The Helm of Awe (Old NorseÆgishjálmr) is one of the most mysterious and powerful symbols in Norse mythology. Just looking at its form, without any prior knowledge of what that form symbolizes, is enough to inspire awe and fear: eight arms that look like spiked tridents radiate out from a central point, as if defending that central point by going on the offensive against any and all hostile forces that surround it.
