The Helm of Awe symbolizes Invincibility, Strength, Protection and Power. It is one of the most powerful yet mysterious symbols in Norse mythology.
Eight arms that look like spiked tridents defend a central point against all forces that surround it - it is an overpowering symbol that was meant to strike fear upon enemies.
"The Helm of Awe
I wore before the sons of men
In defense of my treasure;
Amongst all, I alone was strong,
I thought to myself,
For I found no power a match for my own."
- The Poetic Edda. Fáfnismál, stanza 16.
