Considered one the of the most mysterious symbols in Norse mythology, the Helm of Awe (Ægishjálmr) was intended to represent overwhelming strength, power and protection. With its 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.
It was even written that the havoc wrecking dragon Fafnir attributes much of his strength and invincibility to his use of the Helm of Awe.

Embrace the power of the Helm of Awe today!

"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.
