THE STORY: THE AVENGER'S MIGHT
Ignite the warrior within by paying homage to Mars, the God of War and protector of all Roman soldiers.

As a symbol of sovereignty and grit, Roman legions would invoke his name to find honor before the chaos of battle. Clad in grey and black, this "armour for the spirit" reflects the stoic power of a deity who soaked himself in the blood of his enemies.
