I see the mask of an ancient warrior that portrays the stern and stoic face of his god. He wore the mask in his final battle and was buried with honor, this mask over his face.
Through eons of time, soil, water, and the mineral content of his burial tomb turned select metals of the mask a bold blue which further enhanced the craftsmanship of the mask.
Natives who uncovered the warrior's grave say it is the essence of the god resting with his soul.
