Mezza's Plate Armor of the Hells

"It's not so much that I'm a fallen Paladin, so much as that I jumped down here." - Mezza, the Fallen

Mezza was never a shining example of a Paladin. He was always one to get his hands dirty if the task called for it. This led to his eventual twisting by a devil. He was manipulated into killing innocence.
When given an opportunity for redemption he instead decided to pursue the devil who twisted him into the nine hells.
He fashioned Mezza's Plate Armor of the Hells from the fiendish skulls he took along the way to his vengeance. No one knows where either he or the armor are to this day.
