Mask

The Mask is an item found in Red Dead Redemption. It appears to be the cause of the Undead Plague in Undead Nightmare, after it was removed from the catacombs beneath Escalera by Abraham Reyes. After it is returned by John Marston, the world reverts back to its original state. However, it is stolen by Seth Briars a few months later, leading to a new undead outbreak.

Characteristics
The mask itself is made of stone, green in color, and appears to be of Aztec design. (probably Jade)
