The Mask (Kingofevil9)

Information
The Mask is an ancient artifact from Japan created by Shadow Sorcerers during the first Shadow War. Designed after ancient Japanese ritual masks, The Mask was designed to be an all powerful cure to any disease that the wearer possessed. However, the downside was that any being that was not of Shadow descent would be driven insane as the Mask turned the victim into it's host, fusing to their face and possessing their minds. It was later locked away in a temple as a way to keep it's power out of enemy hands, however that all changed the day Hector Shinzuri and his friend Rin entered the temple centuries later...

Trivia

 * The Mask is based off of Majora's Mask from The Legend of Zelda
