The Book of Destiny is an ancient tome with the Mortal Kombat dragon symbol imprinted on it that contains the entire chronicled history of the Mortal Kombat tournament, as well as detailed stories of many past warriors from all other realms. It first appeared in the beginning of Mortal Kombat Mythologies: Sub Zero.
This ancient tome contained vast untold secrets. The book also chronicled the chaotic battle between the Elder Gods alongside the Earthrealm's thunder god Raiden, and their treacherous brother Shinnok, who sought to overthrow his fellow deities and rule all of creation.
This antique was last seen in the possession of the Thunder God Raiden.
