Millennia ago, a battle raged in Earthrealm between Raiden, God of Thunder and Earthrealm's Protector, and Shinnok, a renegade Elder God who sought to konquer all of reality. Raiden was victorious, and he and Shinnok's fellow Elder Gods imprisoned him in the Netherrealm. Twenty-five years ago, Shinnok escaped his bonds and attacked an Earthrealm weakened from war with Outworld. Raiden and his fellow Earthrealm god Fujin were able to imprison Shinnok in his own Amulet. But there are other forces who seek to possess Shinnok's makeshift prison and use it as a source of power. Forces less than friendly to Earthrealm...
Earthrealm belonged to Shinnok. It became the staging area from which he would finish his war on the Elder Gods, which began eons ago.
The Elder Gods had lied to the denizens of the realms: They were not individual beings,
but merely parts of a greater collective known as the One Being.
Shinnok would merge the realms and awaken him.
Whole once more, the One Being devoured the Elder Gods. Shinnok watched with satisfaction.
This reality had finally come to an end.
