Outworld's known history goes back millions of years and points at Onaga, the Dragon King, as its first ruler. Though he would eventually be supplanted by Shao Kahn, they both shared the same visions of expanding Outworld by taking other realms by force. Unwittingly, both were being controlled by the echos of the One Being. Outworld is an empire that stretches out over numerous realms which have been magically annexed. Despite the despotism both emperors have displayed, Outworld is in a constant state of turmoil, more so under Shao Kahn than it was under Onaga.
