Maliketh Baal, the current Demon Emperor, declared the horns of war on the world as the long-awaited Great War was finally happening in the new timeline.
Compared to the original, this phenomenon took place way earlier than it was supposed to, but at the moment, nothing really stayed true to the original path.
Kahn met Argos and Morpheus way earlier, but in a different order, while the veiled existence of the Demon God itself resurrected itself 70 years earlier than the original timeline.
And the Demon God was seemingly aware of most of the changes brought by original Kahn, aka the Martial Emperor. On top of it, he was also aware of Kassandra's existence and had been monitoring her for years before anybody even knew.
The Demon Emperor basically indicated that the Demon God had ways to see the changes in the timeline and even shift his own past as if he had a method or a power to inform his original self that lived in the past.
