When MK11 ended, Liu Kang and Raiden were on the dawn of time and has to reset history. Anyone notice that in both endings, neither Liu Kang or Shang Tsung are at the dawn of time because Kronika never got the crown to set history back that far. In liu Kang's ending, he journeys to the past to prepare The Great Kung Lao for Mortal Kombat. In Shang Tsung's ending, he hasn't done anything to time. All he did was take a seat as an elder god with Fujin and Raiden at his service. All of the other elders were wiped out by Cetrion and of course she sacrificed herself to Kronika. Shang is now conquering realms instead of warping or manipulating time. In Liu Kang's ending, all of his friends are dead. In Shang Tsung's ending, we could conclude that all of Liu Kang's friends survived as we saw Johnny and Cassie taken prisoner. As stated above, the revenants not disappearing means Kitana, Jade, and Kung Lao could be alive
