Returning to the present, Tatsu was horrified to see that not only do the Allies and Soviets still exist, but in an ironic repeat with what happened with Cherdenko, a new fourth world power called the Celestial Empire now rules over Japan. Having outlived his usefulness, Tatsu erased Möngke Khan from the timeline and destroyed their technology, leaving the now leaderless and overextended Mongol Empire to tear itself apart.

Under Tatsu's orders, the Mongols went on a rampage across the entirety of Medieval Europe, leaving a path of destruction that Tatsu hoped would prevent the rise of the Allies and the Soviet Union in the future.

The Imperials went back in time to the middle ages and saved Möngke Khan from a fatal cannonball that would have killed him.
