Going back to the 20th century to correct history is difficult and risks falling into historical nihilism. Making everyone happy isn't something that can happen overnight.
When Aurora opens her eyes again, 200 years have passed since her death in her previous life. The Grego calendar is no longer in use. It is now called the Gospel Era, in remembrance of the "Gospel" that arrived at the start of the new century, 100 years ago, spread by a super-civilization from beyond the Milky Way, and radically transformed human biology.
Sadly, the descendants have proved unworthy. Even though the "Gospel" has enhanced human intelligence and physical strength, and technology has advanced by leaps and bounds, humanity is still struggling on Earth. We have not only failed to leave the Milky Way or the Solar System, but hundreds of millions of people still cannot escape poverty, toil, cold, hunger, disease, violence, enslavement, and inequality...
Your name is Aurora, and the meaning of your life is inherited from Avrora. The mission of the October Revolution is not yet complete. You cannot sleep yet. The last reactionary bastion of the old society is the fruit borne by the seeds you scattered. It is your duty to put an end to them with your own hands.
