Sang Kendrica was not the only human city that was attacked. A total of 31 large cities with millions of people living in it were attacked by the beasts this time. Elena had actually sent her clones to all those cities in order to keep the death to a minimum degree for both sides. She also started to finalize her plans to reform this world.
Elena now needed a common enemy against whom both the human race and the beast race would be forced to team up. That was the only way how these two archenemies would co-operate with one another. Not only that but she needed to make their common enemy to be completely opposed to this world or one of the races might try to team up with them to eliminate the other party.
