The scenes of the Big Choas were awfull, she was just in time to come between the two sides and she urged for negotiation quite loudly. The two armies that would otherwise slaugthered each other agreed on terms of peace.
Athena helped to rebuild up the war-torn cities into vast cities. These cities transformed from being almost wiped out to being places of where people of with different backgrounds come to together and collaborate in different tasks to improve humanity.
To prevent futher unrest she vanished the memories of the masses, who were involved in the Big Choas and the appearance of her. She decided to move back in time to her own city. Athena prevented the downfall of the human race without no living and dead soul have any knowledge about it.
When she returned back to ancient Athens, nobody noticed that she just saved the future of civilization. She ruled for many years over the city of Athens, until people forgot what she did and she vanished into the history books.
