The Chronicler of Ages

As time passes, Aylia lasts through the ages with her consciousness transferring from one body to another, but while others forget what it means to be human, Aylia remembers. Due to her hyperthymesia, she hasn't forgot anything since the day she was born. She remembers every day, from when people lived normally to the day the dominus began forcing their totalitarian regime on to the imus, or the lesser people of the world. Each person who lives in their world has been selectively cloned through the years and they have all been kept in check by the threat of losing their immortal life if they step out of line. But when the dominus begin changing each person's memories during their rebirths, she knows she has to stop them, but how do you stop someone who controls everything and everyone?
