The unknown titaness

The prophecy

So I'm going to start from the beginning. My name is Maria Diaz Hernadez. I am Athena's unknown twin. You see Gaia, the evil earth being, my great-grandmother, was mad that the olympians beat her children, the titans. She wanted revenge on her grandchildren but she bid her time. A couple of centuries after the titans great defeat, Zeus, king of the gods met a titaness(my mother) Metis. She was his one love. He made her queen of olympus and openly declared his love for her. Gaia who was in a deep slumber after her childrens great defeat saw this as her perfect time for revenge. So she appeared in a dream to Zeus and told him that Metis and his child would overthrow him. Zeus is a power hungry king. He turned Metis into a fly and swallowed her. Little did he know she was pregnant. With twins.
