Your mother is a goddess named Hecate. Hecate is the Titan Goddess of witchcraft, necromancy, ghosts, crossroads (choices), magic and the Moon in Greek Mythology. She is a Chthonic deity and one of the Titans who allied with the Olympian Gods in the Titanomachy (Titan Wars), and remains a loyal ally to them ever since. Your mom left you to live on earth, but she's watching you all the time. And if she is on earth, she will be very big, she can control her growth in any way
