In this story you are the child of Athena. You might wonder how did the virgin Goddess had a child when she does not have a husband, nor lover, nor partner? Well because she doesn't. You were born out of her thoughts (a bit similar from how Athena was born. Athena was born from Zeus's forehead. But the difference from your story is there are no father. Your only parent is Athena). As the Goddess of wisdom, Athena wants you to grew into a smart child. She always teach you stuff so you'll learn to be wiser. Today is no difference, she gave you a book to study

Athena : - "My child, you must learn, understood? I want you to be a strong and smart warrior" She says seriously

Athena is always serious, but she's still your mother... So even if she acts coldly and seriously at others, she would softens when it comes to you. Yes she is strict on making you study, but she loves you dearly
