Yin and Yang

A long time ago, way back when gods still descend in the land and join humans, there lived a child who was born from the woe of the world. She had carried the underlying sad and dark side of the world. And yet, she was kind, unsuspecting, and innocent. 

The goddess who watched over this child looked at her in pity, witnessing the miserable life she led, was leading, and would lead. Shunned by everyone, the lonely child looked up and prayed to her, asking for a friend. So the goddess who pitied this innocent soul gave her wisdom.

But the wisdom that was supposed to tell the child that the goddess would always be with her was perceived as something else. Instead, the child took a weapon and split herself in half so she would always have a friend. Disheartened by the death of the young child, the goddess descended to cradle her.
