Secondary character in my story.

Petra, who's a goddess of war and peace (each god in my AU is a god of two opposite things, ex. creativity and commonness, creation and destruction, righteousness and fraud, love and hatred etc). One of the side characters in my story. Stoic and calculating (and secretly a little soft-hearted), Petra is that person, who's both a good ally and a friend. Holding high recognition among other gods for having a strong feelings of justice and duty, she's often tasked in bringing order by making peace among one group of gods, and bringing war on others, who break the rules. She firmly stands on her principles of what is "right" and will hardly change her opinions... Unless..?
