Xavion and Sareyus

During the Earth's third incarnation, eight of the nine gods craft a warrior. He is Xavion, and at thirty years old, he is in the midst of warring empires in the continent of Nodin. Being mixed of all human ethnicities, Xavion is often discriminated against. As a champion representing five rival minorities, Xavion is hell-bent to purge imperialism from the north.
Sareyus, the goddess of fire, protests Xavion's creation. Her anger of the pantheon's ignorance forces her to take action. While in the guise of a human, she is thrust into the political instability. Upon meeting, they are smitten. Together, they uncover conspiracies that could destabilize Heaven and Earth.
