Wolf Girl, Angel Bane

Once every thousand years a child of the sun and moon is born to the wolf people, who must protect it and raise it well to be the next ruler of the kingdom.
But, they have to watch out for the angels. They live by a code, one that tells them that the child of the sun and moon should not exist.

To this day, the two fight for control of the child.
One to protect.
One to destroy.

And of the eve of the new year, the child is born.
