Return of the Goddess (Slow Update)

A young girl was chosen to become the priestess of Mother Nature. She is burdened with the responsibility to save the world from the war raging between the Gods and Goddesses. She grew up isolated from everyone else and from a young age she was not allowed to be herself.
After becoming powerful she successfully stopped the war but the peace was only for a small while. War broke out again and this time she could not stop it. In the end, she sacrificed her life to end the conflict and to restore life to the land.
She was born to be powerful. She was given the duty to save the world and the human race from the war between the supernatural beings. She died for others but she died in regret.
Never in her life had she lived for herself, to be herself. So when she was given the chance to live again in a new body, she decided that in this life she would live for herself. However, another war is coming and she can not escape from its clutches.
