Amara's niece.

Chuck's very first creation was his daughter Eden. She was considered a equal to himself and Amara... But Amara grew jealous of Chuck's love for Eden and sought to destroy her. So he created the archangels in order to protect her and he created a garden just for Eden on a place he called Earth. She loved the humans and all of Chuck's creations equally. Her life was perfect until the day it wasn't.
