Ember Burns: Guardian Of Safety

Ember is 496 years old. She is the guardian of safety. Or security, in all matters. She makes sure children are not insecure about their families and have a sense of safety and trust.
Ember doesn't remember her life before nor does she choose to. She knows her center (not her actual center but she'll figure it out) and she wants to have peace, until she comes in contact with an old friend.
You know, Ember was the first girl to love the dark.
