Coralie is a very quiet, reserved, and mostly non-confrontational 13 year old girl. 

Her father was part of a cult, but her mother still loved him dearly. At a young age, she helped lure and kidnap children for her cult to use as sacrifices. 

When Coralie was around seven years old, she witnessed an 'incident,' where her father was holding a heart in the jar and referring to it as her mother. He was apologizing for what he did. When Coralie witnessed this, she ran away.
