Charlotte was initially a headhunter. She was sent out to kill Eilise as she was considered "easy pickings". Eilise's territory was to be claimed, but Charlotte did not like the idea of assassinating someone so young who clearly had no idea what was happening. Charlotte instead challenged Eilise to a fair one-on-one. To her surprise Eilise packed more of a punch than she thought and lost the fight. Charlotte was so impressed that she wanted to join Eilise's pack and protect the woman from the threats around her. They became fast friends and Charlotte regards Eilise as a sister and would do anything to keep her safe.
