Callie is the leader of the West Gate Wraiths
Callie has not revealed any of her life or death.
After the original leader of the West Gate Wraiths moved on, Callie was next in line for leadership and took over as head of the organization. She hates Vaughn Nottingham with a passion, seeing him as an usurper who leads a group not even connected to the original Eastern Ettins.
Hostilities have Escalated recently, erupting into a full-scale battle in the streets where Callie and Vaughn fought mano a mano in the Art District.
