The "Spiral Coterie"

Described by Madeline before her death, this small group appears to be made up of Jax, a Caucasian with a snake tattoo on his forearm, Rosie, a Nosferatu, and an unknown woman in a pantsuit. They educated Madeline about resopnances and dyscrasias (but not the Masquerade) and are suspected to have some involvement in Ingrid Voldaren's disappearance.
