Matron

The Matron of the Vale Coven is a woman with silver-white hair who appears both young and old. She is distrustful of NIMA.

Night Air Syndrome
The Matron was approached by a mysterious woman and agreed to some sort of deal with her in exchange for rare and valuable ingredients. As a result of this transaction, she was asked to help capture a vampire - Angel - who had escaped the control of the mysterious woman and her associates. The Matron had her coven track down and capture Angel, who was kept under a strict lock-and-key until a slip-up and he managed to escape.

When asked by Seb if she knew anything of the vampire's whereabouts, she lied and said that she did not. She refused to consent to further questioning.
