Mab

Mab is a Faerie and the Winter Queen of the Winter Court; she is also called the Queen of Air and Darkness. She is the daughter of Mother Winter, and mother of Maeve, the Winter Lady.

Biography
Mab is easily among the most powerful beings in the dresdenverse. She has shown her power by performing great feats of magic with slight effort and has shown her intentions through her ways of punishing those who have betrayed or displeased her. First introduced in Summer Knight, she has purchased the use of Harry's services since his godmother the Leanansidhe sold the debts Harry owed her. When Leanansidhe came back to the Winter Court with a powerful athame, Mab forced her to sell Harry's debt to her to keep the balance in the court.

In Dead Beat Mab was shown to have the athame from Leanansidhe on her hip. She possessed it because she locked the Leanansidhe away for a time until she could be shown to have respect again to the queen.

"The gown was belted with a woven silver rope, and a slightly curved, single-edged knife of some dark, glassy material hung at an angle through it."

''“Because I do not tolerate challenges to my authority,” she said. One pale hand drifted to the hilt of the knife at her belt. “Certain events had convinced your godmother that she was no longer bound by my word and will. She is now learning otherwise.”''

As of Proven Guilty, both Lily and Maeve have expressed a concern that she is going insane. In Small Favor she does not speak for herself during most of the book but instead uses the Grimalkin as her "voice". When she does speak, it is described as razor sharp and shakes the area where Harry is, making his nose and ears bleed. Harry's reasons that the cause of this condition is because of her fury over the attack on Arctis Tor in Proven Guilty.

Appearance
Mab's appearance fits her title. She has pale skin and white hair. Her eyes are green. When appearing among mortals she tends to dress in contemporary clothing; her chosen colors are mostly blues and dark colors. Some times she uses Grimalkin to speak for her, while she herself remains silent.
