Ancient Mai

Ancient Mai is a witch and a member of the Senior Council. She first appears in Summer Knight.

Description
She is over 400 years old, with granite colored hair, "rheumy" eyes and is said to be very creepy and scary.

She has "precious little gift when it comes to actual combat magic".

Ancient Mai is Chinese and, as Harry Dresden describes her, she looks a delicate and frail as an eggshell teacup. She has long white hair with jade combs holding it up. She still has a haunting, ethereal beauty, though old even by Council norms. Her eyes are dark, peircing and merciless.

Dresden finds her a very scary person.

Biography
She appears to handle contact with other supernatural powers for the Council, having sent emissaries to both Faerie Courts at the start of Summer Knight.

Summer Knight
In Summer Knight, she does not trust Harry Dresden, citing his dangerous attitude, and she voted against him when the Council deliberated on whether to give him to the Red Court.

Along with the Merlin, Arthur Langtry, she is suspected of being the traitor among the Council, as her whereabouts during many of the attacks are unaccounted for.

Turn Coat
In Turn Coat, she repeatedly tries to have Dresden arrested for harboring a wanted fugitive, and is angered when Ebenezar McCoy and Joseph Listens-to-Wind refuse.
