Mother Blackbeak is the High Witch of the Blackbeak Witch Clan and Manon's grandmother.
Even after beginning to age, Mother Blackbeak is distinctively beautiful with long, ebony hair sprinkled with silver and eyes flecked with gold.
Mother Blackbeak is cold, calculating, and ambitious. She is violent and brutal, and she cares little about the casualties in her schemes, to the point that her behavior tends to border on sociopathic. She is willing to turn on her own kin should they disappoint or defy her: She killed her own daughter, Lothian, for her romantic involvement with a Crochan Prince, and showed no reservation about viciously injuring her granddaughter, Manon, when the latter attacked her to avoid executing Asterin Blackbeak, who is Manon's second in command.
