Mertil
From Tardis Wiki, the free Doctor Who reference
Mertil was Anulf's second wife and stepmother of Seksa.
She didn't agree that Seksa was to become leader instead of herself.
She mistook Turlough for a Taker, because of his red hair.
She killed Seksa's mother in order to take control and shot Seksa after revealing this to her. (AUDIO: The Whispering Forest)
