Orthena
From Tardis Wiki, the free Doctor Who reference
Orthena was a mother superior of the Sisterhood of Karn. She ordered Haspira to find the Eighth Doctor and Lucie Miller. She wanted to place them in a dispersal chamber. She told them about Cristophe Zarodnix and his Morbius fixation. (AUDIO: Sisters of the Flame, The Vengeance of Morbius)
