Tablibik

 was an inhabitant of Sair, a village whose inhabitants had the ability to conjure demons. Peri found him very attractive, but after talking with him for an hour, decided he was vain, arrogant, and a creep. When she walked away, he cast a spell on her, causing her to be fascinated with him. He controlled her, convincing her to stay in the village when the Fifth Doctor left. The Doctor, with the help of Papus and Rasphuia, released Peri from his control and he was punished. (PROSE: Fascination)
