"Lemora: A Child's Tale of the Supernatural" (1973) starring Lesley Gilb Taplin, Cheryl Smith, William Whitton is a very bizarre vampire movie.
She eventually gets a bus driver to driver her to the backwoods town of Asteroth. She discovers from the driver that he doesn't like to go to this town because there is some sort of disease there. On the way, the bus is attacked by a hoard of mutant like creatures that come out of the woods. Lila gets away but only to be captured by people working for Lemora.
Lemora lives in a large Victorian house and has a witch like housekeeper and several creepy little children. She is also the queen of the vampires and we find out that the disease is turning some of the vampires into those nasty mutant creatures who have been rampaging through the area.
Lemora, is quite the figure. She is tall and severe looking in her Victorian attire. She is very pale with red cheeks. She tries to win over Lila but is having a hard time convincing her that she has her best interest at heart. It also turns out her father has turned into one of the mutants.
