Carmilla's Allure is likely inspired by "Carmilla," a Gothic novella by Joseph Sheridan Le Fanu. First published in 1872, it tells the story of a young woman named Laura and her susceptibility to the attentions of a female vampire named Carmilla. "Carmilla" predates Bram Stoker's Dracula by 25 years.
