Devendra P. Varma, the author of The Vampire in Legend, Lore, and Literature, noted a story about a vampire in Sikkim, a neighbor of Tibet.
In the early eighteenth century, Princess Pedi Wangmo plotted to kill her half-brother. With the assistance of a Tibetan doctor, she bled Chador Namgyal to death and drank his blood. The princess was able to escape the palace, but she was caught soon after.
The Princess and the doctor were killed.
Some believed that after her death, the Princess became a vampire. The story was recounted in a fresco in a monastery in Sinon, near Mt. Kanchenjunga.
