Benandanti

"Some older Hand mebers speak of mortals known as the Benandanti. They are humans capable of leavinf their bodies and taveling into the Underworld. It is said that once, long ago, som of them walked the streets of Enoch in disguise and secretly studied in the libraries of the Tal'mahe'Ra. Most Kindred gave never heard of them, and most of those who have do not believe in their existence. They claim no living soul can enter the Underworld. Still, some fear valuable secrets were stolen by the Benandanti, which might be traded to others in the Underworld, leading to an attack on Enoch, or at least ending its peace."
