Dardic languages
The origin of Piśāca is unknown, although it may be the personification of the will-o'-the-wisp. Pāṇini, in his Aṣṭādhyāyi, described the Piśāca as a "warrior clan". In the ancient literature, the Dardic people in the north of Kashmir were referred to as "Piśāca" and Dardic languages were called "Paiśāci". They are said to have been descendants of Prajāpati Kaśyapa.
