Naraka, also known as Narakasura, was a mythical asura king, the legendary progenitor of all three dynasties of Pragjyotisha-Kamarupa, and the founding ruler of the legendary Bhauma dynasty of Pragjyotisha. Though the myths about Naraka are first mentioned in the Mahabharata, later texts embellish them. According to later post-Vedic texts such as the Brahma Purana and Vishnu Purana, he was the son of Bhudevi, fathered either by the Varaha incarnation of Vishnu or Hiranyaksha. He is claimed as one who established Pragjyotisha. He was killed by Krishna and Satyabhama. His son Bhagadatta—of Mahabharata fame—succeeded him.

Varaha is an avatar of the Hindu god Vishnu, in the form of an Indian boar. Varaha is listed as third in the Dashavatara, the ten principal avatars of Vishnu.
