Despite the fact that Tumbbad portrays Hastar as a Hindu god, Hastar is not mentioned in Indian mythology. Because all mentions of Hastar were to be obliterated as part of the gods’ terms for sparing Hastar’s life, this information fits perfectly with the movie’s lore.
Even though the demon god was never to be worshipped, his memory was brought back to life by a family of Konkanastha Brahmins in the Maharashtra village of Tumbbad. Vinayak (Sohum Shah), the narrator of the Hastar legend and the film’s protagonist, claims that the family went against the gods’ wishes and began to idolize their fallen brother because his curse turned out to be a gift for them. Hastar wears a seemingly inexhaustible purse of gold coins later in the film, which members of the family try to dip their hands into… at the cost of their lives.
