One day Singhia saw the princess' maid in the market. Local fables say, he used his black magic on the oil she was purchasing so that upon touching it the princess would surrender herself to him.
The princess, however, seeing the tantric enchanting the oil, foiled his plan by spilling the entire magic oil on the ground.
As the oil struck the ground it turned into a boulder, which crushed Singhia, says the fable. Dying, the magician cursed the palace with the death of all who dwelt in it.
