Maharani Ajabde Punwar died of cancer, right after giving birth to Pratap's successor. No, Rani Bhatiyani did not kill her. She was too scared. She had a dream in which she saw that Phool saw her trying to kill her and ordered a death punishment. And Ajabde died before the marriage of Phoolkunwar and Pratap. Her death wish was to see them taking the saat phere. But unfortunately, she died before that could happen.
