Punnu
Mir Punnhun Khan (Mir Dostein) was the son of Mir Aalii or Ari, a Baloch king of Kech, Balochistan.
Sassi
Sassi was the daughter of the Raja of Bhambore in Sindh (now in Pakistan). Upon Sassi's birth, astrologers predicted that she was a bane of the royal family's honor. The Raja ordered that the child be put in a wooden box and thrown in the Sindhu. A washerman of the Bhambore Village found the wooden box and the child inside. The washerman believed the child was a blessing from God and took her home. As he had no children of his own, he decided to adopt her.
Sassi
Sassi grew up to be as beautiful as the fairies of heaven. Stories of her beauty reached Punnu and he became desperate to meet Sassi. The handsome young Prince, therefore, traveled to Bhambore. He sent his clothes to Sassi's father (a washerman) so that he could catch a glimpse of Sassi. When he visited the washerman's house, they fell in love at first sight. Sassi's father was dispirited, hoping that Sassi would marry a washerman and no one else. He asked Punnu to prove that he was worthy of Sassi by passing the test as a washerman. Punnu agreed to establish his love. While washing, he tore all the clothes as, being a prince, he had never washed any clothes; he thus failed the agreement. But before he returned those clothes, he hid gold coins in the pockets of all the clothes, hoping this would keep the villagers quiet. The trick worked, and Sassi's father agreed to the marriage.
Punnu's brothers
Punnu's father and brothers were against his marriage to Sassi (Punnu being a prince and she being a washerman's daughter) and so, for their father's sake, Punnu's brothers traveled to Bhambore. First, they threatened Punnu but when he didn't relent, they tried more devious methods. Punnu was surprised to see his brothers supporting his marriage and on the first night, they pretended to enjoy and participate in the marriage celebrations and forced Punnu to drink different types of wines. When he was intoxicated they carried him on a camel's back and returned to their hometown of Kech.
The lovers meet their end
When Sassi woke up the following morning, she realized that her brother-in-law had cheated on her. She became mad with the grief of separation from her beloved and ran barefoot towards the town of Kech Makran. To reach it, she had to cross miles of desert. Alone, she continued her journey until her feet were blistered and her lips were parched from crying "Punnhun, Punnhun!". The journey was full of dangerous hazards. She was thirsty when she saw a shepherd coming out of a hut. He gave her some water to drink. Seeing her incredible beauty, he tried to force himself on Sassi. Sassi escaped and prayed to God to hide her. God listened to her prayers, the land shook and split and Sassi found herself buried in the valley of mountains. When Punhun woke in Makran he could not stop himself from running back to Bhambore. On the way, he called out "Sassi, Sassi!" to which the shepherd told Punnhun the whole story. Punnhun also lamented the same prayer, the land shook and split again and he was also buried in the same mountain valley as Sassi. The legendary grave still exists in this valley. Shah Abdul Latif Bhittai sings this historic tale in his Sufi poetry as an example of eternal love and union with the divine. But according to the famous tale by Hashim (poet) (Hashim Shah) Sassi dies while crossing the desert.
