Marvi was a beautiful lady of Malir, a village in Tharparkar desert of Sindh. One day, she was filling water in her pots from this well (which is now named as Marvi well - ماروي جو کوھ) , the king Umar caught sight of her. He was captivated and enamoured by her dazzling charms and winsome personality. Umar proposes her to marry and tries to attract and win her with jewels and his great riches. But Marvi was unimpressed and refused his proposal, as she was in love with her cousin (Khet) and deeply devoted to him. Infuriated by her refusal, Umar felt humialiated and decided to teach her a lesson. He abducted her and imprisoned her in his magnificent palace. He tried his utmost to convince Marvi to marry him. He wanted her to forget her people and start living luxurious life with him in his palace. But, out of her love for her people, old huts, her village, she remained unmoved and indifferent to all his demands and temptations. She refused to even eat, getting weaker and weaker as the days went by. She kept requesting him to set her free and allow her to meet her own beloved Marus (people).
When all her beseeching failed to move Umar to set her free.
