In a legend, Princess Thoibi of Ancient Moirang was once ordered by the King of Moirang to throw an egg. So, she and her slaves proceeded to a journey to carry on the task. The egg they brought fell on ground and got broken at the area of Goddess "Ichum Lairembi" in Khurkhul. From that time onwards, they started to live in the place and celebrate Lai Haraoba festival to please Goddess "Ichum Lairembi".
