The story conveys names and location of the Cheethu-Huluni or the twelve rivers that the Idu people came over in the region and settled around. The first accounts of the Idus or the Mishmis as the Ahoms called them are found in the narrations given by the neighbouring Ahoms. The Mishmis inhabited the deep jungles of what is now the Dibang valley.
