In the creation myth, God Khamlangba was grown out of Atiya Sidaba. He was a great hunter, warrior and miner. He lived with Goddess Huimu Leima and a son named Amudon was born to them. After this, Khamlangba left Ancient Kangleipak (Antique Manipur) for Tripura () in search of iron ores. When he returned to Ancient Kangleipak (Antique Manipur), he settled in Kakching. The people of Kakching worshipped Him. Later, "Kakching Haraoba", a new form of Lai Haraoba was developed. This account is evident in the "Khamlangba Khunggumlon" text.
