The story of this island began when a beautiful fairy princess – Mambang Sari and Mat Teja, a man who fell in love with the princess from the moment he saw her. Mat Teja met Mambang Sari at the lake and he was attracted by her beauty. Getting advices from a wise old man, Mat Teja finally managed to win the heart of Mambang Sari.

Living happily on earth, Mambang Sari bore Mat Teja a son. However, their happy moment did not last any longer as their baby died after a short while. Undergoing such a traumatic and tremendous pain, Mambang Sari decided to lay her child to rest in peace in the lake, Tasik Dayang Bunting (Dayang Bunting Lake). At the same time, she blessed all the childless and infertile women to be conceivable after bathing themselves in the lake.

Many have claimed to be successful.
