In Kisah Suang Jati, Lias' mother mentions the name Imbun when sharing the legend of Pulau Labi-Labi with her grandson, Malik.

Imbun is considered by many to be the founder of Tasek Merimbun, and the person whom the lake is named after. Legend has it that Imbun was hunting when he stumbled across a lake. He was so impressed by the lake's beauty, and by the bounty of food within the lake and nearby forests that he brought his family to reside there. As time passed, the area became more and more populated with Imbun's family and other villagers, and the lake also became known as Imbun's lake -- Tasek Merimbun.
