Brunei River

The river is also home to Jong Batu, a rock outcrop believed to be the remains of a ship belonging to Nakhoda Manis, a figure associated with the local legend of an unfilial son cursed into stone. Similar tales can also be found in the local legends of Indonesia and Malaysia.[14]

The inconspicuous tiny island of Lumut Lunting, which is described in Syair Awang Semaun as the site of a cockfight between the kings of Brunei and the Majapahit Empire, is one of several well-known local myths and tales that have been associated with the Brunei River.[15] At the mouth of the Brunei River, Lumut Lunting is positioned between Pulau Sibungur and Pulau Berambang, as opposed to Pulau Pilong-Pilongan, which is farther out at sea and closer to Muara. Both islands, Pulau Pilong-Pilongan and Lumut Lunting, have ties to a long-standing myth that dates back more than 500 years. According to legend, the incident occurred in the early years of Awang Alak Betatar's first sultanate, somewhere in the 14th century.[16]

At the time, a rooster owned by Awang Senuai, a relative of Awang Alak Betatar, was renowned for consistently triumphing in cockfights. In a cockfight, two carefully trained and conditioned roosters engage in combat as onlookers wager on the winner. The majority of conflicts result in the death of one or both roosters. Raden Angsuka Dewa, who also owned Asmara, a rooster reputed to be comparable to Mutiara, learned about this. Asmara was carefully cared for by his owner, who provided him with a unique coop and a golden plate that was hanging high. Asmara was rumored to be powerful, intelligent, and endowed with a unique ability. The native cocks were so horrified when he crooned upon entering Brunei that they did not crow for several days.[16]

The Majapahit King ordered that if he lost, he would hand over the 40 ships that were loaded with supplies to Brunei; but, if he won, he would receive more of the areas that Brunei currently holds and governs. Another version stated that Brunei would still be Majapahit's vassal state if it lost. For the cockfight in front of the Sultan's Palace, Asmara and Mutiara underwent thorough training. Many people came to see the battle the day it took place. The roosters started pounce, peck, attack, and kick each other as the enthusiastic onlookers cheered them on. Suddenly, Mutiara and Asmara both flew out of the ring. During the altercation, Asmara was stabbed and suffered critical injuries. Asmara disappeared from view, fell into the water unconscious from his wound, and transformed into a rock into an island (Pulau Pilong-Pilongan). When Mutiara attempted to follow, he fell into the river that the King of Majapahit had cursed. (Lumut Lunting), also changed into a rock and an island. Elder Kampong Ayer residents have a saying that Lumut Lunting will never be submerged, no of how high the water level rises. If it does, that portends a negative omen, such as the passing of a king or the happening of an unfortunate event.[16]
