From what I had read the Majapahit empire was formed due to the alliance of Raden Wijaya and the Mongols of Yuan and aside from that he had an unacknowledged wife from the Northern Part of the Philippines - which is stated in local epics in the northern part of the philippines.
The wife was the first wife of Raden Wijaya, which was the reason why the Northern part of the Philippines fell to Majapahit influence, without the Majapahit influence the North of the Philippines would remain under Pasai and later Aceh influence causing it to be muslim in the same time as Sulu, the same would happen to Java I think..there would be less survival of the Hindus and Pagans in the East Indies
