I was thinking, Luzon and the Tagalog Kingdom was occupied by the Bruneian Empire and the claimants outside of the banished Tondo/Tagalog Dynasty and the Bolkiah cadet are the Majapahit Dynasty...
I was thinking of a son of the last Majapahit Emperor, Girindrawardhana vanquishes the Bolkiahs out of Luzon and forms a new empire and a new identity and stops the Spanish from conquering Luzon or forms a Kingdom of Asturias like entity in North Luzon against the Bruneians and later the Spanish and reconquers the rest of Luzon in the age of exploration or second era of exploration, I am thinking of this as a scenario for a Comic book... any one interested..
