Based on the Legend of a Filipino Warrior Princess, Urduja.
The story of Princess Urguja is a Philippine folk heroine in the region of Pangasinan.
Urduja (ca. 1350 C.E - 1400 C.E.), is a legendary warrior-princess who is recognized as a heroine in Pangasinan. A historical reference to Urduja can be found in the travel account of Ibn Battuta (1304 - possibly 1368 or 1377 C.E.), a Muslim traveler from Morocco. Ibn Battuta described Urduja as the ruler of Kaylukari in the land of Tawalisi. Ibn Battuta stopped by Tawalisi, which is believed to be around the Pangasinan coastal town of Sual, on his way to China. Princess Urduja was described as a daughter of a king named Tawalisi of a land that was also called Tawalisi. The ruler of Tawalisi, according to Ibn Battuta, possessed many ships and was a rival of China, which was then ruled by a Mongol dynasty. Ibn Battuta sailed for 17 days to reach China from the land of Tawalisi.
Ibn Battuta made a pilgrimage to Mecca and he traveled to many other parts of the Islamic world. From India and Sumatra, Ibn Battuta reached the land of Tawalisi. Ibn Battuta described Princess Urduja as a warrior princess whose army was composed of men and women. Princess Urduja was a woman warrior who personally took part in the fighting and engaged in duels with other warriors. She was quoted as saying that she will marry no one but him who fights and defeats her in a duel. Other warriors avoided fighting with her for fear of being disgraced.
Those that do, fought her in the shadows not to own her as their wife, but to destroy her once and for all.
