Bulan

Bulan is the primordial god of the moon in pre-Hispanic Bicolano mythology.
He lives in "Kamurayan(heavens) and is depicted as an adolescent boy with extremely fair skin, with eyes and hair darker than midnight,  lithe body and comely features. He was worshiped alongside Asuang by the baylan (priest and shamans in pre-Hispanic Bicol who dressed and acted as female). Also, some believe that the First class municipality in the south of Luzon island, Sorsogon Province was named after him.

He had a younger sister who literally came from his body named Haliya. In the stories, Haliya was Bulan's daughter and defender (the gods could not age Bulan forever remained pubescent) enticed by the wind people or taong lipod to descend into the earth to bathe in its waters, she, in turn, convinced her brother Bulan do go down with her. Bulan and Haliya descended and all creatures were at awe with their luminous and white beauty.
It is said that Bulan and Haliya they were so beautiful that the vicious Magindara became docile. Their beauty also reached the underworld which was the domain of the Bakunawa.
The moon was so focused on playing with the mermaids that they did not notice the god Bakunawa, offended he wanted revenge. (very similar to the Visayan version of the story)
The next night Bakunawa, a huge fish-like-dragon leap to the sky to consume the moon. Haliya became the arch-enemy of Bakunawa ever since

Bulan and the vicious mermaids and the flying sharks

Long ago the inhabitants of Bicol believed in the existence of vicious man-eating mermaids called Magindara. The magindara were lovely half women half fish that would lure men to the sea and drown them. The Bicolano's also believed in winged sharks called Pating na Pakpakan that could fly and devour men. The waters of Bicol were feared because it was monster-infested. One night the villagers heard beautiful voices coming from the sea, they did not dare go see, but when they looked up a celestial divinity was descending. It was Bulan, the god of the moon. He was said to be so fair and luminous that the vicious mermaids became tame, and that the flying sharks dropped from the sky and almost sank into the water forgetting how to swim and fly in the presence of the moon god.
