Bakunawa rose from the sea, her scaled and slick and massive form rising up over cities and mountains, her teeth glistening and her eyes filled with desire, and she opened her mouth wide. The moon, Mayari, looked on as the Celestial Eater grew closer and closer, stopped only when Haliya arrived and struck the great serpent with her sword. Haliya's mask reflected the warrior goddess' rage as she fought the serpent back into the sea, forcing it to retreat. It would only be a matter of time before an attempt on the moon's life would be made again, be it Bakunawa or one of the other Celestial Eaters. And as she laid to rest, she knew both herself and the mortal races would need to be ready. The Islands of Sina Una is a new Campaign Setting for 5th Edition that pulls from precolonial mythology and culture of the Philippines. In the time since Bakunawa's last attack the mortal races that inhabit the island recover slowly as life goes on. While some do battle with the monsters that roam these lands, others work as intermediaries, communicating between spirits and deities to help protect and guide their people. And yet, there are still others who choose to align with the terrible Celestial Eaters, to destroy the moon and bring about the end of all things.

A venom maw hydra lair suitable for four or five 10th-level characters. The Red Craw Marsh, so called because of the delicious and plentiful red crayfish that live in the area, is a boon to the nearby village. More than a few intrepid souls brave the swamp each season to collect the crayfish. They either sell the crayfish to local establishments or ship them to nearby cities, where they earn a good price as the crayfish is a delicacy among the wealthy. The villagers have established a tentative peace with a clan of trollkin that inhabit the swamp. The crayfish collectors pay a small fee to the trollkin, who allow them to ply their trade in the marsh without (much) interference. It is a tense but profitable relationship for all involved. A powerful creature has moved into the marsh, however, threatening the delicate balance. When a venom maw hydra decided to move to the area of the marsh between the human and trollkin villages, it brought along a number of creatures that worship and serve it. This hydra and its allies have killed some of the crayfish hunters and some of the trollkin. Each side, unfortunately, believes that the other has broken the truce, thus stirring up animosity and putting both groups on the verge of war.
