As to the northeastern people, they have a unique festival called ngan bun bangfai or the Rocket Festival. It is held at the beginning of the rainy season as an annual plea to god for plenty of rainfall. A legend has it that once a god called Phaya Thaen, who was the most powerful in heaven, and was in charge of the regulation of rainfall in the world, was angry with the animals on earth. To retaliate, he stopped the rain completely, causing distress to all creatures. Greatly troubled, the animals made war with Phaya Thaen twice, but were defeated on both occasions.
