The twin Thunder Boys are the sons of Kanati and Selu. They live in the land of the west above the sky. When thunder sounds, the boys are playing ball. The lightning and the rainbow are their beautiful dress. The priests pray to the thunder and he visited the people to bring the rains and blessings from the South. It was believed that the thunder beings who lived close to the Earth's surface, in the cliffs and mountains, and under water falls could and did harm the people at times. These other thunders are always plotting mischief. The thunder beings were viewed as the most powerful of the servants of the Great Spirit. They were revered in the first dance of the Green Corn Ceremony held each year. They were believed to have brought the rains for a successful corn crop.
