The greatest of all spirits who lives in the sky. When he saw that his people were often hungry and sick, he sent his servant Kabonīyan to earth to teach them many things. It is believed that thunder is the dog Kīmat and that by the barking of this dog, the god makes known his desire. His direct messenger is the labeug, the omen bird. The chthonic goddess Agemem is his wife, and Adam and Baliyen are their sons.
Kadaklan also made the moon and the sun, which chase each other through the sky, and made the stars from stones. The god is invoked for rain, and is punitive if offenses are committed against customs.
