Avíreri, also called Nabiréri, is the great transformer of the mythic age. By his power he turned the first beings into the animals, plants, hills, and watercourses of the world, and he is credited with instituting the dry and rainy seasons and the succession of day and night; many named features of the landscape are said once to have been people whom he transformed. In the central narrative he wreaks havoc, changing his own young kinsmen into rocks, monkeys, and insects, until he is tricked into falling into a hole and carried off to the place called the river's end, where a strangler vine wraps him fast; there, immobilized, he is said to remain. Sources differ on whether Avíreri is to be identified with the moon: his role as a lunar transformer is widely noted, but Weiss treats him as a figure distinct from Kashiri.
