Kayra

Kayra, ‘the merciful king’, is described as both father and mother and lives in the seventeenth layer of heaven. He planted the tree of life, Ulukayın.

Some tellings call him the child of Tengri and the supreme god of the pantheon. In Altai tradition the brothers Ülgen and Erlik were created from him, and in a legend recorded by Radlov he cast the first human from heaven, naming him Erlik.
