The Lotuko are an ethnic group from South Sudan.
The chief god of the Lotuko is called Ajok; he is generally seen as kind and benevolent, but can be angered. He once reportedly answered a woman's prayer for the resurrection of her son. Her husband, however, was angry and re-killed the child. According to the Lotuko religion, Ajok was annoyed by his actions and swore to never resurrect any Lotuko again, and in this manner, death was said to have become permanent.
