Jogah are small spirit-folk (similar to faeries) in Iroquois mythology. They represent aspects of nature, and are split into various groups based on their relation to the world: the Gahonga are the jogah of rocks and rivers, the Gandayah make the Earth fertile and the Odhows control the spirits of the underworld, preventing them from rising to the surface of the Earth.
