The Gandayak (also called Jogah) are little people from the Haudenosaunee tradition—commonly known as Iroquois mythology—a confederation of closely related tribes located in the northeastern United States and adjacent districts in Canada.
Gandayak are similar to fairies but with some of the characteristics of an elemental. Traditionally described as spirits in dwarven form, they have power over living plants of all sorts, and control their growth and health. They have some power over fish as well. As most elementals, they care for their surroundings, helping living beings and punishing those who are disrespectful to the natural world.
They may play tricks, and might even be dangerous to people who disrespect them or their natural home, but they are generally friendly towards the Iroquois, and will sometimes do favors for people who leave tobacco or other offerings for them. They are usually invisible but sometimes reveal themselves to humans, particularly to children, elders, and medicine people.
There are several different types of Gandayak. For instance, the Gahongas (Stone Throwers or Stone Rollers) are earth spirits who live on rocky riverbanks and caves. They are enormously strong and are responsible for moving rocks around the countryside. Gandayah (Drum Dancers) are nature spirits, who often help respectful Iroquois farmers with their crops. They got the name "Drum Dancers" because they are always invisible, so only the sound of their drums signaled their presence to the Iroquois.
