Yup’iks know them as Ircenrraat. Poncas refer to them as Gadázhe. Cherokees call them Yunwi Tsunsdi. In some cases, they are caretakers or protectors. Other times they are tricksters or menacing goblins. Most tribes have traditions that fit under the umbrella of "little people". They bear resemblance to fairies in other cultures. They are elusive supernatural beings that show up in stories or are invoked to explain good luck or misfortune.
