Spearfinger (Cherokee)
Spearfinger, or U'tlun'ta', is a monster and witch in Cherokee legend, said to live along the eastern side of Tennessee and western part of North Carolina. U'tlun'ta is Cherokee for "the one with the pointed spear”. Her right forefinger resembles a spear or obsidian knife, which she uses to cut her victims. Her mouth is stained with blood from the livers she has eaten.
Spearfinger, being made of stone, sounds like thunder when she walks, crushing rocks into the ground when she stepps on them. Her voice echoes down the mountains to the Cherokee villages and scares the birds of the forest away, which the people have traditionally seen as a warning sign.
