The zheztyrnak, or coppernail, is a fiendish creature that troubles the people of the steppes. A demonic being who appears to be a beautiful young woman, she has long copper or brass talons, through which she drains the blood of her victims. The power of her voice is great: she can charm those she speaks to, sing them to sleeps, or even kill with it. As long as she only feeds on sleeping people, her claws do not wake them. She often joins a campfire in the wild at night, hiding her long claws in her sleeves and eating heartily of the traveler's rations before they go to sleep, either on their own or at her urging.

She is often richly dressed, with both gold and silver jewelry, that tinkles quietly as she moves...until she desires to move in silence.
