The Dullahan // is a headless rider, usually on a black horse who carries his or her own head under one arm. Usually, the Dullahan is male, but there are some female versions. The mouth is usually in a hideous grin that touches both sides of the head. Its eyes are constantly moving about and can see across the countryside even during the darkest nights. The flesh of the head is said to have the color and consistency of moldy cheese. The Dullahan uses the spine of a human corpse for a whip, and its wagon is adorned with funeral objects (e.g., candles in skulls to light the way, the spokes of the wheels are made from thigh bones, the wagon's covering made from a worm-chewed pall or dried human skin). When the Dullahan stops riding, that is where a person is due to die. The Dullahan calls out the person's name, at which point the person immediately perishes.
There is no way to bar the road against a Dullahan—all locks and gates open to them when they approach. They do not appreciate being watched while on their errands, throwing a basin of blood on those who dare to do so (often a mark that they are among the next to die), or even lashing out the watchers' eyes with their whips. They are frightened of gold, and even a single gold pin can drive a Dullahan away.
