The top ten scariest monsters and demons from Celtic myth - PHOTOS

An artistic impression of a Dearg-due, an Irish name meaning “red blood sucker,” is a female demon that seduces men and then drains them of their blood.

The Questing Beast, known to be quick, was hunted down by many a knight, and in Celtic myth was chased by King Pellinore, an Arthurian character.

This beast appears not only in the legends of King Arhtur, but also in Edmund Spenser’s epic tale “The Faerie Queene,” which in part, tackles the troubled relationship between England and Ireland in the 16th century.

This is one scary creature you don’t have to worry about this Halloween – unless you dress up as a knight.
