High Quality Content by WIKIPEDIA articles! The Nac Mac Feegle (also known as Pictsies, the Wee Free Men, the Little Men, `Person or Persons Unknown, Believed to be Armed`, `That`s him, the third one from the left!", and occasionally `The Defendants`) are a type of fairy folk appearing in Terry Pratchett`s Discworld novels Carpe Jugulum, The Wee Free Men, A Hat Full of Sky, Wintersmith and I Shall Wear Midnight. Aside from being six inches tall, they just about invert the Victorian concept of mystical and refined fairies, and hark back to the fairies of folklore, who were generally seen as occasionally helpful thieves and pests.
