Carrionite

The Carrionites were a witch-like species of humanoids, the only notable difference in appearance from near-Humans being wrinkled faces. They could also fly, dematerialise and rematerialise at will.

A group of three attempted to invade Earth in 1599. William Shakespeare had to give the performance of his life with the help of the Docotr and Martha Jones to save the world from the trio of flying witches, as the Earth would have been destroyed if he didn't.

The Carrionites were probably his inspiration for the Weird Sisters of his play, Macbeth. (DW: The Shakespeare Code)
