Ever wonder what those magic circles of stones in the English countryside are for? They're to keep the elves out.--This text refers to the Mass Market Paperback edition.
Elves are nasty (besides being brutish and short). They're
vicious. They love cruelty. Plus, to make things worse, elves have got It. Glamour. Style. Humans find elves absolutely irresistible. They actually think elves are cute!
So when an infestation of Faerie Trash invades the Kingdom of Lancre, upsetting the Royal Wedding Plans
(Not to mention the Annual Morris Dance), the ordinarypeople of Lancre are helpless. It's up to the witches, ledbyGranny Weatherwax, to deal with the viciouslittle bastards.
Which is alI right with Granny. She thinks elves are cute too. And that makes them even more fun to kill.
